Goodbye, Francisca

Francisca Adeus Dead Died Franciscana Dolphin Dolphins Toninha Toninhas

It is with great sadness that we must announce that Francisca, the Franciscana dolphin calf that we were able to accompany for more than a year in the care of our partner R3 in Brazil, has passed away.
After her rescue on January 3, 2025, on a beach, Francisca initially developed very well and enjoyed excellent health for many months. During this time, she gave us valuable insights into the biology, needs, and vulnerability of her species.

With her strength, her will to live, and her zest for life, Francisca became an important ambassador for the critically endangered Franciscana dolphins. She touched people around the world and made it clear that this species of dolphin exists and how urgent it is to protect it.

However, on January 5, 2026, her health suddenly and dramatically deteriorated. Despite all efforts and intensive attempts to save her, her life could not be saved.

We would like to express our special thanks to the dedicated team at R3, who cared for Francisca around the clock for over a year with great expertise, dedication, and love.

Merry Christmas and a Happy New Year!

Milestone for the protection of the Lahille dolphin (Tursiops gephyreus) in Argentina

workshop tursiops gephyreus argentina workshop lahille dolphin dolphin argentina

Argentina hosted its first national workshop on the protection of the critically endangered Lahille's dolphin, one of the world's most endangered dolphin species. This meeting represents a historic step forward for marine mammal conservation in the country and strengthens the joint strategy for the conservation of Tursiops gephyreus.

The two-day workshop brought together numerous experts from academia, government institutions, ministries, NGOs, the fisheries sector, and international partners. Intensive specialist presentations, productive discussions, and an exceptionally cooperative working environment highlighted the extent of the shared commitment to protecting this endangered dolphin species.

The collective motivation and constructive atmosphere clearly demonstrated that concrete and effective steps are being taken to stabilize and promote the Lahille dolphin population in the long term.

Special thanks go to Fundación Azara, which organized the workshop in Buenos Aires and is working hard to promote key conservation measures for this species.

We would also like to thank all the experts from academia, institutions, and government agencies involved for their expertise, passion, and forward-looking vision.

This workshop laid a crucial foundation: the development of a coordinated and scientifically sound roadmap for the coming years, based on international cooperation, solid research, and joint conservation strategies. This is a significant step for the future of Tursiops gephyreus and the protection of marine biodiversity in Argentina.

Vaquita – good news from the Upper Gulf of California!

vaquita excursion 2025 frida vaquita marina gulf of california

The 2025 research campaign confirms that the vaquita —the world's most endangered marine mammal—continues to live, thrive, and reproduce in the Upper Gulf of California.

Researchers estimate that between 7 and 10 different individuals have been sighted within the protected area, including newborns and young animals—clear evidence of ongoing reproduction and survival.

Acoustic and visual data show that most vaquitas remain within the Zero Tolerance Area and its extension zone, although some have also been recorded in the northwestern part of the protected area—an area that currently does not offer sufficient protection.

The complete abolition of fixed nets remains the most important measure for the recovery of the species.

The research campaign also included the participation of young people from San Felipe, who are continuing their training as local observers of the vaquita and the marine ecosystem. This ensures that conservation efforts are based on community involvement and local responsibility.

YAQU PACHA supports the protection of the vaquita in collaboration with PESCA ABC and promotes alternative fishing methods using handlines, as well as projects to improve and establish sustainable fishing practices. These measures enable sustainable sources of income that do not endanger the vaquita.

Registration form (online participation also possible)


The Lahille dolphin (Tursiops gephyreus) – one of the most endangered dolphin species in the world – is at a critical juncture. With fewer than 500 individuals remaining and only about 150 animals in Argentina, coordinated action is urgently needed to prevent its extinction.

In response to this crisis, Fundación Azara, Nuremberg Zoo, YAQU PACHA, and Fundación Mundo Marino are joining forces for a two-day workshop to:

• Review the Conservation Management Plan (CMP) of the International Whaling Commission (IWC),
• Evaluate the priorities for Argentina,
• Develop a practical five-year roadmap for species conservation,
• Strengthen cooperation between science, politics, and local communities.

Day 1 includes public lectures and a photo exhibition presenting research areas and local communities.
Day 2 focuses on an internal working session in which a concrete action plan for the recovery of the population will be developed.

Together, we are applying the IUCN One Plan Approach, which combines in situ and ex situ measures to secure the future of the Lahille dolphin, Tursiops truncatus gephyreus.

New study in LAJAM: Mercury in Guiana dolphins in Lake Maracaibo

sotalia guianensis dolphin delfin maracaibo lake venezuela lajam journal

A new study published in the Latin American Journal of Aquatic Mammals (LAJAM) reveals alarming mercury levels in dolphins and fish in Lake Maracaibo.

A recent study by Yurasi Briceño et al., supported by YAQU PACHA, has revealed alarming levels of mercury contamination in Guiana dolphins (Sotalia guianensis) and fish from the southern part of Lake Maracaibo in Venezuela.

Alarming results:
• Mercury was detected in all fish and dolphin samples tested.
• The WHO limit is 0.5 mg/kg.
• Four out of six dolphins significantly exceeded this value, one of them with 2.96 mg/kg.
• The fish species Gobioides broussonnetii also exceeded the limit value with 0.92 mg/kg.

Why this is important:
Mercury does not remain in the water, but enters the food chain from sediments to fish, dolphins, and ultimately humans.
These findings indicate a threat to marine wildlife and a serious risk to local communities that depend on fishing for their livelihood.

YAQU PACHA supports this research in order to raise awareness of the links between environmental pollution, species conservation, and human health.

The complete study was published in the Latin American Journal of Aquatic Mammals (Vol. 20, No. 2, 2025) .

YAQU PACHA has supported the publication of the LAJAM Journal from the very beginning.

Newsletter #2 on the GEPHYREUS Project published

bottlenose dolphin newsletter 2 dolphin project gephyreus

The second newsletter of the GEPHYREUS Project has been published and offers exciting insights into the ongoing research and conservation work for the Lahille's dolphin (Tursiops gephyreus) – a highly endangered coastal species that is only found in the waters of southern Brazil, Uruguay, and Argentina.

The project is carried out by our local partners and supported by YAQU PACHA and its partners, and is committed to protecting this unique dolphin population. In the new Gephyreus newsletter, you can learn more about current research activities, conservation measures, international collaborations, and educational projects that serve to preserve the species.

You can read Newsletter #2 as a PDF here:

English: [ENG] #2 Newsletter_Gephyreus_Project_final

Portuguese: [PT] #2 Newsletter – Projeto Gephyreus_final

Further information on the project can be found at: www.gephyreus.org

The Lahille dolphin – scientifically known as Tursiops gephyreus – lives in small groups in shallow coastal waters and river estuaries. It is known for its social behavior and close attachment to specific habitats. Unfortunately, the species is now one of the most endangered dolphin populations in the Atlantic. We currently estimate the total population to be 600 animals. Bycatch, pollution, and habitat loss threaten their survival, making international conservation initiatives such as Projeto GEPHYREUS all the more important.

YAQU PACHA at the Species Conservation Days in Duisburg, Düsseldorf, and Karlsruhe

species conservation days duisburg zoo aquazoo düsseldorf karlsruhe zoo yaqu pacha species conservation latin america south america

Once again this year, YAQU PACHA was represented with information stands at the Species Conservation Days at Duisburg Zoo, Aquazoo Düsseldorf, and Karlsruhe Zoo. Numerous visitors took the opportunity to find out more about our work and the situation of endangered aquatic mammals in South America and Mexico.

The focus was on our projects to protect La Plata dolphins (Pontoporia blainvillei), Lahille's bottlenose dolphins (Tursiops truncatus gephyreus), Amazon river dolphins (Inia geoffrensis), manatees (Trichechus inunguis), and the critically endangered vaquita (Phocoena sinus). Many guests were surprised to learn how severely these species are endangered by bycatch, habitat loss, and pollution—and how important international cooperation is in species conservation.

We were particularly delighted by the keen interest shown by families and children, who asked questions at our stands, took away information material, and enthusiastically chose our YAQU PACHA soft toys. By making a purchase, visitors directly support our projects—and at the same time take home a piece of species conservation.

The Species Conservation Days are a valuable platform for us to raise awareness of our projects, educate people about endangered species, and demonstrate that species conservation can only succeed if we work together. We would like to express our sincere gratitude to the teams at Duisburg Zoo, Aquazoo Düsseldorf, and Karlsruhe Zoo for the invitation and the excellent organization of these important events.

Many thanks also to the teams at the YAQU PACHA information stands:

Gephyreus Project – Progress in protecting the Lahille dolphin

project tursiops gephyreus projeto lahille bottlenose dolphin delfin delfine golfinhos delfines

The Gephyreus project is committed to the conservation of the highly endangered Lahille dolphin (Tursiops gephyreus). Since its inception, it has been supported by YAQU PACHA, Nuremberg Zoo, Zoomarine Portugal, Duisburg Zoo, Rancho Texas, and Heidelberg Zoo. The aim is to strengthen international cooperation and implement effective conservation measures.

A milestone was the launch of the official website www.gephyreus.org, which brings together scientific findings, the latest news, and events, thereby promoting transparency and public participation. Another highlight was the documentary film"Garbo,"which shows the unique collaboration between fishermen and dolphins in Laguna and highlights the importance of long-term local research.

The Gephyreus Network played a decisive role in the adoption of a trilateral conservation management plan (CMP) for the Lahille dolphin by the International Whaling Commission (IWC). Argentina, Brazil, and Uruguay are involved in this plan. The plan is based on four strategic pillars:
• Research
• Risk reduction
• Monitoring
• Public awareness & capacity building
A total of 24 conservation measures were established, seven of which are of the highest priority. At the same time, the network is working on reassessing the IUCN Red List status and on a proposal for Concerted Action under the CMS Convention on the Conservation of Migratory Species.

Important progress was also made in field research:
• Four fishing villages in southern Brazil were visited and 60 fishermen were interviewed about bycatch risks and fishing dynamics.
• Over 3,000 people were reached through training courses, school projects, and public events.
• Citizen science programs in Brazil (e.g., Araranguá, Tramandaí River) and Uruguay are getting the population more involved in conservation.

Coordinated photo identification surveys at over ten locations in Brazil and Uruguay, as well as the resumption of research in Bahía San Antonio (Argentina), provided valuable data—including 60,000 dorsal fin photos and 15 biopsies for pollutant analysis. A complete stock assessment is expected by 2026.

A new research project on skin changes in Lahille dolphins in Laguna and Patos Lagoon has also been launched. In view of increasing health risks, the project is developing a comprehensive dolphin health program.

Dr. Lorenzo von Fersen, Chairman of YAQU PACHA:
"The Lahille dolphin (Tursiops gephyreus) is one of the most endangered dolphin species worldwide. With Project Gephyreus, we are also implementing the IUCN One Plan Approach, which combines conservation measures in the field with cooperation in zoological institutions. Only by working together can we preserve this species in the long term."

7 months Francisca – Rescue of a Franciscana dolphin calf

francisca franciscana-dolphin brazil r3 animal 7 months dolphin dolphins golfinhos porpoise porpoises

On January 3, 2025, a newborn Franciscana dolphin calf was discovered stranded on a beach in Florianópolis, Brazil, and was named Francisca. She was alone, dehydrated, and severely weakened. Without immediate help, she would not have had a chance of survival.

Franciscana dolphins (Pontoporia blainvillei) are among the most endangered dolphin species in South America. Dolphin calves like Francisca are particularly dependent on their mothers during the first few months of life. When a calf like Francisca is found alone, it usually means certain death—but this time, everything turned out differently.

Francisca was immediately taken into the care of our project partner R3 Animal. There, a complex rescue process began: in the first few weeks, the dolphin calf was given special milk, monitored around the clock, and provided with medical care. Francisca was weak, but she fought – and she won.

Seven months later, it is clear how successful the rescue was: Francisca actively swims in a large pool, now eats fish independently, is playful, attentive, and very curious. The Franciscana dolphin calf has developed well physically, but still requires care, so release into the wild is not possible at this time.

francisca franciscana-dolphin brazil r3 animal 7 months dolphin dolphins golfinhos porpoise porpoises

Today, Francisca is a symbol and ambassador for her endangered dolphin species and an example of how dedicated species conservation saves lives.

R3 Animal ensures their care and long-term survival. YAQU PACHA supports R3 Animal in this endeavor and has been committed to protecting endangered marine mammals for over 30 years.

Let's give Francisca a future! Support Francisca and the rescue and rehabilitation efforts for all other stranded Franciscana dolphins with your donation.

Endangered whales and dolphins in South America: IWC conservation plans reviewed at workshop in Brazil

iwc workshop santos brazil brasil brasilien international whaling commission meeting cetaceans southamerica

From June 30 to July 5, 2025, more than 50 experts on whales and dolphins (cetaceans) met in Santos, Brazil. The aim of the workshop, organized by the Scientific Committee of the International Whaling Commission (IWC) and the Brazilian government, was to review and updateconservation managementplans (CMPs) for some of South America's most endangered species.

Among other things, the focus was on the southern right whale (Eubalaena australis), South American river dolphins (Inia geoffrensis, Sotalia fluviatilis), the Guiana dolphin (Sotalia guianensis), the Lahille bottlenose dolphin (Tursiops truncatus gephyreus), and the Franciscana dolphin (Pontoporia blainvillei).

Dr. Lorenzo von Fersen, Chairman of YAQU PACHA, participated in the workshop and emphasized his organization's commitment:

"This meeting was extremely important, as we not only evaluated progress but also spoke openly about the threats currently facing these cetaceans. Issues such as bycatch, climate-related events, and the increasing incidence of infectious diseases are particularly pressing. It is encouraging to see that we are working together on science-based solutions."
YAQU PACHA not only supported the workshop in terms of content, but was also one of the financial sponsors—a clear sign of the organization's strong commitment to the protection of endangered cetaceans in South America.

A particular highlight was the presentation of the Alliance for the Franciscana Conservation Research, Rescue, and Rehabilitation (AFCR3). Dr. Cristiane Kolesnikovas from R3 Animal gave a moving account of the caseof "Francisca,"a Franciscana dolphin currently undergoing rehabilitation—a symbol of the vulnerability and resilience of the species.

Dr. Alex Zerbini, former chair of the IWC Scientific Committee, praised the results:

"Workshops like this are essential. They bring together expertise, promote collaboration, and ensure that conservation plans remain living documents—continuously adapted to the latest scientific findings and best conservation practices."
YAQU PACHA's projects are significantly supported by zoological institutions such as Nuremberg Zoo, Duisburg Zoo, Heidelberg Zoo, Aquazoo Düsseldorf, Zoomarine Algarve, and Rancho Texas. These partnerships enable the One Plan Approach to be put into practice – an integrative species conservation approach in which measures in the natural habitat (in situ) and in human care (ex situ) are sensibly interlinked.

Red flag from Patagonia: Dolphins reveal hidden toll of human impacts

Habitat Anthropization Shapes the Skin Microbiome of Dolphins: A Red Flag About Health Chile

A groundbreaking study led by Cayetano Espinosa-Miranda (Yaqu Pacha Chile), supported by YAQU PACHA and Nuremberg Zoo, has revealed alarming evidence of environmental stress in dolphins off the Chilean coast of Patagonia. By analyzing the skin microbiomes of Chilean dolphins and Peale's dolphins, the researchers discovered that individuals living in areas heavily affected by aquaculture and urbanization show a striking loss of microbial diversity—replaced by opportunistic bacteria such as Vibrio and Halomonas.
These changes may be early warning signs of compromised health and indicate the hidden toll that human activities are taking on marine animals. The dolphin skin microbiome is proving to be a valuable, non-invasive indicator for monitoring the health of wild populations and the ecosystems they inhabit.

YAQU PACHA and Nuremberg Zoo are committed to supporting and expanding this important field of research. In order to protect endangered species and their habitats, we urgently need to intensify our efforts to monitor the health of the oceans through science.

Children collect donations for the vaquita

Class 4A Ober St. Veit Vienna Vaquita Donation Donations

Class 4A at the elementary school in Ober St. Veit near Vienna carried out a fantastic fundraising campaign over several weeks, collecting donations for the endangered vaquita and the YAQU PACHA rescue project. They raised an impressive total of €1,071. We would like to take this opportunity to thank class 4A for their wonderful support. The donation will be used specifically for the rescue and conservation of the vaquita in the Gulf of California in Mexico.
YAQU PACHA is working with Pesca ABC to establish alternative fishing methods that prevent vaquitas from ending up in nets. These alternative techniques are based on fishing with lines and hooks and provide fishermen with particularly good, high-quality fish. The method has been very well received and is gradually becoming established in the northern part of the Gulf of California, where the vaquita lives.
In addition, the Mexican government has sunk concrete blocks with steel hooks in the vaquita's habitat. This deters illegal fishermen from fishing in this area, as they would otherwise destroy their nets.
These two methods are intended to stabilize the vaquita population. We hope that we will see young animals again in the next population count. That would be a sign that the population is recovering. We currently estimate the total population to be 8–10 vaquitas.
Once again, a big thank you to class 4A and everyone who helped to raise this fantastic amount.
100% of the donations will go towards saving the vaquita and our species conservation project in collaboration with Pesca ABC.

A first meeting was recently held in Brazil to exchange experiences with local communities on the protection and management of the Amazonian manatee – Peixe Boi (Trichechus inunguis). The meeting was organized by the Fundación Natütama from Colombia, which has been successfully carrying out nature conservation work and environmental education with residents around Puerto Nariño (Amazonas, Colombia) for over 20 years.

The team at the Museu Paraense Emílio Goeldi research station in the Caxiuanã National Forest (Pará, Brazil) set out to learn from Natütama's many years of experience. Together with partners from ICMBio and the Instituto Bicho d'Água, they are currently caring for a young Amazonian manatee with the aim of releasing it back into the wild at a later date. During the meeting, experiences were shared, the region was explored, discussions were held with local communities, and a joint workshop was held to develop a long-term conservation program that actively involves the local population.

YAQU PACHA supports this important exchange, which aims to help establish sustainable conservation projects for Amazonian manatees – Peixe Boi – in Brazil and further expand the successful cooperation between scientists and the local population.

Four months that matter – the story of Francisca, the Franciscana dolphin calf

Francisca Franciscana dolphin calf Pontoporia blainvillei Toninha R3 Brazil

Since early January 2025, our partners at R3 Animal in Florianópolis, Brazil, have been caring for a special animal: Francisca, a weakened Franciscana dolphin calf that was found stranded on the coast on January 3.

Her chances of survival were initially slim—but with great dedication, an unprecedented rescue and rehabilitation effort began.
In the first few weeks, every hour was critical. Francisca had to be cared for around the clock, fed special milk, and medically stabilized. Thanks to the dedicated team on site, she continued to develop steadily—step by step.

Today, four months later, she has developed into a strong, curious young animal. She eats fish and shrimp independently, displays natural diving behavior, and has been living in a larger tank for some time now, which gives her more space to move around and develop further.

This project is unique worldwide: never before has a stranded Franciscana dolphin (Pontoporia blainvillei) been successfully cared for over such a long period of time. Francisca is therefore not only a symbol of hope for her species—she is a milestone for the protection of marine mammals in South America.

For over 25 years, YAQU PACHA has been committed to the conservation of the Franciscana dolphin – one of the most endangered dolphin species in the world. Together with R3 Animal, Nuremberg Zoo, the National Marine Mammal Foundation, and Dolphin Quest, we have founded the Alliance for Franciscana Dolphin Conservation Research, Rescue, and Rehabilitation (AFCR3). Supported by Zoomarine Algarve, Portugal. This international alliance combines research, conservation, and rehabilitation work—and Francisca is at the heart of this mission.

Caring for and feeding a dolphin calf like Francisca is extremely costly—around €200 per day is needed for food, medical care, and supervision.
Your help makes a difference: with your donation, you are not only enabling Francisca to continue to develop, but also strengthening the protection of her entire species.

Findings & Public Relations in the Farol das Baleias Project

farol das baleias baleia whale right whales smooth-sided whales

The 2024 field season of the Farol das Baleias project yielded significant findings on the ecology, health, and behavior of southern right whales (Eubalaena australis) in southern Brazil. Over 106 days, 420 drone flights were conducted, providing 120 hours of observation time and 45 hours of video footage. A total of 246 individual whales were identified, including 26 re-encounters from previous years – an indication of their site fidelity.

Drone photogrammetry was used to document the physical condition of 41 lactating females and 56 calves. Observations showed that mother-calf pairs spend about 10% of their time engaging in social interactions. Six cases of entanglement in fishing gear were recorded, but all right whales were later sighted free again – proof of the importance of monitoring and protective measures.

The Farol das Baleias project also placed great emphasis on public relations: educational activities with interactive formats and citizen science took place in Torres. Participation in international conferences promoted scientific networking. Publications, a new doctoral project, and the first "Whale Festival of Torres" are planned for 2025.

YAQU PACHA Annual General Meeting 2025

yaqu pacha annual general meeting annual meeting nuremberg members membership

On Friday, March 28, 2025, YAQU PACHA held its annual general meeting, to which both YAQU PACHA members and representatives of our partner organizations were invited to report on important conservation initiatives in Latin America that are supported—and in some cases also coordinated—by YAQU PACHA.

The first speaker, Dr. Thais Carneiro Rodrigues, reported on the rescue and rehabilitation of Francisca, a Franciscana dolphin calf(Pontoporia blainvillei), who is currently being cared for at r3 in Brazil. Dr. Magdalena Arias then provided insights into efforts to protect Lahille's bottlenose dolphins (Tursiops gephyreus) in Argentina. Dr. Enrique Sanjurjo from Pesca ABC concluded the presentations with a compelling overview of their work to introduce alternative fishing methods to protect the last remaining vaquitas (Phocoena sinus).

Dr. Lorenzo von Fersen then gave a comprehensive overview of YAQU PACHA's current projects throughout Latin America and presented some of our initiatives in Europe in the past year 2024.

In accordance with our statutes, the election of the board was due. Three members were confirmed in their positions and we are pleased to welcome a familiar face as our new secretary:
Stefan Wiessmeyer, a long-time friend of the organization, who previously served as 2nd chairman for many years.
The new Executive Board was unanimously elected as follows:
– Dr. Lorenzo von Fersen – First Chair
– Sandra Honigs – Second Chair
– Martina Hofer – Treasurer
– Stefan Wiessmeyer – Secretary

We would also like to express our heartfelt thanks to Henning Plückebaum, who has stepped down after an incredible 11 years as secretary.

Francisca – a ray of hope for the protection of Franciscana dolphins

frnancisca franciscana dolphins toninha la plata dolphin brazil meeting brazil r3 animal

Francisca, the Franciscana dolphin calf, has been in the care of R3 in Brazil for several weeks now and is growing and thriving. For some time now, Francisca has also been fed shrimp and small fish, and she has already learned to search for and eat them on her own.
Dr. Lorenzo von Fersen attended a meeting in Brazil to discuss Francisca's future. The trip was made possible by the support of Nuremberg Zoo. In the near future, Francisca will also be moved to a larger tank, and the keepers will continue to care for her around the clock. Let's keep our fingers crossed for Francisca's healthy development.
We are still dependent on your donations and support to care for Francisca, and we appreciate any help. Thank you very much!

Help for Francisca, an endangered Franciscana dolphin

Innovative solution against bycatch wins award at SMM conference

award federico sucunza science on a shoestring smm perth australia gemars projeto pesca

Dr. Federico Sucunza from GEMARS, a partner NGO of YAQU PACHA from Brazil, was awarded the Science on a Shoestring Award at the recent Society for Marine Mammalogy conference in Perth, Australia. This award recognizes groundbreaking, low-cost ideas with a big impact on marine conservation.
Dr. Sucunza's initiative, called Projeto PESCA, focuses on reducing bycatch through sustainable and innovative methods. His solution involves attaching empty PET bottles to fishing nets to create a sound barrier that allows dolphins and other marine mammals to detect and avoid the nets. Field trials have shown an impressive reduction in bycatch, making this approach a game changer for marine conservation.

Since the beginning of Projeto PESCA, YAQU PACHA, Nuremberg Zoo, and ZOOMARINE – Algarve have been important partners, contributing to the project's success with their support and expertise. This collaboration underscores the importance of partnerships in effectively addressing global conservation challenges.

In addition to receiving the award, Dr. Sucunza was selected to participate in a prestigious panel discussion, where he shared insights into the development and implementation of this cost-effective and impactful solution. His work highlights the power of community-driven innovation and partnerships that advance marine conservation.

YAQU PACHA, Nuremberg Zoo, and ZOOMARINE Algarve congratulate Dr. Sucunza and GEMARS on this award and remarkable achievement, and will continue to support Projeto PESCA in its mission to protect marine biodiversity.

Franciscana Dolphin: Workshop on rescue and rehabilitation

toninha workshop brazil franciscana dolphin

Ubatuba, Brazil – From November 8 to 10, the Alliance for the Franciscana Dolphin Conservation Research, Rescue and Rehabilitation (AFCR3) held a groundbreaking workshop at the Instituto Argonauta to advance conservation efforts for the Franciscana dolphin (Pontoporia blainvillei). Led by Dr. Jenny Meegan of the National Marine Mammal Foundation (NMMF), USA, and Dr. Aricia Benvenuto of the University of São Paulo, Brazil, 24 participants from various Brazilian institutions came together to discuss basic rehabilitation techniques and standardized necropsy protocols.

The workshop focused on two critical needs: the rehabilitation of stranded Franciscana dolphins, from newborns to adults, and the ability to perform standardized necropsies to identify threats and causes of death. The training was based on scientifically sound protocols developed by the Alliance, a collaborative network of over 34 veterinarians, biologists, nutritionists, and zootechnicians from Argentina, Uruguay, Brazil, the US, Spain, and Germany.

Urgent need for action

The Franciscana dolphin is classified as endangered on the IUCN Red List of Threatened Species due to widespread threats such as bycatch, habitat loss, and pollution. In Brazil, however, the species is even more endangered and is listed as Critically Endangered (CR) on the country's national Red List. The high number of strandings underscores the urgent need for qualified rehabilitation measures, while necropsy data is essential to understand and address the causes of mortality.

"Workshops like this are not just about saving individual animals, but about securing the future of a species," says Dr. Jenny Meegan. "From our perspective, this is an opportunity to combine global expertise with local conditions. Collaborations like this allow us to share advanced veterinary techniques and rehabilitation protocols developed at the international level and ensure that this knowledge is available to those who need it most. Protecting the Franciscana dolphin is a global task, and every effort, no matter who it comes from, contributes to the survival of this species. The NMMF has learned a lot by working with conservation teams in other countries, and we are honored to support the incredible work being done here in Brazil.

Dr. Aricia Benvenuto emphasized the local perspective: "In Brazil, the Franciscana dolphin is an important part of our marine biodiversity, and its endangered status is a call to action for all of us. This workshop is crucial because it provides local professionals with the tools and knowledge they need to respond effectively to strandings and perform meaningful necropsies. Strengthening Brazil's capacity to rescue and protect marine mammals is critical to the survival of this species. As someone who works directly with the marine ecosystems where these dolphins live, I see the urgent need for collaborative efforts like this. Together, we can ensure that conservation remains not just a concept, but is put into practice in the regions where it is most needed.

Why this workshop is important:

Allianz's commitment to preserving the Franciscana dolphin depends on a multi-faceted approach, and this workshop is an example of its goals:

  • Improving rehabilitation success: The training enables participants to provide professional care for stranded dolphins, thereby increasing their chances of survival.
  • Sound conservation strategies: Standardized necropsies provide important data for combating anthropogenic threats, from fishing practices to environmental toxins.
  • Global cooperation: The workshop underscores the Alliance's commitment to cross-border knowledge exchange and the promotion of international cooperation for species conservation.

About the alliance

The AFCR3 was founded in 2019 with the aim of providing assistance during strandings, supplying important equipment and expertise, and empowering conservationists through training. Founding members YAQU PACHA and Nuremberg Zoo coordinate the alliance's activities with other institutions and drive forward the mission to protect the Franciscana. Many non-governmental organizations and universities from South America, such as Fundación Mundo Marino & Aquarium (Argentina), Karumbé & RENACE (Uruguay), Univ. of São Paulo, Biopesca, Univ. do Estado de Santa Catarina, Univ. Federal do Paraná, CRAM, R3, Aiuká, UNIVILLE, Inst. Gremar, and Inst. Argonauta (all from Brazil), are active members of this alliance. In addition, organizations such as the National Marine Mammal Foundation (NMMF) and Dolphin Quest from the USA, as well as L'Oceanogràfic, Nuremberg Zoo, YAQU PACHA, and ZOOMARINE – Algarve from Europe are providing crucial support for this initiative. This diverse coalition underscores the importance of global cooperation in securing the future of the Franciscana dolphin.

Dr. Lorenzo von Fersen, Chairman of YAQU PACHA, emphasized the organization's long-standing commitment: "YAQU PACHA has been focusing on the protection of the Franciscana dolphin for almost 26 years. One of our main goals is to strengthen the capacities of local experts and institutions and ensure that they are equipped with the necessary tools and knowledge to protect this remarkable species. Collaboration and education are at the heart of our work, and this workshop is a testament to these values.

The success of the workshop was greatly supported by Instituto Argonauta, whose team provided exceptional logistical and technical assistance. Their commitment to marine conservation and practical experience in dealing with stranded marine mammals made them an invaluable partner in this event.

This workshop is a crucial step toward building a bridge between science and practice and securing the future of one of the world's most endangered dolphin species.

Sobering prospects: The future of species conservation is at stake

cop16 fernando trujillo omacha inia sotalia biodiversity species conservation future

The results of the recent COP16 biodiversity conference are disappointing. Individual countries are unwilling to invest in the conservation of biological diversity and the protection of endangered species. Dr. Fernando Trujillo from our partner organization Fundación Omacha was on site in Cali, Colombia, and reports on an alarming shift in global priorities that is making it increasingly difficult to gain much-needed support for the protection of endangered species and their habitats.

Despite these challenges, we remain determined and continue our work in close cooperation with partner organizations in Latin America. Regular exchange and joining forces are the key to success in species conservation.

Your support remains indispensable in this endeavor. Together, we can save endangered aquatic mammal species from extinction. We thank you from the bottom of our hearts—today and in the future.

Manatee workshop in Icapuí, Brazil: Protecting Caribbean manatees

manatee workshop manati brasil brazil alliance for manatees lorenzo von fersen

Icapuí, Brazil – From October 14 to 17, the Oh Linda! Pousada in Icapuí, Brazil, hosted an important Alliance for Manatees workshop that brought together experts from across South America to discuss the urgent conservation needs of Caribbean manatees. A total of 23 dedicated experts from 19 leading institutions and six South American countries, from Brazil to Colombia, took part. It was the first time such an international meeting had been held in South America.

This groundbreaking workshop was an important step toward protecting the manatee. Over four days, lively discussions were held, current scientific data on manatee habitats was evaluated, existing threats and conservation priorities were assessed, and future measures were developed. A key goal of the event was to refine habitat maps and identify critical areas that need immediate protection.

Caribbean manatees are gentle, slow-swimming marine mammals known for their round, bearded faces and paddle-shaped tails. Often called "sea cows," they live mainly in shallow coastal waters, estuaries, and inland waters of South America. They play an important role in their ecosystems by grazing on aquatic plants, thereby improving water quality. Unfortunately, the South American subspecies, the Caribbean manatee (Trichechus manatus manatus), is classified as "endangered" by the IUCN due to threats such as habitat loss, boat accidents, and climate change. Their survival depends critically on active conservation measures that secure their habitat and control human impacts.

Dr. Carol Meirelles, manatee expert and research associate at the Marine Mammal Research Unit (MMRU) at the University of British Columbia, organized and led the workshop. "The workshop brought together experts with direct data and information that had never been shared before," said Dr. Meirelles. "This allowed us to determine where manatees still occur and where they are threatened."

Professor Andrew Trites, Director of the MMRU, also made an important contribution to the workshop's leadership. His expertise in moderating discussions fostered the spirit of cooperation that made the event such a success. "It was truly remarkable," says Trites, "to see such a diverse group of manatee experts from across South America in one place and to witness how necessary it is for them to speak with one voice to protect the manatees in their home countries."

The alliance focuses on manatees in Colombia, Venezuela, Guyana, Suriname, French Guiana, and Brazil—regions where five national languages are spoken and environmental protection varies in intensity. "Caribbean manatees do not belong to any one country," says Trites. "They are a shared responsibility for all of South America. All countries where manatees are found must work together to ensure their survival."

The protection of manatees is not only a top priority in South America. Partners such as the Pairi Daiza Foundation in Belgium, Nuremberg Zoo in Germany, and YAQU PACHA in Germany also consider the protection of manatees to be of great importance, which is why both provided financial support to make the workshop possible. "We wanted to contribute to the long-term protection of manatees and are proud to support the Alliance's efforts," said Dr. Catherine Vancsok, scientific director of the Pairi Daiza Foundation and one of the main sponsors of the workshop. Dr. Lorenzo von Fersen, Curator for Research and Species Conservation at Nuremberg Zoo and Chairman of YAQU PACHA e.V., emphasized the responsibility of European institutions to actively contribute to the protection of manatee populations.

"As coordinator of the Manati EEP (EAZA Ex-situ Program) of the European Association of Zoos and Aquariums (EAZA), we see supporting the Alliance for Manatees as a unique opportunity to pool our knowledge and resources to ensure the long-term survival of manatees," said von Fersen. The involvement of zoos underscores the importance of the IUCN One Plan Approach as a holistic strategy for species conservation. "Zoo-based research provides important data on health, behavior, and reproduction that benefits wild populations and underscores the critical role of ex-situ species conservation."

Von Fersen praised the strong commitment of all those involved: "What particularly impressed me was the willingness of many participants to share their data and knowledge for a common goal. This open collaboration and exchange of knowledge is exactly what we need for effective conservation strategies. It strengthens my confidence that together we can make a real contribution to the conservation of this endangered species."

Dr. Meirelles will use the valuable insights gained from the workshop to update the current manatee habitat maps so that they can continue to serve as a basis for the protection of this species. The international team of manatee experts will continue to collaborate in online meetings over the coming months to create a comprehensive priority map for manatee conservation in South America.

In addition to the intensive discussions during the Manati Workshop, participants also had the opportunity to visit local rehabilitation centers, including the Aquasis Rehabilitation Center and the Praia da Peroba Release Center in Icapuí. These visits provided valuable insights into the practical conservation measures being taken to preserve the region's endangered manatee populations.

The Manati Workshop was made possible thanks to logistical support from Aquasis, a Brazilian non-profit organization dedicated to marine conservation. The Alliance for Manatees is a project of the Marine Mammal Research Unit at the Institute for the Oceans and Fisheries at the University of British Columbia and is supported by various partners, including Nuremberg Zoo, the Pairi Daiza Foundation, YAQU PACHA e.V., and the IUCN Species Survival Commission.

With continued support from these organizations and the dedication of manatee researchers, the Alliance for Manatees is poised to make significant progress in protecting this iconic species throughout South America.

"The willingness to cooperate and share data and knowledge demonstrated this week gives me hope that, if we join forces and speak with one voice, we can ultimately save the manatees throughout their entire habitat," said Meirelles.

Protection of the Caribbean manatee: Important workshop in Brazil

workshop Caribbean manatee manatees manatis Brazil Alliance for Manatees

Fortaleza/Icapui, Brazil – The Alliance for Manatees, a flagship project of the Marine Mammal Research Unit at the Institute for the Oceans and Fisheries at the University of British Columbia, is currently hosting an important workshop in Brazil to strengthen the protection of the endangered Caribbean manatee (Trichechus manatus). Coordinated by Dr. Carol Meirelles, a research associate at UBC, and Prof. Andrew Trites, director of the Marine Mammal Research Unit, the workshop is taking place in Fortaleza from October 14 to 18 and brings together leading researchers from across Latin America.

Working together for species conservation

Twenty-three researchers from 18 institutions in Brazil, Venezuela, Mexico, Suriname, French Guiana, and Colombia are participating in the workshop. The experts are working to refine habitat models and create a priority list for the protection of manatees, which are threatened by habitat destruction and climate change. The meeting marks a crucial moment for species conservation efforts in the region, with a particular focus on identifying critical habitats and the most effective strategies for their protection.

The week-long event also provides researchers, who have been collaborating virtually over the past year, with an opportunity to validate their findings and agree on conservation priorities. Logistics for the event are being supported by Aquasis, a local NGO dedicated to species conservation.

Dr. Lorenzo von Fersen, Curator for Research and Species Conservation at Nuremberg Zoo and Chairman of YAQU PACHA e.V., took part in this important meeting. He presented the IUCN One Plan Approach and the EAZA Manati EEP (EAZA ExSitu Program) to the participants.

During the workshop, Dr. von Fersen emphasized: "
" "Species conservation, as in the case of manatees, requires a holistic approach. It is important to strengthen in situ initiatives. At the same time, it is important to involve zoos in this process, as they can fulfill very important ex situ tasks. These include raising awareness among visitors, carrying out research projects that are only possible under controlled conditions, and, last but not least, financing in situ projects. This is precisely the holistic approach pursued by the EAZA Manati EEP, and as coordinator of this EEP, I present convincing arguments to encourage the member zoos of the EEP to become more involved and active. Species conservation can only be successful if all stakeholders are part of the process."

About the Alliance for Manatees

The Alliance for Manatees, coordinated by Dr. Carol Meirelles, is part of the Marine Mammal Research Unit at UBC, led by Prof. Andrew Trites. The project brings together leading institutions from across Latin America to protect Caribbean manatees and their habitats. It is supported by major funders such as Nuremberg Zoo, the Pairi Daiza Foundation, YAQU PACHA e.V., and IUCN Species Survival.

Workshop location: The workshop will take place in Icapuí, Ceará, a coastal town that offers participants an inspiring environment in which to work together on important initiatives to protect the Caribbean manatee.

Endocrine assessment of southern right whales: A multidisciplinary approach

southern right whale Eubalaena australis

With the support of Nuremberg Zoo, we are conducting a multidisciplinary study together with our partners to investigate the endocrine responses of southern right whales (Eubalaena australis) to various influences, such as changes in food quality and availability, attacks and harassment by seagulls, injuries from fishing nets and collisions, and ship traffic. To do this, we measure hormones that indicate stress response (glucocorticoids) in adipose tissue biopsies and use aerial photographs taken by drones to assess physical condition and the presence of injuries and to identify the animals. By integrating these methods, we aim to understand how various human and environmental influences affect the health and well-being of whales.
The project is led by researchers from the Instituto de Conservación de Ballenas, the Marine Mammal Laboratory ofthe Centro para el Estudio de Sistemas Marinos (CESIMAR-CONICET), and the Instituto de Investigaciones en Ciencias de la Salud (INICSA-CONICET).
During the 2024 season, we have sampled more than 120 individual southern right whales, including mothers with calves, adults, and juveniles, and taken more than 6,000 aerial photographs. And this is just the beginning!
The aim of the project is to better understand the physiology of whales in order to obtain important information for the protection of these incredible marine mammals and the marine environment. We remain committed to the protection of whales, both regionally and globally!

Recurring drought threatens Amazon river dolphins: A growing crisis

Lake Tefé river dolphins Amazon dolphin tucuxi sotalia rescue

TEFÉ, Brazil – As smoke from thousands of forest fires rises above the Amazon basin, researcher Miriam Marmontel from the Mamirauá Institute for Sustainable Development is becoming increasingly concerned. Brazil is experiencing the worst drought in its history, and conditions are similar to last year's devastating events. Water levels in the Amazon basin have fallen to record lows, and temperatures are approaching the levels that led to the mass death of endangered river dolphins a year ago.

In 2023, water temperatures in Lake Tefé reached an alarming 39.6°C, leading to the death of freshwater dolphins. This year, the situation has worsened: the drought arrived earlier than usual and the water level dropped by up to 30 centimeters per day. Although rainfall and smoke have temporarily lowered temperatures, Marmontel and her team fear that we are on the verge of a similar or even worse disaster.

The Amazon is home to the Amazon river dolphin (boto) and the tucuxi, both of which are threatened with extinction. Prolonged drought, exacerbated by climate change, has already led to mass deaths. The death of over 200 dolphins around Tefé last year and further deaths downstream highlight the ongoing crisis. Recent discoveries of dead dolphins showing signs of human impact underscore the growing tensions between dolphins and local fishermen, exacerbated by falling water levels.

Marmontel, who has been working closely with YAQU PACHA for years, emphasizes the ongoing urgency of the situation. Last year, YAQU PACHA played a central role in coordinating rescue operations for the dolphins. This year, YAQU PACHA is in constant contact with colleagues on the ground. Together with her team, Marmontel is actively monitoring the health of the dolphins and preparing for future deaths. However, the repeated extreme conditions suggest that such events could become the new normal. The Mamirauá Institute is improving its rescue capabilities and securing the support of the Brazilian military and private organizations to address this growing crisis.

The repeated occurrence of such extreme droughts underscores the urgent need for global action to combat climate change and protect these critical species. As indicator species, dolphins point to larger environmental problems that require immediate and sustained attention.

You can support us in saving river dolphins with your donation.

Dolphin models by Piotr Przylucki

Vaquita, bottlenose dolphins, and La Plata dolphins—all of these small whale species are critically endangered and threatened with extinction.
To raise awareness of this issue, we held a species conservation week focusing on endangered whales and dolphins at Nuremberg Zoo from July 1 to 7. In our permanent exhibition, you can learn about various endangered small whale species through models.

sea of shadows vaquita vaquitas

On Saturday, as part of Species Conservation Week, we screened the documentary "Sea of Shadows," which is about saving the last vaquitas. In this context, Dr. Lorenzo von Fersen (1st Chairman of YAQU PACHA e.V.) spoke about the threat to small whale species and presented our conservation projects.
The vaquita (Phocoena sinus), also known as the California porpoise, is the most endangered marine mammal in the world. It is estimated that there are only about 9 vaquitas left. Through educational work, strict enforcement of fishing regulations, and the promotion of sustainable fishing practices, YAQU PACHA is helping to preserve the vaquita's habitat in the Gulf of California.

In addition to the problem of bycatch, climate change is one of the greatest threats to whales and dolphins.
The children's and youth group of the Nuremberg Zoo Friends Association, the TierEntdecker (Animal Explorers), prepared an exhibition on these topics and informed visitors about these important issues. We would like to take this opportunity to express our sincere thanks to the TierEntdecker for their great work and fantastic support during our Species Conservation Week at Nuremberg Zoo.

Vaquita protection together with Pesca ABC

YAQU PACHA, Nuremberg Zoo, and Zoomarine Portugal are pleased to announce their continued support for Pesca ABC.
Pesca ABC is a grassroots organization led by local fishermen and women that promotes sustainable fishing in the northern Gulf of California, Mexico.
The vaquita (Phocoena sinus) is the most endangered marine mammal in the world. The main cause of its decline is mortality from fishing nets used in both legal and illegal fishing. We are working with Pesca ABC to promote alternative fishing methods to gillnets in order to save the vaquita from extinction while preserving local livelihoods.

fishing abc vaquita fishing rescue

Hook and line fishing is a proven sustainable method that allows fishermen to do their work while protecting the vaquita. Drift nets are the main cause of the decline in the vaquita population. Fish caught in gillnets arrive dead and crushed, while fish caught with hooks and lines arrive alive. The use of humane post-harvest processing techniques improves the quality, shelf life, and price of the fish. Better prices are key to encouraging fishers to abandon gillnets in favor of hooks and lines. We are supporting Pesca ABC in building local capacity to implement a Japanese humane technique known as Ike-Jime.

With support from YAQU PACHA and other donors, Pesca ABC has developed a catalog of techniques that do not require gillnets, in order to secure livelihoods and save the vaquita from extinction. In the coming months, Pesca ABC will also collaborate with Mujeres Acuicolas del Mar de Cortés to establish an oyster farm as an alternative to gillnets. In addition, Pesca ABC is working closely with a group of women who catch squid during the tidal season. By supporting these and other gillnet-free fishing methods, Pesca ABC is helping to save the vaquita.

Vaquita Expedition 2024: Findings and Challenges

The Vaquita Expedition 2024, involving numerous experienced researchers, took place between May 5 and 26. The study area covered the Zero Tolerance Zone (ZTZ) and a new Extension Zone (EZ). This year, 9 vaquitas were sighted, fewer than last year (16), but acoustic encounters increased from 61 to 70. The lower number of sightings in the ZTZ does not necessarily mean that the population is declining, as this is only a small part of their range.
The observers who conducted the expert survey did not see any calves, although one yearling vaquita was sighted. They believe that there are likely to be 6 to 8 vaquitas remaining in 2024, with a lower probability of 9 to 11.
This estimate is lower than the 8 to 13 vaquitas sighted in the same area last year. However, all vaquitas sighted in 2024 appeared to be healthy.

One of the highlights of the Vaquita Expedition was a new, unique video featuring unprecedented drone footage. These innovative images offer an unprecedented view of the vaquitas.

Dr. Barbara Taylor, who led the expedition, explained: "While these results are concerning, the area surveyed represents only 12% of the total range where vaquitas were observed in 2015. Since vaquitas move freely within the vaquita sanctuary, we need to expand our research using acoustic tracking to find out where they are moving. Vaquitas outside the sanctuary, which is protected by concrete blocks with hooks, need protection from gillnets, which are their only threat."
YAQU PACHA has been working for several years to protect the vaquitas locally, but also raises awareness in Europe about the fate of the species through targeted campaigns.

River dolphin project in Venezuela – Current measures

inia geoffrensis venezuela sotalia project river dolphins

Last year, we launched PROYECTO SOTALIA, a project to track the distribution of river dolphins (Inia geoffrensis) in Venezuela using satellite transmitters. The aim of the project is to obtain information about the animals' movements and identify priority areas for this species in order to develop specific conservation measures.

As a result of climate change, periods of rain and drought have led to an increase in river dolphin strandings. For this reason, we have begun training local stakeholders and employees of environmental institutions (capacity building) this year so that they can respond efficiently to these events in order to reduce the mortality rate of this endangered species.

We were able to hold a training workshop at the El Hato El Cedral facilities in the state of Apure. In this region of the Venezuelan lowlands, there are increasing reports of strandings during the summer season. The event therefore provided an opportunity to exchange experiences and provide appropriate tools to respond to these situations, which could increase due to climate change.

Environment Week in Brazil

environment week brazil environmental week brazil human ecology of the ocean

During National Environment Week in Brazil, our partners from ECOLOGIA HUMANA DO OCEANO at the Federal University of Espírito Santo carried out activities with children and visitors. During this week, the environmental education fair took place in the municipality of Guarapari in the state of Espírito Santo in southeastern Brazil, where our research was presented in a scientific exhibition. During Environment Week, our partners organized games, videos, lectures, and educational activities about the Franciscana or Toninha dolphin (Pontoporia blainvillei) and the Sotalia dolphin (Sotalia guianensis), which are found in this region of the country.
The project presented is a partnership between ECOLOGIA HUMANA DO OCEANO, fishing communities, and schools.
YAQU PACHA has been supporting projects like this for several years. Collaboration in environmental education is important to inform society about anthropogenic influences on dolphins.

Human Dimensions of Small Cetacean Conservation group group photo

We are pleased to share with you the results of the workshop on the human dimensions of small whale conservation, which took place in Nuremberg in December 2022. Our main goal was to examine the influence of human behavior, thinking, and feelings on efforts to protect small whales. We discussed future challenges and opportunities and emphasized the importance of involving local communities and stakeholders.

It is clear that a holistic approach that takes social, economic, cultural, and political factors into account is crucial. Collaboration is key! We must work hand in hand with conservation organizations, governments, and local communities, adapting our strategies to changing needs and perspectives. Let us remember our key messages: Understanding human behavior is crucial to reducing impacts on the marine environment. Successful conservation requires a change in human behavior, and our efforts must benefit both dolphins and human communities.

Effects of whale watching on the behavior of right whales

smooth-sided whales brazil caipora instituto baleia franca

This study includes an assessment of the impact of whale watching on the behavior of the southern right whale (Eubalaena australis) and provides compelling evidence that this activity requires careful monitoring and regulation. The research conducted within the APA da Baleia Franca/ICMBio marine protected area and supported by YAQU PACHA e.V. has provided invaluable insights that underscore the need for sustainable tourism practices.

Whale watching is a popular ecotourism activity, but it has been shown to have a significant impact on whale behavior and welfare when not managed properly. Through careful observation and data collection, this study examined the effects of whale watching boats on various aspects of whale behavior. Modern tracking technologies and behavioral analysis methods were used to quantify the extent of human disturbance to the natural behavior of these marine mammals.

The conclusive results of this assessment serve as an important basis for informed decisions regarding tourism management in the APA da Baleia Franca/ICMBio marine protected area. It is imperative that stakeholders use this knowledge to implement targeted remedial measures aimed at minimizing disturbance to southern right whales while providing an enriching experience for tourists.

This research makes an important contribution to the overarching goal of promoting sustainable coexistence between human activities and marine ecosystems. By recognizing the impact of whale watching and applying responsible management strategies, we can not only seek to protect whales, but also create new opportunities for the people who live in this area and must coexist with wildlife. In this way, we can preserve both biodiversity and the future of human populations.

The results of this project will be incorporated into the master's thesis of Daiane Manholer dos Santos, which is currently being conducted at the State University of Maringá (UEM), Brazil. The project was supervised by Jonatas Prado and Arturo Andriolo.

PESCA ABC fish guide for the protection of the vaquita

fish guide pesca abc golf of California vaquita

PESCA ABC, in collaboration with YAQU PACHA and other institutions, has taken an important step toward protecting marine fauna by publishing a fish guide that reflects our commitment to sustainability and environmental protection. This fish guide is not only a compilation of species, but also a testament to our efforts to conserve marine resources in a responsible and ethical manner.
One of the most outstanding features of this catalog is that all the fish it contains come from selective and sustainable fishing methods. In an area where the Vaquita is fighting for survival due to the use of gillnets, has PESCA ABC committed to not using this method, which carries a high risk of bycatch. Instead, selective fishing techniques have been chosen that minimize the impact on unwanted species and ensure the protection of endangered marine animals.
The catalog also reflects the inclusivity and gender equality in our community. Both men and women are actively involved in all stages of the process, from catching to marketing. We recognize and value the contribution of each individual, regardless of gender, to the preservation of our natural resources.
To ensure compliance with the regulations on Protection of the vaquitaTo ensure the protection of endangered species, such as sea turtles and non-target species, the catalog is supported by certifications that confirm a commitment to responsible fishing practices. Last but not least, we promote the use of the Japanese IKE-JIME technique for the humane killing of fish in the catalog. This quick and humane method guarantees the quality and freshness of the fish while respecting animal welfare. With the introduction of this technique, we reaffirm our commitment to ethical principles in all phases of fishing activities.
In short, the launch of this fish catalog is not just an event, but an important milestone in our fight to protect the oceans. It is an expression of our shared commitment to sustainability, gender equality, compliance with regulations, and respect for all marine life. We invite everyone to join us on the journey toward a future where we can enjoy the riches of the sea without compromising its integrity.

Lahille Dolphin Workshop in Brazil

lahille dolphin workshop brazil bottlenose dolphin brazil

Two weeks ago, an important workshop was held to develop a Conservation Management Plan (CMP) for the Lahille bottlenose dolphin. Organized by KAOSA, the workshop was attended by numerous stakeholders, including scientists, conservationists, and government representatives, and was a crucial step toward ensuring the long-term survival of this endangered dolphin species.

For two days, participants engaged in intensive discussions, data analysis, and joint planning sessions. The workshop began with comprehensive presentations on the current status of Lahille's bottlenose dolphin populations, their conservation status, and the various threats they face, including habitat destruction, pollution, and bycatch.
The workshop ended with a sense of optimism and a renewed commitment to joint conservation efforts. As the draft CMP will be further refined and consulted on in the coming months, the workshop is a testament to the power of international cooperation. YAQU PACHA, as an NGO, strongly supports this CMP and is already involved in the implementation of several projects that we have set out in the five-year action plan.

Vaquita: perfectly blocked!

Nuremberg Zoo draws attention to the situation of the vaquitas with this installation.

Creative approach to species conservation
In 2023, a groundbreaking step was taken in the fight against illegal fishing. The introduction of innovative concrete blocks with steel hooks in the habitat of the endangered vaquitas effectively trapped fishing nets and reduced their deadly impact on the species. This step marks a turning point in the protection of vaquitas, as illegal fishing declined by around 90 percent for the first time. There is renewed hope for the future of the endangered vaquitas in the Gulf of California.
This innovative method not only protects the vaquitas, but also sets a global example: creative approaches and cooperation can produce effective solutions to complex environmental problems.

Five-year conservation strategy for the Lahille bottlenose dolphin

lahille's bottlenose dolphin action plan lahille bottlenose dolphin tursiops gephyreus

Preserving biodiversity remains an urgent imperative for the health of our planet. With the increasing challenges posed by human-induced problems, the conservation of each individual species is becoming a critical priority. The Lahille bottlenose dolphin(Tursiops gephyreus), of which there are only a maximum of 600 remaining, faces increasing threats from habitat destruction, pollution, bycatch, and climate change, highlighting the urgent need for concerted conservation efforts.

In view of the endangered status of the Lahille's bottlenose dolphin, YAQU PACHA and Nuremberg Zoo, together with theGephyreus Working Group from Brazil, have initiated a strategic measure that was published just a few days ago. The aim of this collaboration was to set research priorities and coordinate conservation measures to ensure the survival of the species.

The comprehensive strategy, which follows the recommendations of the Integrated Conservation Planning for Cetaceans (ICPC), is the result of extensive consultations, reviews, and expert contributions. Five strategic areas have been identified: (1) scientific research and conservation, (2) legislation and policy, (3) communication, public relations, and awareness raising, (4) institutional strengthening and education, and (5) citizen science.

After careful consideration, the researchers compiled a portfolio of projects that align with each strategic line, taking into account factors such as feasibility, impact, and stakeholder involvement. Of the 26 key projects, eight were identified as high priority, reflecting the strategic focus on initiatives with the potential for significant impact on nature conservation.

This 5-year strategic plan underscores the commitment to addressing the multiple challenges facing the Lahille bottlenose dolphins. By promoting international cooperation, strengthening stakeholder engagement, and setting priorities for targeted actions, stakeholders remain steadfast in their determination to protect this highly endangered species.

"This document is the most important basis for a well-thought-out conservation strategy, and if we succeed in implementing the various projects, we can be sure that the Lahille bottlenose dolphin (Tursiops gephyreus) will have a future," said Dr. Lorenzo von Fersen, chairman of YAQU PACHA and curator for research and conservation at Nuremberg Zoo.

Veterinarians from around the world gathered in Valencia and then in the Canary Islands (Spain) for a training event on health assessment, rescue, and relocation of endangered river dolphins.
The workshop, organized by the National Marine Mammal Foundation (NMMF) in collaboration with Oceanogràfic Valencia and the University of Las Palmas, provided intensive training in health assessment techniques, including physical examination, biological sampling, and diagnostic ultrasound, in line with the One Health approach.
This special workshop focused not only on assessing the health status of river dolphins, but also on collecting data that is important for species conservation in rescue and relocation operations. Experts working with YAQU PACHA on river dolphin conservation in Colombia and Brazil also participated in the event, which provided an unprecedented opportunity for global collaboration, mutual learning, and capacity building.
This international collaboration is expected to foster new relationships and partnerships that are critical to the conservation of this endangered dolphin species.

Vaquita sanctuary to be expanded

vaquita

There is hope for the critically endangered vaquita, as this year's counts show an encouraging trend: for the first time, the population is no longer declining. More than a year ago, the Mexican government began placing concrete blocks with steel hooks in the vaquita's protected area in the Gulf of California. These measures have had a significant impact, with illegal fishing declining by 90%. Fishermen now avoid this area for fear of losing their nets. Due to the success of this measure, the protected area is now being expanded. The Mexican government plans to sink another 152 concrete blocks with steel hooks in the coming months.

Vaquita sanctuary Gulf of California Mexico

We warmly welcome this extremely promising development and are also actively working with Pesca ABC to develop and implement alternative fishing methods that will ensure that vaquitas no longer end up as bycatch in nets.

The bottlenose dolphin – adapting to climate change

Bottlenose dolphin Tursiops gephyreus Brazil climate change

Climatic changes have led to extensive restructuring of the world's oceans. Marine organisms have responded to new conditions with various biological systems, including genomic adaptations. The increasing accessibility of next-generation DNA sequencing methods for studying non-model species has recently made it possible to investigate genomic changes underlying environmental adaptations. This study used double-digested restriction site-associated DNA (ddRAD) sequencing data to investigate the genomic basis of ecotype formation in the currently recognized species and subspecies of bottlenose dolphins (genus Tursiops) in the southern hemisphere.

Tursiops truncatus gephyreus Brazil Atlantic Ocean climate change

Genomic divergence at the subspecies level has been confirmed between the coastal bottlenose dolphin (T. truncatus truncatus) and the coastal Lahille dolphin (T. t. gephyreus) in the southwestern Atlantic Ocean (SWAO). Similarly, divergence at the subspecies level is suspected between the coastal (eastern Australia) Indo-Pacific bottlenose dolphin (T. aduncus) and the proposed Burrunan dolphin (T. australis) from southern Australia. Coastal bottlenose dolphins generally had lower genomic diversity than offshore lineages, a pattern that was particularly evident in T. t. gephyreus, which showed exceptionally low diversity. Genomic regions associated with cardiovascular, musculoskeletal, and energy production systems appear to have undergone repeated adaptive evolution in coastal lineages in the southern hemisphere. We hypothesize that comparable selective pressures in the coastal environment have driven similar adaptive responses in each lineage, supporting the parallel evolution of coastal bottlenose dolphins. As climate change alters marine ecosystems worldwide, it is crucial to gain an understanding of the adaptability of local species and populations.
Our study provides insights into important adaptive pathways that may be important for the long-term survival of whales and other organisms in a changing marine environment.

Development of methods to reduce bycatch

bycatch pet bottles fishing nets Brazil GEMARS

Bycatch is the greatest threat to many dolphin species and populations worldwide. The La Plata dolphin or Franciscana – Toninha is one species in particular where bycatch has reached unsustainable levels in some regions. To combat this problem, we are actively working alongside our partners to develop practical solutions.
One promising approach is to attach empty (air-filled) PET bottles to fishing nets. These bottles create a strong echo when dolphins use their echolocation and approach the net.

The preliminary results of this approach are encouraging, although further testing is needed to statistically confirm this positive trend. If proven successful, this simple and inexpensive solution to a serious problem could represent an important step toward reducing bycatch. Furthermore, this method could also be applied in other regions of the world where similar challenges exist in dealing with other dolphin species.

Our partner GEMARS in Brazil has recognized that the success of such projects is only possible through close cooperation with the fishing community. Raising awareness among the local population about the urgency and effectiveness of such measures is therefore a central part of their work.

Rescue operation for river dolphins in Lake Tefé in the Amazon

River dolphins Rescue Lago Tefé Brazil Inia geoffrensis Sotalia fluviatilis

A dramatic mass extinction of river dolphins is currently taking place in the central Brazilian Amazon region. Dr. Miriam Marmontel, an experienced researcher at the Instituto de Desenvolvimento Sustentável Mamirauá, points out the seriousness of the situation: "We counted 130 dead dolphins in the last week alone." About 80% of these are typical Amazon river dolphins (Inia geoffrensis), while the remaining 20% are Tucuxi dolphins (Sotalia fluviatilis). In total, this corresponds to about 10% of the known population in Lago Tefé. "Such a high percentage of losses among Amazon river dolphins is alarming. If these numbers escalate, we could be facing the possible extinction of the species in Lake Tefé," warns Dr. Marmontel. She is leading the investigation into the causes in Brazil and taking important steps to protect the surviving animals, many of which are in dire need.
But this cannot be done alone, only in collaboration with others.

In this urgent matter, YAQU PACHA is working with our partners Dr. Marmontel and her team to save the remaining river dolphins and conduct a comprehensive scientific investigation into the causes of this tragic mass mortality. The alarmingly high mortality rate is currently attributed to rising water temperatures, which have reached alarming levels of 40 degrees Celsius in some areas.

River dolphins Lago Tefé Threat Rescue Inia geoffrensis Sotalia fluviatilis dead river dolphins Amazon

YAQU PACHA, in collaboration with the National Marine Mammal Foundation (NMMF) and Nuremberg Zoo, has developed an emergency plan to support Dr. Marmontel and her team in their efforts to save the remaining river dolphins and conduct a comprehensive scientific investigation into the causes of these tragic deaths. It is important to emphasize that this emergency plan is a joint effort supported by a variety of institutions, including YAQU PACHA, the National Marine Mammal Foundation (NMMF), Nuremberg Zoo, ZOOMARINE Portugal, L'Oceanografic Valencia, Planète Sauvage, LORO PARQUE Fundación, the Verein der Tiergartenfreunde Nürnberg e.V., the European Association for Aquatic Mammals (EAAM), Fundación MUNDO MARINO Argentina, and Rancho Texas.
All of these organizations have joined forces to support this vital rescue effort by collectively providing significant financial resources and sending qualified veterinarians from the US and European zoos. Our joint efforts also include coordinating veterinary care on site.

The survival of the remaining river dolphins (Inia geoffrensis and Sotalia fluviatilis) is under serious threat, and they urgently need our help to preserve the population in Lake Tefé.

Expedition to the Inias in the Río Casiquiare

Inias Río Casiquiare Venezuela dolphins inia geoffrensis expedition

Our partners from PROYECTO SOTALIA, led by Yurasi Briceño, and Fundación OMACHA, led by our colleague Fernando Trujillo, are currently traveling along the Río Casiquiare in Venezuela to survey the Inia population (Inia geoffrensis) and determine its numbers using river transects. This is the first time that an expedition to study Inias has been conducted on this river. Until now, nothing is known about the population size and distribution of Inias in this river system. The data is important for determining the threat status of Inias in Venezuela and developing appropriate measures to protect this dolphin species.

The Río Casiquiare connects South America's two major river basins, the Orinoco and the Amazon. This first expedition is a joint effort with Colombian colleagues in collaboration with government and academic institutions. Data on the size of the population, as well as the movement patterns and health status of Inia geoffrensis, will be collected. The Río Casiquiare is one of the most pristine, species-rich, and least explored places in the Venezuelan Amazon, and any contribution to knowledge about this area is valuable.

Feeding habits of sea lions

Our biologist Prof. Eduardo Secchi, together with other scientists, has published an article on the feeding habits of the South American fur seal (Arctocephalus australis) and the sub-Antarctic fur seal (Arctocephalus tropicalis). The study shows how the feeding habits of these two species have changed over the years and how the animals have partially switched their diet from fish to squid. This is probably due to the progressive overfishing of their prey by industrial fisheries. In addition, an increased intake of marine debris, especially flexible plastic material, by the animals was observed. The previous long-term study on which this article is based was supported by YAQU PACHA. For YAQU PACHA, scientific findings are the most important basis for the development of sustainable species conservation measures.

Vaquita's hopeful fight for survival

For decades, news about the vaquita (Phocoena sinus) has become increasingly depressing as the number of animals has declined year after year. Now there is new hope, as the latest estimate of the vaquita population in the upper Gulf of California in Mexico has revealed that the current population of the species is between 10 and 13 individuals, including one or two calves. This means that, compared to previous surveys, no further animals have been lost, and the population may even have grown by a few individuals. It is important to note that these figures are estimates.

Vaquita

The survey was conducted by the Cetacean Specialist Group of the International Union for Conservation of Nature (IUCN) in May 2023 in the Gulf of California (https://iucn-csg.org/wp-content/uploads/2023/06/Vaquita-Survey-2023-Main-Report.pdf).

The vaquita population has fallen to a critical level, mainly due to illegal fishing for shrimp and totoaba, another highly endangered species. It is important to note that between 1997 and 2008, the vaquita population declined from 567 to 245 individuals. Later, from 2008 to 2015, the decline rate of the porpoise increased from 8% to 45% per year. The latest estimate in 2021 assumed that there would only be seven or eight adult animals and one or two calves left.

To save the vaquita from extinction, fishing has been banned in a so-called zero-tolerance zone in the northern part of the Gulf of California, but illegal fishing still continues there. In August 2022, the Mexican Navy deployed 193 concrete blocks with three-meter-high metal hooks in the area to catch nets. In addition, the Mexican Navy has collaborated with the Sea Shepherd Conservation Society and other organizations to closely monitor fishing, which has led to a 90 percent reduction in fishing in the zero-tolerance zone, according to the study.

"The concrete blocks, together with enforcement within the ZTA, appear to be an effective means of preventing gillnets," according to the IUCN report. "Based on this year's results, expanding the concept of concrete blocks and hooks to other areas where vaquitas are known to forage is an urgent priority."

It is equally important to find solutions for fishermen who need to find a way to earn a living. The non-governmental organization Pesca Alternativa de Baja California (Pesca ABC) is dedicated to finding such solutions by developing alternative fishing techniques that do not use gillnets and helping fishermen create markets for their vaquita-friendly fish products.

For seven years, YAQU PACHA and Nuremberg Zoo have been supporting various NGOs such as Vaquita CPR, Pesca ABC, and Museo de la Ballena, which are working tirelessly to protect the vaquita. This is a first ray of hope for all of us, the first in decades, and it is ultimately thanks to the perseverance of the many people who are committed to protecting the vaquita. It would be wrong to say that the vaquita is saved; we are still a long way from that. Rather, it is important to take this news as an opportunity to continue working to protect the species.

Participation in politics

human ecology of the ocean spirit holy legislative politics

Our partners at ECOLOGIA HUMANA DO OCEANO at the Federal University of Espírito Santo in Brazil have been working on Brazilian government programs for several weeks. At a legislative assembly of the state of Espírito Santo, they presented our joint research with fishing communities and dolphins, such as the La Plata dolphin – Franciscana – Toninha. Knowledge and cooperation with traditional fishermen is important in reducing dolphin bycatch. The presentations also included the results of research on the impact of marine debris on dolphins. We are delighted that our joint work is now also being recognized by the Brazilian government and is influencing legislation to protect endangered dolphin species.

Dolphin Bycatch Meeting in Nuremberg

Bycatch in fishing nets is by far the greatest threat to many dolphin species. Although various methods have been developed and implemented to reduce bycatch, there is still much debate about the effectiveness of these measures, especially in the long term.

Bycatch Meeting Dolphins Nuremberg Zoo

Against this backdrop, a small meeting with scientists from Germany, France, Brazil, and Argentina took place at Nuremberg Zoo on the weekend of May 6 and 7, 2023. This meeting was held at the invitation of YAQU PACHA, which also covered the costs. The aim of this meeting was to analyze the methods currently in use and to examine how and to what extent these methods can be applied to the bycatch problem in two regions. On the one hand, in France, where the focus is on industrial fishing, but where other coastal fisheries using gillnets also cause high bycatch rates of small whales.

Bycatch Dolphins Conference Nuremberg Zoo

The second project discussed at the meeting concerns the dolphin species most affected by bycatch in the South Atlantic: the Franciscana. A pilot project is currently underway, led by Dr. Federico Sucunza, to test methods for reducing bycatch.

Bycatch Franciscana Dolphin Federico Sucunza

All participants agreed that both projects deserve the attention of experts and promised to work together to find solutions. In the case of Franciscana in particular, based on the discussions over the weekend, work is now underway on a four-year project to test four different methods of reducing bycatch in a bycatch hotspot.
Initial applications to obtain the necessary funding have already been prepared. Another larger follow-up meeting is planned.

Fishermen in Brazil and the Toninha

Local ecological knowledge of fishermen from southeastern and southern Brazil about the Toninha – Franciscana dolphin (Pontoporia blainvillei)

The Ecologia Humana do Oceano research group, based at the Federal University of Espirito Santo in southeastern Brazil, conducted a study with traditional fishermen in the Southwest Atlantic on the Toninha-Franciscana dolphin (Pontoporia blainvillei). The research team conducted interviews in ten fishing communities in southeastern and southern Brazil.

Interview with fisherman Toninha Franciscana, Brazil

Most fishermen who fish in the Franciscana dolphin's range were unable to identify this species. The fishermen who recognized the toninha explain that this dolphin is accidentally caught as bycatch in gillnets. As a rule, the carcasses are thrown overboard, but the fat and muscles can be used as bait for shark fishing and for human consumption. These fishermen do not know of any solutions to reduce the unintentional capture of Franciscana dolphins.

Interview with fisherman Toninha Franciscana, Brazil

The extent to which fishermen can identify toninha and provide data about them depends on their direct encounters with the animals. Consequently, local knowledge is influenced by the species' presence in fishing grounds, the type of fishing gear used, and the characteristics of the habitat (protected areas as opposed to the open sea). These conditions facilitate or hinder observation and contact with the Toninha, whose physical and behavioral characteristics already sufficiently limit its observation in the environment.

Interview with fisherman Toninha Franciscana Brazil Pontoporia blainvillei

The fishermen's knowledge of the Toninha was compared between the regions studied, and the researchers found that fishermen in the south of the country are more familiar with the species than those in southeastern Brazil. The results of this study suggest that awareness-raising measures for this species are needed in the fishing communities studied, particularly in the southeast of the country, where the Toninha is less well known.

When conditions were favorable for species recognition, fishermen were able to identify their characteristics and provide information about interactions with fisheries. Local ecological knowledge thus proves to be a useful tool for collecting data on Franciscana dolphin populations that overlap with fishing areas in the western South Atlantic.

Interview with fisherman Toninha Franciscana Brazil Pontoporia blainvillei

Local ecological knowledge (LEK) has been proven to be invaluable for wildlife conservation, as it contributes to a holistic understanding of ecosystems, improves conservation planning and management, and promotes cultural preservation and the strengthening of local communities. Integrating LEK with other scientific knowledge creates a more inclusive and effective approach to species conservation, ensuring the long-term well-being of both wildlife and local communities. With this in mind, YAQU PACHA is strengthening its commitment and involvement in LEK projects.

Final report on the flight count in Uruguay

The Franciscana aerial survey in Uruguay – a challenge
The Franciscana (Pontoporia blainvillei) is a small dolphin native to the coastal waters of Brazil, Uruguay, and Argentina. Franciscanas live mainly in coastal waters beyond the surf zone to a depth of 50 m, although they are also found in some bays and estuaries. The species is considered the most endangered dolphin species in South America, due to incidental killing in artisanal and industrial fisheries and increasing habitat destruction. The Franciscana is currently classified as "endangered" on the IUCN Red List of Threatened Species, and the National System of Protected Natural Areas (SNAP) in Uruguay considers it a priority species for conservation. Four Franciscana Management Areas (FMAs) have been proposed, of which FMA III in Rio Grande do Sul (southern Brazil) and along the Uruguayan coast has the highest bycatch estimates. In the past, Franciscana were killed in relatively large numbers in Uruguay (almost 4,000 animals between 1974 and 1993) and more recently in both Uruguay and Brazil (annual mortality of about 1,000–2,000 animals). Estimating the population size in this region is therefore important in order to assess the possible impact of this high fishing-related mortality on the population. So far, the population has only been estimated in the Brazilian part of FMA III, and no reliable estimates are available for Uruguayan waters.

Flight count Franciscana La Plata Dolphin Toninha Uruguay
From March 1 to April 4, 2023, with the support of YAQU PACHA, aerial surveys were conducted in Uruguayan waters to estimate the population of Franciscana dolphins and obtain records of the species' occurrence. The search for Franciscana groups was conducted from a twin-engine Aerocommander 500B high-wing aircraft at an almost constant altitude of 150 m (500 ft) and at a speed of 170-200 km/h (~90-110 knots).

Franciscana La Plata dolphin count Uruguay 2023

Three survey regions were proposed: i) Uruguayan offshore waters (30-50 m) (UY offshore stratum), ii) Uruguayan coastal waters (0-30 m) (UY inshore stratum), and iii) the Río de la Plata estuary in Uruguay (UY Río de la Plata stratum). A total of 2629 km of transects were surveyed over a total area of 49,483 km2, and a total of 53 Franciscana groups with an average group size of 1.8 individuals were recorded. The total density was estimated at 0.606 individuals/km², and the abundance for the entire area at 30,011 individuals (95% CI = 15,304–58,852). On the other hand, aerial surveys on the south coast of Brazil (a sector that is part of FMA III) covered a total area of 30,859 km2, and the total density was estimated at 0.426 individuals/km2 and the abundance at 13,137 individuals (95% CI = 7,037 – 24,526). Although the high abundance estimated for FMA III in this study could indicate a healthy status of this stock, the bycatch estimates for FMA III were the highest among all FMAs. This is the first study in which a complete aerial survey was conducted in FMA III and an estimate of abundance (43,148 individuals with 95% CI = 23,786 – 78,271) and density (0.537 individuals/km2) for the entire population, as well as previously unknown density and abundance values for Uruguayan waters. Continued monitoring of the population through aerial surveys is critical to better understand the impact of bycatch and other sources of unrecorded mortality on the population dynamics of Franciscana dolphins living in Uruguayan waters.

Volunteering in Brazil

Discovering the projects supported in Brazil.
For almost five years, I have been working as an animal keeper with the dolphins at Planète Sauvage, a zoo that has been supporting YAQU PACHA for many years. My job is to look after the animals' welfare on a daily basis, but also to participate in research and science and to raise awareness among as many people as possible about the protection of these species in their habitat.
I communicate with visitors every day and explain to them the importance of in-situ and ex-situ conservation work. As the problems caused by human activities in the sea are becoming ever greater, it is becoming more important every day to find new solutions to protect animal species, help wildlife, and preserve it.
But what about the projects we support on site every day?
I had been asking myself this question for some time. I wanted to see with my own eyes how the projects are implemented on site and where the money goes.
So I got the chance to travel to Rio Grande in southern Brazil for a month to see what YAQU PACHA's projects are all about. I took part in an internship to learn about YAQU PACHA's various species conservation projects and their daily work. The whole thing was in collaboration with the Federal University of Rio Grande FURG.
My stay began at CRAM FURG (Center for the Care of Marine Animals), where I was able to participate in the following activities.
Caring for the animals at the center (turtles, penguins, birds, sea lions), monitoring the beach, recording the different species of seabirds, pollution, strandings, and anthropogenic waste, releases, necropsies, hematological/parasitological analyses, and learning more about specific veterinary treatments such as ozone therapy and laser therapy.

cram furg Brazil Internship

In a second phase, I was placed in the ECOMEGA FURG laboratory for ecology and conservation of marine fauna. There I was able to learn about various studies and conservation projects, such as the Toninhas Project for the Franciscana dolphin and the Boto Project for Lahille's bottlenose dolphin.
I was allowed to accompany the Boto Project team on their regular trips out to sea to monitor the population using photo identification and DNA sampling.

Photo ID Bottlenose dolphin Brazil Volunteer work
Beach surveys are also conducted twice a month, during which stranded animals are counted and various samples (teeth, organs, skin, skulls) are taken from dead animals, which are then analyzed and examined in the laboratory.
For example, I learned that a single dolphin tooth can be used to examine a whole range of biological parameters.

ecomega furg Brazil Internship
After several steps, we produce thin tooth discs that we can use to determine the age of the animal. By removing material (dentin), we can also examine the isotopes present, which provide us with information about the animal's diet, possible migrations, and even the characteristics of its habitat throughout its entire life.
It is therefore one of the daily tasks of ECOMEGAto study these species, investigate their life expectancy, distribution, habitat use, population size, and even their habits and diet. By getting to know them better, we can reinforce the importance of measures to combat the problems caused by human activities in the sea and improve existing protection measures (protected areas where fishing is prohibited, pingers in fishing nets).
I returned from this internship with all the answers to my questions and all the keys I needed to share and pass on the new knowledge I had acquired on site to my colleagues and visitors to the park. It was a very enriching experience, both personally and professionally.
I would like to thank everyone I had the pleasure of meeting during my stay and thank you for your work. Thank you to the team from YAQU PACHA for the trust you have placed in me.

Long-term study on humpback whales published

Humpback whales migrate to tropical waters with temperatures ranging from 22 to 28 degrees Celsius to mate and give birth, where ocean warming could now lead to a shift in their range. Using data from regional surveys and 20 years of observations in a tropical and subtropical breeding area off the coast of Ecuador, we show that while whales prefer the tropical breeding area off Esmeraldas, whale sightings in the cooler subtropical breeding area increase under warmer (ENSO – El Niño) conditions. Our results suggest that under ENSO conditions, humpback whales may reach the limits of their temperature tolerance in the warm tropical waters around Esmeraldas, while under La Niña conditions, cooler areas such as Peru and Manabí are less suitable and the whales migrate further north.

Help us with your donation | In the context of species conservation, aerial surveys are a proven method for estimating population sizes. This is particularly true for dolphin species. Basically, this involves the use of aircraft flying at low altitude, from which human observers can see and count the animals they spot in the sea.

Aerial Survey Toninhas Aircraft Plane

YAQU PACHA has previously supported aerial surveys (aerial survey Toninhas in Brazil and Argentina) in estimating the population of the endangered La Plata dolphins – Franciscana – Toninhas. So far, there is only a gap in the population estimate in Uruguay. From March to April 2023, a group of biologists from Brazil and Uruguay will fly along the Uruguayan coast to count La Plata dolphins. This will be the first time that data on the population of this species in Uruguay has been collected.

Aerial Survey Toninhas Team YAQU PACHA Uruguay La Plata Dolphin Franciscana Donation

Aerial surveys are very expensive. They are carried out by companies that rent out aircraft.
One hour of aerial survey flying costs 1,000 euros. A total of 43 flying hours are planned, which means that the entire project will cost 43,000 euros.
Thanks to various non-governmental organizations and other sponsors such as Nuremberg Zoo and Verein der Tiergartenfreunde Nürnberg e.V., 35,000 euros have already been raised, meaning we still need to raise 8,000 euros.

Summary of a successful workshop

Yesterday was our last workshop day. For five days, more than 30 experts from 15 countries discussed how the human dimension can be applied to the conservation of dolphins and small whales. Our main goal at this workshop was to expand the concept of integrated species conservation by involving people, especially those who share their environment with endangered species. To achieve this goal, we invited not only field biologists but also experts such as psychologists, sociologists, anthropologists, tourism experts, and economics and communications specialists. Together, we shared our experiences in species conservation, held lively discussions, and developed ideas for the future.

The next step is to produce a report that can assist decision-makers in situations where the coexistence of animals and humans could be threatened, primarily by human activities.

We would like to express our gratitude to Nuremberg Zoo, theVerein der Tiergartenfreunde Nürnberg e.V.(Friends of Nuremberg Zoo Association), Aquazoo Düsseldorf, Heidelberg Zoo, Duisburg Zoo, Planete Sauvage, and Rancho Texas Lanzarote for their support.

News from our workshop

Yesterday evening, Dr. Lorenzo von Fersen, first chairman of our species conservation organization, opened the international workshop "Human Dimension in Small Cetacean Conservation" (strategies for winning people over to the protection of animal species). Thirty-four experts from various disciplines are meeting in Heilsbronn until December 21 to exchange experiences and develop new strategies.
Many of our biologists from South America are participating in this important workshop, and there is a lively exchange of experiences and many interesting lectures on this topic.
The workshop was organized and financed by YAQU PACHA, because it is extremely important to interest people in species conservation and motivate them to make their own contribution.
Even if it is only through financial support.
All of our species conservation projects are financed by donations and membership fees, and since we all work on a voluntary basis, 100% of the funds go to our projects in Latin America.
We will, of course, continue to report on the workshop and present the results afterwards.

Hormone analysis in marine mammals

Dr. Silvina Botta from ECOMEGA FURG, our partners in Brazil, is currently visiting the Endocrinology Laboratory at Toronto Zoo for a YAQU PACHA-sponsored training program on hormone analysis in marine mammals. Stress-related hormones such as cortisol are being analyzed in samples from bottlenose dolphins collected by ECOMEGA FURG and PROJETO BOTOS. The samples were obtained from tooth dentin using the automated MicroMill drilling system at ECOMEGA FURG. The main objective is to link stress hormone levels to environmental factors such as changes in prey availability or deteriorating habitat conditions.
