The President also announced that the government would pay fishermen for their loss of income. They reach sexual maturity when they are 3 to 6 years old.

Vaquitas feed on small fish, crustaceans (such as shrimp), and cephalopods (such as squid and octopuses). This amount is equal to a large percent of a year’s pay from legal fishing. We have focused our conservation efforts on totally eliminating fishing with gillnets within vaquita habitat.
They have been listed as endangered under the ESA since 1985. Mexican fisheries researchers have developed and tested some alternative fishing gear, with limited help from NOAA Fisheries and its partners. Fishermen can earn up to $8,500 for each kilogram of totoaba swim bladder. At this point in time, (2018, to be exact) the Vaquita Porpoise is critically endangered. Its numbers are decreasing with fewer than 19 remaining. This program which was joined by the Museo de la Ballena and the Government of Mexico continues into 2020 as illegal totoaba fishing. NOAA Fisheries is committed to the protection and recovery of the vaquita. You may also contact your closest NOAA Office of Law Enforcement field office during regular business hours. Fishing is thus a major source of income for the people there, who almost exclusively use gillnets, but vaquitas can also become accidentally wrapped in the nets and drown. In response Sea Shepherd Conservation Society initiated efforts to remove derelict and illegally set fishing gear from the Upper Gulf of California. In 2015, scientists placed 134 CPODs in a grid around the vaquita habitat. Because illegal fishing is still a problem, CIRVA recently recommended that the Mexican government and its partners increase enforcement efforts to stop illegal totoaba fishing. Since vaquitas were estimated to have only about 60 individuals in 2015, the acoustic data mean there were only about 30 individuals in 2016.
In early December, CIRVA conducted its 10th meeting at the Southwest Fisheries Science Center in La Jolla, California and released the CIRVA-10 report.
These are known as “gillnets.” It catches fish effectively by trapping their gills in a netting while the rest of their body is free. The tiny vaquita porpoise is the world’s smallest and most endangered cetacean species.
The Vaquita has become endangered for many reasons, but the gillnets which mistakenly capture them all too frequently are by far the leading reason for their decreasing size.
Because vaquitas are so close to extinction, CIRVA has met every 5 to 6 months since 2015 to discuss the status of the vaquita population and explore conservation efforts. It is a unique species, with a body shape and color pattern unlike that of … Change ), You are commenting using your Twitter account. NOAA Fisheries, the international recovery team (CIRVA) and the Mexican government recognize that saving vaquitas will require the following actions: NOAA Fisheries has provided technical expertise in a close collaboration with Mexican researchers for over 30 years. Vaquitas drown once entangled in these nets. Its extinction is imminent — and some even say, it's for the best.
( Log Out / Unfortunately, their actions did not stop the vaquita’s decline.
The vaquita (Phocoena sinus) is a critically endangered porpoise species native to the Gulf of California.
Scientists use a device called a CPOD, which can pick up the high-pitch vaquita clicks for months at a time, to gather over 3,000 days of data each year.
Change ), You are commenting using your Google account. This area also includes the Delta of the Colorado River Biosphere Reserve, one of the earth’s most diverse marine habitats. Catch nets were set on three days and two vaquitas were captured during field operations. Once scientists recognized the vaquita as a species, they also realized that small-scale and commercial fisheries were accidentally catching vaquitas.
Analysis of the 2011 to 2018 Acoustic Monitoring Program data combined with visual observations in 2017 and 2018 showed an estimated average annual rate of decline of 33%, corresponding to a population decline of 98.6% over this period.
