But today they face many risks and a lot of species are under threat of becoming extinct. The most endangered of all cetaceans is also the smallest of them all. An adorable looking poor POIs called the Paquita.
My mum, who has a PhD in marine biology, has kindly made a video about these animals this week to be uploaded on my birthday, so I’d, have less work to do, and also because I really love cetaceans. She has a channel of her own that you should definitely subscribe to if you enjoyed this video all about the various conservation issues that face our world today, so let’s.
Have a look at the plight of the Paquita. The Paquita is the cutest porpoise I’ve ever seen. Pictures of it is also the smallest and most threatened of the world’s, cetaceans reaching 1.2 to 1.5 meters in length.
It is only found in the northern part of the Gulf of California in an area just 2235 square kilometers, preferring the shallow water along the shoreline. The population has been monitored with passive acoustic detectors every summer from 2011 to 2018, and it is estimated that, as of summer 2018, there are fewer than 19 BEC eaters left alive.
It is estimated that there has been a total population decline since 2011 of 98.6 %. The reason they have become critically endangered is because they get trapped in the nearly invisible and illegal gill nets, gill nets and nets that hang vertically and catch fish by their gills.
These gill nets are used illegally to catch the endangered to Toba and also used by small fishing vessels for shrimp and fin fish, the Bucky to suffer horrific injuries due to the Nets cutting into them, and they drown of the documented 128 makitas from 1985 to 1992.
65 % were caught into Toba nets, commercial fishing for two Toba began in the 1920s, but in 1975 it was placed on the Mexican endangered species list and it became illegal to catch two Toba. However, the practice continues and has even boomed since 2010, due to new and lucrative illegal trade with China, the two Topaz swim bladders, the swim bladders are thought to help with a range of ailments from liver disease to arthritis.
They can be solved for as much as a hundred thousand dollars on the black market. The demand for the bladders is so high that it has proved impossible to control with criminal organizations now controlling the de tober fishery.
In 2008, Mexico implemented a recovery plan for the vaquita that included a fishing ban inside the Bucky refuge and a reduction of fishing with gill nets. However, fishing income is critical to the economy of the two villages adjacent to the range of the species.
To help these communities there was compensation for the fishermen. In spite of these nets being banned in June of 2017, the fajitas are still being killed by them. The ongoing presence of illegal gill nets, despite the emergency band, continues to drive the bike heaters towards extinction.
A monitoring study of poquito numbers began in 2011 since that time numbers have declined by nearly 99 % and by almost 50 % annually. Since 2016. There was an attempt to capture up to 12 of the perc heaters in order to keep them safe in a temporary sanctuary and then release them in part of the Gulf that had been cleared of gill nets.
An illegal fishing activity for trained US Navy, dolphins, acting like herding dogs, were to help Corral them in Nets. The conservationists knew this was going to be risky as porpoises unlike dolphins, tend to be very sensitive and are hard to keep in captivity.
However, they were hopeful. There had been recent success in the captive breeding of harbor porpoises that had been rehabilitated after being tangled in Nets or stranded. Unfortunately, in November 2018 the first captured animal was released almost immediately because it was showing signs of stress.
A second animal died after being released into the sea pen. Attempts have been made to release it, but it died before it could be freed. As far as I can tell, this project has been abandoned. The most recent research I could find, but the numbers of the vaquita was published in july 2019, using data gathered in august 2018.
At this time, the scientists estimated that at the most there were 19 fajitas left the poem we hope the vaquita z’was to guard the remaining individuals during the 2018 to 2019 to Toba spawning season, which is from December through May and remove any Illegal gill nets from the area I can’t find any information on whether this has been achieved or not.
Some positive news is that the remaining animals are in good health and have two cars. There is also evidence that the Keita & # 39. S could carve annually rather than buy only as originally thought. This gives optimism for recovery if the killing could be halted immediately.
Ie clea wait for more information on the fate of the makitas and hope they survive. The 2018 to 2019 to topaz spawning season. It would just be too sad to see these dear little creatures go extinct. I really hope you enjoyed this slightly different video and hopefully it’s been able to bring some awareness to this tragic conservation issue.
