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.

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 to conduct a comprehensive scientific investigation into the causes of these tragic deaths. It is important to emphasize that this emergency plan is a collaborative 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, 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 together to support this vital rescue effort by jointly providing critical funding and sending qualified veterinarians from the U.S. and European zoos. Our joint efforts also include coordinating veterinary care in the field.

The survival of the remaining river dolphins(Inia geoffrensis and Sotalia fluviatilis) is acutely threatened and they urgently need our help to maintain the population in Lago Tefé.
