Introduction Vaquita porpoises have a rapidly decreasing population. They have been becoming endangered from dangerous techniques of fishing. Humans have made many efforts to raise awareness. This is how humans can help the Vaquitas from becoming extinct.
Body

The Vaquita porpoise is the world’s smallest, and most endangered marine mammal. The Vaquita is located mainly in the Sea of Cortez in Mexico, in the Gulf of California. They normally live in groups with two to three Vaquitas in them. Vaquita in Spanish means, “little cow,” in Spanish. In 2012 the CIRVA estimated 200 vaquitas remained, now it’s estimated less than 30 remain. Since 1997 92% of the Vaquita population has decreased. Less than 25 of Vaquitas that still remain are female. Which has a major impact on the Vaquita population. The Species that will be affected are benthic fish, and crustaceans which are Vaquita’s main prey. …show more content…
In fact Vaquitas weren't discovered until 1958. Every year the Vaquita population mortality rate increases. The main cause of mortality for them is fish and shrimp nets. They get trapped in the nets, and can’t escape, and then end up drowning. One of this biggest issues to this is the illegal fishing of the Totoaba fish. It's illegal to catch and sell, and often sells for 8,500$. The net they use to catch theses fish is the biggest threat to vaquitas. Humans have helped, and not helped the Vaquita in many ways. Ever since 1961, Vaquitas have been getting caught in fishing nets. It's showing that 1 out of 5 Vaquitas get caught, and entangled in gillnets. The president of Mexico has banned gillnets, it is illegal to fish with them, and transport them. Many fisheries in Mexico and California have closed to make efforts to save the Vaquita. This law is mandatory, but it’s not going to last long. It's only in effect for two

Vaquita Research Paper

...The vaquita is now the most critically endangered small cetacean in the world. In 2006, its population was estimated at 400 (Blackwell, 2006). But more recently, its population size is estimated to be only about 200, further declining every year (Kirby, 2012). While genetic analyses and population simulations initially suggested that the vaquita has always been rare and that its population reduction has occurred over evolutionary time, it has more recently been discovered that its mortality rate is due to anthropogenic factors. Other hypotheses for the decline in the vaquita population that have been studied are that the water flowing from the Colorado River was polluted which decreases the flow of freshwater, or that the mortality rate is a product of inbreeding (D’agrosa et al. 2000). However, the biggest reason for the decline of vaquitas living in the temperate waters of the Gulf of California is that they are simply victims...
