Apr 16, 2015 · The tiny vaquita porpoise is the world’s smallest and most endangered cetacean species. The vaquita remains on the brink of extinction with approximately 10 remaining in 2023. Analysis of acoustic data from 2011 to 2018 combined with visual observations in 2017 and 2018 showed an estimated average annual rate of decline of 33%, corresponding ...

Given the continued decline of the vaquita population, CIRVA considered the question of ex situ approaches to vaquita conservation. While recognizing the risks and complexities of such an approach, CIRVA concluded that fieldwork to determine the feasibility of ex situ conservation actions for the vaquita is warranted.

• Expansion of the area of the Vaquita Refuge • Two year suspension of fishing activities that represent risk to vaquitas (esp. gillnets) • Compensation to licensees, fishermen and other workers in the shrimp, finfish and shark fisheries • Community-based surveillance and enforcement scheme

May 13, 2016 · CIRVA warns that accidental drowning in gillnets is rapidly driving the vaquita (Phocoena sinus) toward extinction. Previous research showed that the vaquita had declined from around 570 in 1997 to 250 in 2008. The vaquita is the most endangered marine mammal, indeed one of the most endangered mammals, in the world.

recovered, yielding 41 days of sampling data and a single day with vaquita detections. In 2016, surface buoys were used to mark each sampling site, resulting in greatly improved efficiency in checking CPODs and retrieving data. The spatial pattern of vaquita occurrence has been fairly consistent since monitoring began in 2011, although the

Department of State’s budget for energy and the environment to recover the vaquita, a small porpoise found only in the northern Gulf of California. The species numbers about 150 individuals and is teetering at the very brink of extinction. The major threat is …

vaquita is the marine mammal species most likely to go extinct.2 The primary threat is entanglement in gillnets set to catch shrimp and fish, primarily for U.S. markets. At the Commission’s May 2011 annual meeting, Mexican officials described their Action

Vaquita Session Summary . In April 2015, the President of Mexico formally announced a two-year closure of the vaquita range to gillnets with a commitment to full enforcement and a program to compensate the fisherman and other sectors of the fishing community of the upper Gulf of California.

leaders in their fields, and their determined work has been central to U.S. efforts to facilitate vaquita recovery. They have studied vaquita abundance and distribution, participated on the international recovery team, and provided numerous reports to inform the decision-makers who are responsible for vaquita recovery.
