International effort announced to try to save the world's most endangered marine mammal
An ambitious, emergency plan to help save the vaquita porpoise from extinction in the northern Gulf of California has been recommended by the International Committee for the Recovery of the Vaquita (CIRVA). The plan involves relocating some of the remaining vaquitas to a temporary sanctuary, while crucial efforts aimed at eliminating illegal fishing and removing gillnets from their environment continue. The emergency action plan will be led by the Mexican government and supported by a consortium of marine mammal experts from more than a dozen organizations around the world.

VaquitaCPR (Conservation, Protection and Recovery) is an emergency action plan of the Mexican government with the input of an expert group of conservation scientists and marine mammal veterinarians. Recovery operations are set to begin in Mexico in the next few months. The plan acknowledges the many uncertainties involved in finding, catching and maintaining vaquitas in a temporary sanctuary. Vaquitas are not only rare, they avoid motorized vessels and no one can predict how they will react. "Unlike condors, we expect that most vaquitas will remain in the wild as capturing even a few will be very difficult," says Dr. Lorenzo Rojas-Bracho, lead vaquita researcher and head of CIRVA. "Having some is still better than having none. The decline is happening faster than solutions for illegal fishing, so we need to have multiple strategies."
While the vaquita is the animal most critically affected by the illegal fishing nets now, the lives of many other important species are also in jeopardy from the very same nets. Even if we are not able to save the vaquita, the situation must be controlled to protect turtles, sharks, dolphins and many other marine creatures. "Experts from around the world have come together and are working to save the vaquita in much the same way conservationists rescued the California condor from extinction in the 1980s," said Dr. Sam Ridgway, President of the National Marine Mammal Foundation. "We recognize that the odds are stacked against us, but the conservation and scientific communities feel a duty to act and we hope our collective expertise can make a difference."
The emergency action plan has been adopted by Secretaria de Medio Ambiente y Recursos Naturales (SEMARNAT) on the recommendation of their expert advisory group, the Comite Internacional Para La Recuperacion De La Vaquita (CIRVA). Under SEMARNAT leadership, the National Marine Mammal Foundation, The Marine Mammal Center, and the Chicago Zoological Society will help coordinate the efforts of a multi-institutional, international conservation team.
The precipitous decline of the vaquita has been primarily driven by accidental deaths of the porpoises in fishing gillnets. In 2015, the Mexican government instituted a two-year gillnet ban over the range of the vaquita. Additionally, the Mexican government implemented a financial compensation program to provide income to fishermen affected by the two-year gillnet ban. Despite strong enforcement, illegal gillnets are still being set to catch an endangered fish known as totoaba, the swim bladders of which fetch large sums of money on Hong Kong and Chinese black markets. Thus, despite tens of millions of dollars invested by the Mexican government in preventing vaquita by-catch, the population continues to decline.
VaquitaCPR is an international conservation program led by SEMARNAT in coordination with the National Marine Mammal Foundation, The Marine Mammal Center, and the Chicago Zoological Society. Key collaborators in Mexico include Instituto Nacional de Ecologia (INECC), Asociacion Mexicana de Habitats para la Interaccion y Proteccion de Mamiferos Marinos (AMHMAR), Baja Aqua Farms, and Acuario Oceanico. United States collaborators include Duke University and the U.S. Marine Mammal Commission, Disney Conservation Fund Rapid Response program, with the National Oceanic and Atmospheric Administration contributing technical support. European collaborators include Dolfinarium Harderwijk, Aarhus University, and Fjord&Baelt. Additional support and expertise has been offered from Dolphin Quest, SeaWorld, and the Vancouver Aquarium. Generous financial support from the Waitt Foundation and the Disney Conservation Rapid Response Fund helped with creation of the emergency action plan. VaquitaCPR operates as a private and public partnership, relying on both individual donors and government grants. For information about the plan, visit http://www.VaquitaCPR.org.
