The small porpoises, which range from 4 to 5 feet in length, often become entangled and die in the large mesh gillnets used by poachers hunting the totoaba, an endangered fish highly valued in some countries for its perceived medicinal properties. This little porpoise was only discovered in 1958, yet it's already on the brink of extinction. We tend to not pay attention until we are in total crisis mode, she says, noting that conservation efforts didnt really start until there were just a few hundred vaquitas left. Take action and ask Mexican President Pea Nieto to enforce protection of the vaquita. There, they suffer from bycatch, often getting caught in fishing nets meant for other species. Vaquitas, alongside sea turtles and whales, can easily become entangled in the massive mesh netting known as gillnets used by totoaba poachers and local fishers. "The vaquita is symbolic of the unique diversity found in the Gulf of California, which was described by John Steinbeck in his wonderful 1951 book 'The Log From the Sea of Cortez,'" said Wayne, a distinguished professor of ecology and evolutionary biology and a Howard Hughes Medical institute professor.

The vaquitas, about 4 to 5 feet (1.2 to 1.5 meters) in length, end up as x26quot;bycatchx26quot; since they aren't the intended target of the nets. The International Union for Conservation of Nature estimates that there are between 50 and 1,000 axolotls left in the wild. With Sea Shepherd gone, observers have claimed that illegal gillnets are being blatantly placed in the water, with buoys clearly labelling them. Get focused newsletters especially designed to be concise and easy to digest. "Genetic diversity in vaquitas is not so low that it constitutes a threat to their health and persistence. "In a very short period of time, a series of accidental events in a certain place and time could generate the definitive disappearance of the species; the risk is imminent of continuing illegal fishing as it has been until now," said Luis Medrano Gonzlez, researcher and professor at the Faculty of Sciences of the Autonomous University of Mexico. This is what happened. Newborn vaquita have darker coloration and a wide gray fringe of color that runs from the head to the flukes, passing through the dorsal and pectoral fins. 2023-05-01T10:41:43.832Z, Mexico modifies the way of measuring inflation due to the change in consumption after the pandemic In 2019, three healthy calves were spotted, a sign that the population can and will recover if given the respite it needs.

"They're essentially the marine equivalent of an island species," said Robinson, who noted that the species has survived for tens of thousands of years with low genetic diversity. Report of the Eleventh meeting of the Comite Internacional para la Recuperacion de la Vaquita (CIRVA). In fact, Robinson said, of the 12 marine mammal species -- including vaquitas -- the researchers genetically analyzed, vaquitas had the lowest number of potentially harmful mutations.

If, however, the practice continues, even moderately, the prospects of recovery are less optimistic. The number of vaquitas is alarmingly low, as well as the speed with which the population of this mammal decreased: in 1997 it was estimated that there were just over 560 specimens, according to the International Union for Conservation of Nature, the figure dropped to 200 by 2005 and about 15 years later there are about a dozen left. This indicates that the surviving animals are still reproducing. WWF is working with the Mexican government, scientists, and other partners and collaborators to protect this unique creature.

WWF's goal is to achieve a gillnet-free Upper Gulf of California where wild vaquita can thrive. She noted that these issues have existed in the Gulf of California for decades, predating the spike in overseas demand for totoaba, and highlights the enormous challenge inherent in environmental conservation. They may have found ways to evade the gillnets that have otherwise decimated the species. Based on expert recommendations, WWF has called on the Mexican government to strongly enforce a ban on gillnet fisheries throughout the entire range of the species since September 2014. Mexican president Andrs Manuel Lpez Obrador, who oversaw a policy reversal and rolled back enforcement in the protected area has spoken out about sanctions against the Mexican seafood industry and international interventions.
