Human Dimensions of Small Cetacean Conservation group group picture

We are pleased to share with you the results of the workshop on the human dimensions of small cetacean conservation that took place in Nuremberg in December 2022. Our main objective was to explore the impact of human behavior, thinking and perceptions on small cetacean conservation efforts. We discussed future challenges and opportunities and emphasized the importance of engaging local communities and stakeholders.

It is clear that a holistic approach that takes into account social, economic, cultural and political factors is crucial. Collaboration is key! We need to work hand in hand with conservation organizations, governments and local communities and adapt our strategies to changing needs and perspectives. Let's remember our key messages: Understanding human behavior is critical 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

right 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 highlight the need for sustainable tourism practices.

While whale watching is a popular ecotourism activity, it has been shown to have significant impacts on whale behavior and welfare if not managed properly. Through careful observation and data collection, this study investigated the impact of whale watching boats on various aspects of cetacean 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 mitigation 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 try to protect the whales, but also create new perspectives for the people who live in the area and have to coexist with the wildlife. In this way, we can preserve both biodiversity and the future of human populations.

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

Prof. Eduardo Secchi from the Universidade Federal do Rio Grande FURG - ECOMEGA made the start. We already have a 28-year partnership and 25 years of protecting the La Plata dolphin - Franciscana - Toninha(Pontoporia blainvillei). Prof. Secchi emphasized once again that the greatest dangers for the La Plata dolphin lie in bycatch and that we are continuing to work together to reduce the bycatch of this endangered dolphin species. The work at the university and contacts with government circles are now also opening up contacts with political decision-makers. Prof. Secchi announced that there will be talks in April 2024 about the establishment of a marine national park in Brazil, which would be crucial for the protection of the La Plata dolphin.

The next speaker was Dr. Aricia Duarte-Benvenuto from the University of São Paulo, Brazil. She is a veterinarian and part of the rehabilitation group for La Plata dolphins. For stranded La Plata dolphins, this group of specialists has been set up throughout the range of the La Plata dolphin to rescue stranded Franciscana dolphins - Toninhas - and rehabilitate them in specially equipped facilities. The work of this group is divided into 3 areas of expertise, rehabilitation, nutrition(special milk) and the examination of the dead animals (necropsy). Ms. Duarte-Benvenuto emphasized once again the significant progress that has already been made by these working groups and the importance of the exchange between veterinarians.

Dr. Federico Sucunza GEMARS then reported on our joint project to reduce bycatch of La Plata dolphins - Franciscana - Toninha and the Lahille dolphin. A simple and inexpensive method is used in which empty plastic bottles (filled with air) are mounted in the fishing nets. The air trapped in the bottles reflects the echolocation sounds of the dolphins and the dolphins recognize the fishing nets as an obstacle and avoid them. Dr. Sucunza reported an 85% reduction in bycatch among fishermen using this method. Discussions with fishermen and fishing communities are therefore an important part of our project in order to advise them and convince them of this method.

Fish guide from PESCA ABC for the protection of the vaquita

fishing guide pesca abc gulf of california vaquita

PESCA ABC, in collaboration with YAQU PACHA and other institutions, has taken an important step towards the protection of 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 testimony of our efforts to conserve marine resources in a responsible and ethical way.
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 its survival due to the use of gillnets, the PESCA ABC has committed to not using this method, which carries a high bycatch risk. Instead, selective fishing techniques have been chosen to 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 conservation of our natural resources.
In order to ensure compliance with the Protection of the vaquitaTo ensure the protection of turtles and non-target species, the catalog is supported by certifications that confirm the 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 fast and humane method guarantees the quality and freshness of the fish while respecting the welfare of the animals. By introducing this technique, we are reaffirming 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 and respect for all marine life. We invite everyone to join us on our journey towards a future where we can enjoy the richness of the ocean without compromising its integrity.
This fishing guide to the Protection of the vaquita was made possible by the support of Alumbra Innovations Foundation, Cetacean Action Treasury, Oceans 5, Marisla Foundation, Association of Zoos and Aquariums - Safe program, The Living Desert - Zoo and GardensYaqu Pacha e.V. realized.

Lahille dolphin workshop in Brazil

Lahille Dolphin Workshop Brazil Bottlenose dolphin Brasil

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

For two days, the participants engaged in intensive discussions, data analysis and joint planning sessions. The workshop began with comprehensive presentations on the current status of Lahille bottlenose dolphin populations, their endangered 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 collaborative conservation efforts. As the draft CMP continues to be refined and consulted in the coming months, the workshop is a testament to the power of international cooperation. As an NGO, YAQU PACHA strongly supports this CMP and is already involved in the implementation of several projects that we have defined in the five-year action plan .

Vaquita: perfectly BLOCKED!

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

Creative approach to species conservation
In 2023, a groundbreaking step was taken in the fight against illegal fishing. By introducing innovative concrete blocks with steel hooks in the habitat of the endangered vaquitas, fishing nets could be effectively trapped and the lethal impact on the species reduced. This step marks a turning point in the protection of the vaquitas, as illegal fishing numbers fell by around 90 percent for the first time. For the endangered vaquitas in the Gulf of California, there is hope for the future.
This innovative method not only protects the vaquitas, but also sets a global example: Creative approaches and collaborations can produce effective solutions to complex environmental problems.

Five-year conservation strategy for the Lahille's bottlenose dolphin

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

The conservation of biodiversity remains an urgent imperative for the health of our planet. With the increasing challenges posed by man-made problems, the conservation of each species is becoming a critical priority. The Lahille's bottlenose dolphin(Tursiops gephyreus), of which there are no more than 600 left, faces increasing threats from habitat destruction, pollution, bycatch and climate change, highlighting the urgent need for concerted conservation action.

In view of the endangered status of the Lahille's bottlenose dolphin, YAQU PACHA and Nuremberg Zoo, together with the Gephyreus Working Groupfrom Brazil, initiated a strategic action that was published just a few days ago. The aim of this collaboration was to define 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 consultation, review and expert input. Five strategic areas have been identified: (1) Scientific research and conservation, (2) Legislation and policy, (3) Communication, outreach and awareness, (4) Institutional strengthening and education, and (5) Citizen science.

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

This 5-year strategic plan underscores the commitment to addressing the multiple challenges facing Lahille's bottlenose dolphins. By fostering international cooperation, increasing stakeholder engagement and prioritizing targeted actions, stakeholders remain firmly committed to protecting this critically 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's Bottlenose dolphin(Tursiops gephyreus) will have a future," said Dr. Lorenzo von Fersen, Chairman of YAQU PACHA and Curator of Research and Conservation at Nuremberg Zoo.

Veterinarians from around the world met in Valencia and then in the Canary Islands (Spain) for a training event on the health assessment, rescue and translocation of endangered river dolphins.
The workshop, organized by the National Marine Mammal Foundation(NMMF) in collaboration with the Oceanogràfic Valencia and the Univ. de 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 particular workshop focused not only on assessing the health status of river dolphins, but also on collecting data that is important for species conservation during rescue and translocation operations. Experts working with YAQU PACHA in 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 conservation area to be expanded


There is hope for the endangered vaquita, as the latest counts for this year 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 clear impact, with illegal fishing falling 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 extended. The Mexican government is planning to sink a further 152 concrete blocks with steel hooks over the next few months.

Vaquita Protected Area Gulf of California Mexico

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


The bottlenose dolphin - adapting to climate change

Bottlenose dolphin Tursiops gephyreus brazil brazil brazil climate change

Climatic changes have led to extensive restructuring of the world's oceans. Marine organisms have responded to new conditions with different biological systems, including genomic adaptations. The increasing accessibility of next-generation DNA sequencing methods to study non-model species has recently made it possible to investigate genomic changes underlying environmental adaptations. This study used double-digest 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 brazil atlantic ocean climate change

Genomic divergence at the subspecies level was confirmed between the inshore common bottlenose dolphin (T. truncatus truncatus) and the inshore Lahille's bottlenose dolphin(T. t. gephyreus) in the southwestern Atlantic Ocean (SWAO). Similarly, a divergence is suspected at the subspecies level between the coastal (eastern Australia) Indo-Pacific bottlenose dolphin(T. aduncus) and the proposed Burrunan bottlenose 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 had 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 nearshore environment have elicited similar adaptive responses in each lineage, supporting the parallel evolution of coastal bottlenose dolphins. As climate change alters marine ecosystems worldwide, it is critical to gain an understanding of the adaptive capacity of local species and populations.
Our study provides insights into key adaptive pathways that may be important for the long-term survival of cetaceans and other organisms in a changing marine environment.

Development of methods to reduce bycatch

bycatch bycatch pet bottles fishing nets brazil GEMARS

Bycatch is the biggest threat to many dolphin species and populations worldwide. The La Plata dolphin or Franciscana - Toninha in particular is a species where bycatch is reaching unsustainable levels in some regions. To counteract this problem, we are actively involved alongside our partners and are working together on practical solutions.
A first promising approach is to attach empty PET bottles (filled with air) to fishing nets. These bottles produce a strong echo when the dolphins use their echolocation and approach the net.

The preliminary results of this approach are encouraging, although further testing is required to statistically confirm this positive trend. This simple and cost-effective solution to a serious problem could, if successful, represent an important step towards reducing bycatch. Furthermore, this method could also be applied in other regions of the world where there are similar challenges 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 of the urgency and effectiveness of such measures is therefore a central component of their work.

Close cooperation with local organizations in South America is crucial for the successful implementation of our projects.
We also held talks with fishermen who are involved in our joint activities to reduce dolphin bycatch. Here, objects in the fishing nets (empty plastic bottles) are currently being tested so that the nets are recognized and avoided by the dolphins. This is a cost-effective alternative to acoustic signals (pingers).

The team around Sandra Honigs, Sebastian Schnock, Jolana and Mike Meister, with a booth at the Aquazoo Düsseldorf and Dr. Lorenzo von Fersen with an information booth and lectures at the zoo Nuremberg. The focus at the Aquazoo Düsseldorf was on river dolphins and our current rescue action for the river dolphins in Lago Tefé in Brazil. Many interested visitors came to the Aquazoo and interesting conversations ensued. The visitors were horrified about the extent of the dolphin death in Brazil.
In 3 lectures Dr. Lorenzo von Fersen informed the visitors of Nuremberg Zoo about our species conservation projects in Latin America. The main focus was on our work to preserve the population of the Franciscana Dolphin - Toninha(Pontoporia blainvillei) in the coastal waters from Brazil to Argentina and our efforts to protect the endangered Vaquita in the Gulf of California. Another important item, of course, was our current rescue effort for river dolphins in Lago Tefé in Brazil. Teams from our partners are on site and are currently trying to move the dolphins to somewhat cooler regions of the lake. Extremely high water temperatures around 39 degrees Celsius are the main cause for the mass death of the river dolphins.
A big thank you to all visitors of the Species Protection Day and for your interest in our work.

At the Week of Knowledge at the Federal University of Espírito Santo in Brazil, our partners from Ecologia Humana do Oceano informed children and interested visitors about dolphins and our projects.
There was also an area where our research was presented in a scientific exhibition. This was about the ethnobiology of the dolphin Sotalia guianensis in the state of Espírito Santo, Brazil. The project presented is a partnership between Ecologia Humana do Oceano and fishing communities.
YAQU PACHA has been supporting projects like this for several years. Working with fishermen and fishing communities is important to reduce dolphin bycatch.

Rescue operation for river dolphins in Lago Tefé in the Amazon

River dolphins rescue Lago Tefé Brazil Inia geoffrensis Sotalia fluviatilis

A dramatic mass mortality of river dolphins is currently taking place in the central Brazilian Amazon. 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 them are the typical Amazon dolphins(Inia geoffrensis), and the remaining 20% are Tucuxi dolphins(Sotalia fluviatilis). In total, this represents about 10% of the known population in Lago Tefé. "Such a high percentage of losses in the Amazon dolphin is alarming. If these numbers escalate, we could be looking at a possible extinction of the species in Lago Tefé," warns Dr. Marmontel. She is leading the cause research in Brazil and taking important steps to protect the surviving animals, many of whom are in dire need.
But this cannot be done alone, but only in cooperation with others.

In this urgent matter, YAQU PACHA is working with our partners to support 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 an alarming 40 degrees Celsius in some areas.

Día Internacional del Delfín Franciscana

Día Internacional del Delfín Franciscana dia da toninha pontoporia blainvillei la plata dolphin

Dia da Toninha - Today is the International Day of the La Plata Dol phin - Franciscana - Toninha.
The Franciscana Dolphin(Pontoporia blainvillei) - Toninha (Brazil) and the Lahille's Bottlenose Dolphin(Tursiops gephyreus) are the most endangered dolphin species in South America.
Franciscana dolphins live in coastal waters from Brazil to Uruguay to Argentina, and YAQU PACHA has been working to protect this dolphin species from extinction since 1996.
Together with other partners, the Consorcio Franciscana was also created a few years ago to work more effectively with other partners to protect this endangered species.
Together with biologists and scientists from Brazil and Uruguay, we were also able, for example, to successfully carry out the first flight counts in 2023 to determine the population of the La Plata Dolphin - Delfín Franciscana(Pontoporia blainvillei) in Uruguay.
October 1 - Dia da Toninha - is the day to jointly raise awareness of the situation of these animals and YAQU PACHA will continue to work tirelessly for the protection and conservation of this endangered dolphin species.

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 on the Río Casiquiare in Venezuela to survey the Inia population(Inia geoffrensis) and determine their numbers from river transects. This is the first time that an expedition to study Inias has been conducted in this river. To date, nothing is known about the population size and distribution of Inias in this river system. The data are important to determine the threat status of inias in Venezuela and to develop appropriate measures to protect this dolphin species.

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

Species Conservation Day at Duisburg Zoo

Species Protection Day 2023 Duisburg Zoo Info Booth YAQU PACHA

With bright sunshine YAQU PACHA was allowed to be a guest at the Duisburg Zoo on Saturday for the Species Protection Day. It was a great day with many nice conversations about the protection of aquatic mammals and many Euros went into the donation box. But also the stuffed animal assortment arrived as usual, until at the end of the day it was said... manatee and puffin sold out! But also penguins and dolphins found new friends. We would like to thank Duisburg Zoo for the organization and support and the helping hands of Silke Klein, Jolana and Mike Meister as well as our regular guest Barbara Mila. Thank you to Sandra Honigs for organizing the info booth for Species Protection Day 2023.

Dietary habits of fur seals

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

Vaquita's hopeful fight for survival

For decades, news about the vaquita(Phocoena sinus) has become increasingly depressing as numbers 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 10 to 13 individuals, including one or two calves. This means that no additional animals have been lost compared to previous surveys, perhaps the population has increased by a few individuals. It is important to note that these numbers are estimates.


The survey was conducted by the Cetacean Specialist Group of the International Union for Conservation of Nature (IUCN) in the Gulf of California in May 2023 (

The vaquita population has declined to critical levels, mainly due to illegal fishing of shrimp and totoaba, another highly threatened species. It is important to point out that between 1997 and 2008, the vaquita population decreased from 567 to 245 individuals. Later, from 2008 to 2015, the rate of decline of the harbor porpoise increased from 8% to 45% per year. The last estimate in 2021 assumed that there would be only seven or eight adults and one or two calves.

To save the vaquita from extinction, fishing was banned in a so-called zero-tolerance area in the northern part of the Gulf of California, but illegal fishing still takes place there. In August 2022, the Mexican Navy deployed 193 concrete blocks in the area with three-meter-high metal hooks designed to snag nets. In addition, the Mexican Navy has worked with the Sea Shepherd Conservation Society and other organizations to closely monitor the fishery, resulting in a 90 percent reduction in fishing in the zero-tolerance zone, the study said.

"The concrete blocks, along with enforcement within the ZTA, appear to be an effective means of preventing gill netting," the IUCN report said. "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."

Dr. Lorenzo Rojas-Bracho Vaquita

It is equally important to find solutions for fishermen who need to find a way to make money. The non-governmental organization Pesca Alternativa de Baja California (Pesca ABC) is dedicated to finding such solutions by developing alternative fishing techniques without gillnets and helping fishermen create markets for their vaquita-friendly fish products.

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

Participation in politics

ecologia humana do oceano espirito santo legislativa politics

Our partners from ECOLOGIA HUMANA DO OCEANO from the Federal University of Espírito Santo in Brazil have been collaborating in government programs of the Brazilian Government 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. The knowledge and collaboration with traditional fishermen is important to reduce dolphin bycatch. During the presentations, the results on the impact of marine debris on dolphins were also presented and discussed. We are happy that our joint work is now also noticed by the Brazilian government and has influence on laws for the protection of endangered dolphin species.

YAQU PACHA Annual General Meeting

Our YAQU PACHA Annual General Meeting this year was held on Friday, May 26, 2023 from 6:30 to 8:30 pm at the Natural History House of the Nuremberg Zoo and also via Zoom Conference our biologists and society members attended the event.

Dr. Lorenzo von Fersen 1st Chairman YAQU PACHA e.V. Annual General Meeting

Dr. Lorenzo von Fersen (1st chairman YAQU PACHA e.V.) led through the event. After a short introduction, first our biologists from Latin America reported about the work on their projects.

Prof. Eduardo Secchi Ecomega FURG Brazil Annual General Meeting Training Toronto Zoo

Prof. Eduardo Secchi began by presenting the projects that are being carried out with our partners from ECOMEGA FURG from the Federal University of Rio Grande FURG in Brazil. Special attention is given to the cooperation with fishing communities and schools in order to reduce the bycatch of marine mammals in the long term and to intensify the contact with fishermen. The project also aims to integrate the topic of nature and species conservation into school lessons in the long term. Prof. Secchi's team is also working on setting up a hormone physiology laboratory for the analysis of cortisol and other hormones from samples of the species living there. Dr. Silvina Botta participated in a training course at the world-renowned Toronto Zoo laboratory of Dr. Mastromonaco.

Dr. Lorenzo Rochas-Bracho Vaquita Annual General Meeting

Dr. Lorenzo Rojas-Bracho then reported on the work to protect the endangered vaquita. He presented the work of PESCA ABC, which implements alternative fishing methods to prevent bycatch of vaquitas. Through the government of Mexico, heavy concrete blocks with metal hooks have also been sunk in the vaquitas' distribution area to prevent fishing in this area, as the nets would be destroyed by these metal hooks. Apparently this is already having a positive effect and fishermen seem to be avoiding these areas. In the last 3 weeks, Dr. Rojas-Bracho's team has again made expeditions to count vaquitas and there have been sightings of animals again, which makes us feel positive.

Dr. Federico Sucunza Gemars Instituto Aqualie Annual General Meeting La Plata Dolphin Franciscana Toninha

Then Dr. Federico Sucunza from our partners GEMARS and INSTITUTO AQUALIE presented his work in the protection of the La Plata Dolphin - Franciscana - Toninha and reported on the flight counts that were carried out for the first time in Uruguay in March and April. After evaluating the data, we can currently assume a population of about 30000 Franciscanas in Uruguay, where there is a very high mortality due to bycatch. To counteract this, we are working together to install acoustic signals, such as pingers. Dr. Federico Sucunza also reported on our collaboration with the PROJETO PESCA team to test and establish a simple and low-cost alternative to pingers. It turns out that empty plastic bottles mounted in the nets are perceived by the dolphins, so they avoid the nets. Initial tests were very successful.

Yurasi Briceño Venezuela Proyecto Sotalia Inia geoffrensis Manati YAQU PACHA

Afterwards, our biologist Yurasi Briceño from our partners PROYECTO SOTALIA reported on her work in protecting the river dolphins Inia geoffensis and Sotalia and the manatees in Venezuela. Oil exploration in Lake Maracaibo and the extraction of gold using mercury pose a serious threat to the animals, and it turns out that the mercury accumulates so much in the fish that it also becomes a serious threat to humans through the food cycle. The work of the team around Yurasi Briceño covers many areas, such as regular population counts of the animals and an important area is also environmental education.

Lahille's bottlenose dolphin Dr. Lorenzo von Fersen YAQU PACHA

Dr. von Fersen then reported on the measures being taken specifically to protect the endangered Lahille's bottlenose dolphin(Tursiops truncatus gephyreus) in Brazil.

Another focus of YAQU PACHA's work is the so-called capacity building, the development of competencies and the training and further education of our employees.

YAQU PACHA was also instrumental in establishing the Alliance for Franciscana Dolphin, which develops conservation plans for the endangered La Plata Dolphin - Franciscana - Toninha(Pontoporia blainvillei) in various working groups.

The Latin American Journal for Aquatic Mammals LAJAM looked back on its 20th anniversary and YAQU PACHA has been a major sponsor of this important scientific journal since its inception.

In 2022, YAQU PACHA was also the main sponsor of the 19th RT of SOLAMAC, the most important working meeting for biologists working on the conservation of aquatic mammal species in Latin America.

Dr. von Fersen also reported on the major international workshop Human Dimension in small Cetacean Conservation organized and conducted by YAQU PACHA. A final report will follow shortly.

Another important part of our work was the cooperation with the group ECOLOGIA HUMANA DO OCEANO, which is led by our biologist Camilah Antunes Zappes in Brazil and whose focus is the connection between humans and the environment. The group's main activities are environmental education in schools and kindergartens and communication with fishing communities.

Sandra Honigs (2nd chairwoman, YAQU PACHA e.V.) presented the work and activities of YAQU PACHA in Germany and Europe. At this point a big thank you to all volunteers, without whose help our events and activities would not be possible.

Finally, Dr. Lorenzo von Fersen presented the new YAQU PACHA for Diversity program, which uses the example of Lahille's bottlenose dolphin (current population 600 individuals) to show why it is so important to preserve and protect biodiversity.

The detailed minutes of the Annual General Meeting with all the activities of our organization will also be available here on our website shortly.

Dolphin bycatch meeting in Nuremberg

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

Bycatch meeting dolphins Nuremberg Zoo

Against this background, a small meeting with scientists from Germany, France, Brazil and Argentina took place in the Nuremberg Zoo on the weekend of May 6 and 7, 2023. This meeting took place at the invitation of YAQU PACHA, which also covered the costs. The objective of this meeting was to analyze the methods currently used and to consider how and to what extent these methods can be applied to the bycatch problem in two regions. First, in France, where the focus is on industrial fisheries, but where other coastal fisheries with gillnets also cause high bycatch rates of small cetaceans.

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. Under the leadership of Dr. Federico Sucunza, a pilot project is currently underway to test bycatch mitigation methods.

Bycatch Franciscana dolphin Federico Sucunza

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

Fishermen in Brazil and the Toninha

Local ecological knowledge of fishermen from the southeast and south of 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 fishers in the southwest Atlantic Ocean about the Toninha - Franciscana dolphin(Pontoporia blainvillei). The research team conducted interviews in ten fishing communities in southeastern and southern Brazil.

Interview fisherman Toninha Franciscana Brazil

Most fishermen fishing in the range of the Franciscana dolphin have not been able to identify this species. The fishermen who have identified the Toninha explain that this dolphin is accidentally caught as bycatch in gill nets. Usually the carcasses are thrown overboard, but the fat and muscle can be used as bait for shark fishing and human consumption. These fishermen are not aware of any solutions to reduce the incidental catch of Franciscana dolphins.

Interview fisherman Toninha Franciscana Brazil

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

Interview fisherman Toninha Franciscana Brazil Pontoporia blainvillei

Fishermen's knowledge of the Toninha was compared between the regions studied and the researchers found that fishermen in the south of the country were more aware of the species than fishermen in southeastern Brazil. The results of this study suggest that actions to raise awareness of the species are needed in the fishing communities studied, especially in the southeast of the country, where the toninha is less known.

When conditions were favorable for identifying the species, fishermen were able to determine its characteristics and provide information on 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 fisherman Toninha Franciscana Brazil Pontoporia blainvillei

Local Ecological Knowledge (LEK) has been shown to be invaluable for wildlife conservation, contributing to a holistic understanding of ecosystems, improving conservation planning and management, and promoting cultural preservation and empowerment of local communities. Integrating LEK with other scientific knowledge creates a more inclusive and effective approach to species conservation that ensures the long-term well-being of both wildlife and local communities. With this in mind, YAQU PACHA is increasing its involvement and participation in LEK projects.

Final report of the flight census in Uruguay

The Franciscana Flight Count 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 also occur in some bays and estuaries. The species is considered the most threatened 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 Uruguay's National System of Protected Natural Areas(SNAP) 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 the Uruguayan coast have the highest bycatch estimates. Historically, franciscana have been killed in relatively large numbers in Uruguay (nearly 4000 animals between 1974 and 1993) and more recently in both Uruguay and Brazil (annual mortality of about 1000-2000 animals). Estimating stock size in this region is therefore important to assess the potential impact of this high fishing-related mortality on the stock. To date, the stock size has only been estimated in the Brazilian portion of FMA III and no reliable estimates are available for Uruguayan waters.

Flight Count Franciscana La Plata Dolphin Toninha Uruguay
From 01 March to 04 April 2023, aerial surveys, supported by YAQU PACHA, were conducted in Uruguayan waters to estimate the population of Franciscana dolphins and obtain records of the species' abundance. The search for Franciscana groups was conducted from a twin-engine Aerocommander 500B high-wing aircraft at an approximately constant altitude of 150 m (500 ft) and at a speed of 170-200 km/h (~90-110 knots).

Flight Count Franciscana La Plata Dolphin Toninha 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) Río de la Plata estuary in Uruguay (UY-Río de la Plata stratum). A total of 2629 km of transects were surveyed covering a total area of 49,483 km2 and a total of 53 franciscana groups were recorded with an average group size of 1.8 individuals. The total density was estimated at 0.606 individuals/km2 and the abundance for the whole area was 30,011 individuals (95% CI = 15,304 - 58,852). On the other hand, aerial surveys of the southern coast of Brazil (sector that is part of FMA III) covered a total area of 30,859 km2, and total density was estimated at 0.426 individuals/km2 and abundance at 13,137 individuals (95% CI = 7,037 - 24,526). Although the high abundance estimated for FMA III in this study may indicate a healthy status for this stock, the bycatch estimates for FMA III were the highest among all FMAs. This is the first study to conduct a full aerial survey of FMA III and obtain an estimate of abundance (43,148 individuals with 95% CI = 23,786 - 78,271) and density (0.537 individuals/km2) for the entire stock, as well as previously unknown density and abundance values for Uruguayan waters. Continued population monitoring through aerial surveys is critical to better understand the effects of bycatch and other sources of unrecorded mortality on the population dynamics of Franciscana dolphins living in Uruguayan waters.

Volunteering in Brazil

On a journey of discovery to the supported projects in Brazil.
For almost five years I have been working as an animal keeper with the dolphins of Planète Sauvage, a zoo that has supported YAQU PACHA for many years. My work consists in taking care of the animals' welfare on a daily basis, but also in participating in research and science and in raising awareness among as many people as possible about the protection of these species in their habitat,
I communicate daily with visitors 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 increasing, it is becoming more and more important every day to find new solutions to protect species, help wildlife and conserve them.
But what about the projects we support on the ground every day?
This was a question I had been asking myself for some time. I wanted to see with my own eyes how the projects are implemented on the ground and where the money goes.
So I got the chance to travel to the south of Brazil, to Rio Grande, for a month to see what YAQU PACHA's projects are all about. I participated in an internship to get to know the different species conservation projects of YAQU PACHA and the daily work. The whole thing 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.
Care of the animals in the center (turtles, penguins, birds, sea lions), monitoring on the beach, recording of the different species of sea birds, pollution, strandings and anthropogenic waste, releases, necropsies, hematological / parasitological analysis or more about certain veterinary treatments such as ozone therapy or laser therapy.

cram furg Brazil traineeship

In a second phase, I was placed in the Laboratory of Ecology and Conservation of Marine Fauna ECOMEGA FURG. There I was able to get to know the different studies and conservation projects, such as the Toninhas Project for the Fransiscana dolphin or the Boto Project for the Lahille's porpoise.
I was allowed to accompany the Boto Project team on their regular trips to the sea to monitor the population with photo-identification and DNA samples.

Photo ID bottlenose dolphin Brazil Volunteer
Beach observations are also conducted twice a month, during which stranded animals are counted and various samples (teeth, organs, skin, skull) are taken from dead animals for analysis and examination in the laboratory.
For example, I learned that a single dolphin tooth can be used to study a whole range of biological parameters.

ecomega furg Brazil Volunteer
After several working steps, we make thin tooth slices, which allow us to determine the age of the animal. By taking material (dentin) we can also examine the isotopes present, which give us information about the diet, possible migrations or even the characteristics of the animal's habitat throughout its life.
It is therefore one of the daily tasks of ECOMEGA, to study these species, their life expectancy, their distribution, the use of their habitat, the size of their populations or even their habits and diet. If we know them better, we will be able to underpin the importance of measures to combat the problems caused by human activities in the sea and improve the protection measures already in place (protected areas where fishing is prohibited, pingers in fishing nets).
I have returned from this volunteering with all the answers to my questions, with all the keys in my hand to share and pass on the new knowledge I have acquired in the field with my colleagues and the visitors to the park. It was a very enriching experience, both personally and professionally.
Thank you to everyone I had the pleasure of meeting during this stay and thank you for your work. Thanks to the Team from YAQU PACHA for the trust placed in me.

Long-term study on humpback whales published

Humpback whales migrate to tropical waters with temperatures of 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 are increasing under warmer (ENSO - El Niño) conditions. Our results suggest that under ENSO conditions, humpback whales can reach the limit 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 move further north.

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

Aerial Survey Toninhas 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, only Uruguay has a gap in the population estimate. From March to April 2023, a group of biologists from Brazil and Uruguay will fly along the Uruguayan coast to count La Plata dolphins. It will be the first time that data will be collected on the population of this species in Uruguay.

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 airplanes.
One flight hour aerial survey Toninhas costs 1000 EURO. A total of 43 flight hours are planned, which means that the whole project will cost 43000 EURO.
Thanks to various non-governmental organizations and other sponsors such as Tiergarten Nürnberg and Verein der Tiergartenfreunde Nürnberg e.V., 35000 EURO have already been collected, which means we still need to collect 8000 EURO.
The La Plata dolphin is the most endangered dolphin species in South America and urgently needs our help!
YAQU PACHA coordinates the protection efforts in Europe to save this dolphin species.

Species protection

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 cetaceans. Our main goal at this workshop was to broaden the concept of integrated 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 business and communication 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 be used by decision-makers in situations where the coexistence of animals and humans may be threatened, particularly by human activities.

We would particularly like to thank Nuremberg Zoo, theNuremberg Zoo Friends 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 to win people for the protection of animal species). 34 experts from various disciplines are meeting in Heilsbronn until 21 December to exchange experiences and develop new strategies.
Many of our biologists from South America are taking part in this important workshop and there is a lively exchange of experiences and many interesting presentations on this topic.
The workshop was organized and financed by YAQU PACHA, because it is extremely important to get people interested in species conservation and to motivate them to make a contribution themselves.
Be it only through financial support.
All our species conservation projects are financed by donations and membership fees and as we all work on a voluntary basis, 100% of the money goes to our projects in Latin America.
We will of course continue to report on the workshop and then present the results.

Specialist training, Pantanal 2022

Report by Maria Jimena Valderrama, veterinarian, from our partner organization Fundación Omacha

Thanks to Yaqu Pacha, I was able to travel from Bogota to Pantanal, Brazil, to participate in the 10th International Training Course for Wildlife Work, organized by the Tamandua Institute, for which I received a scholarship from FINN (Foundation for International Aid Animals).
During this course, I deepened my knowledge and skills for wildlife management in the wild. From capturing and sampling, clinical assessment and field monitoring of different wildlife species to in-depth discussions on animal health.
In addition, this meeting of different professionals working in conservation in Latin America was a place to discuss ideas, share knowledge and experiences to develop and strengthen strategies that address all the problems that arise in conservation medicine today.

Hormone analysis in marine mammals

Dr. Silvina Botta from ECOMEGA FURG, our partners in Brazil, is currently visiting the endocrinology lab at the Toronto Zoo for a training program on hormone analysis in marine mammals sponsored by YAQU PACHA. Stress-associated hormones such as cortisol are being analyzed in samples of Lahille's porpoises from 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 deteriorated habitat conditions.

20 years of Yaqu Pacha Chile

Congratulations also from our side and we would like to take this opportunity to thank you for the great cooperation with our local biologists over the years.
Yaqu Pacha Chile is currently working on a project NAVEGA con el delfín chileno and an article about it was published in a magazine in Chile.

Congress for Aquatic Mammals in Palm Beach

One of YAQU PACHA's main objectives is to provide educational opportunities for Latin American students and professionals. We are convinced that this will prepare these people to be the leading scientists in their home countries and that this is the best foundation for a successful and sustainable scientific culture.
In recent years, YAQU PACHA has offered targeted support programs to enable students, biologists and veterinarians not only to learn new research methods, but also to build a network that will help them navigate the world of science.

This is Raphaela Mota and her participation in the most important congress for aquatic mammals in August 2022 in Palm Beach, Florida, USA.
She then spent a month with Randy Wells to learn research methods. Her participation and training were paid for by YAQU PACHA.

Specialist training, Sarasota, May 2022

Report by Maria Jimena Valderrama, veterinarian, from our partner organization Fundación Omacha

During the annual bottlenose dolphin health survey in Sarasota, Florida, organized by the Chicago Zoological Society and the Dolphin Biology Research Institute, I participated as an invited researcher, working in or near the waters of Sarasota Bay and surrounding areas with free-ranging dolphins.
This opportunity allowed me to deepen my knowledge of dolphin population health assessment through specialized clinical examinations, ultrasound, sample collection and processing, analysis of physiological processes, and additional methods for identifying and capturing small cetacean populations. I would like to apply all of this in my work in South America with the endangered river dolphins.
The Omacha Foundation has been working to protect them and aquatic ecosystems for around 30 years, but there is an urgent need to use new conservation medicine techniques to meet the new challenges posed by emerging diseases and new threats that may affect this species and its ecosystems.
This space was also a place to share experiences and knowledge with different institutions such as the National Foundation for Marine Mammals, where new alliances were created for joint work in Colombia.
