Totoaba Fish Life Threat: Threat To The Existence Of The World Smallest Marine Mammal Vaquita Totoaba Fish Only 10 Left

Washington: The world’s smallest marine mammal is in danger. These creatures, which came into existence 2.5 million years ago, are now on the verge of extinction, because only 10 of them are left in the world which are in the Gulf of Mexico of California. These creatures are called vaquita porpoises or totoaba fish. Researchers are looking for a way to save these creatures.

The life of the vaquitas is threatened by illegal gillnetting to catch shrimp and small fish. Their length is 4 to 5 feet, about 1.2 to 1.5 meters. These fish have a special type of bladder which is used to make traditional medicines in China, due to which they are being killed rapidly. Mexico has made the catching and use of gillnetting totoaba fish illegal. But this work is going on in full swing.

Study of samples of cells
With such a small population, researchers question whether the totoaba is at risk of extinction due to inbreeding. Scientists Barbara Taylor and Lorenzo Rojas Bracho, who have studied the risk of these organisms for 20 years, said in their 1999 study that their extinction cannot be predicted. A team of Mexican scientists is studying cell samples taken from totoaba fish between 1985 and 2017 to find genetic patterns.

Population will increase by stopping gelting
Study co-author Rojas Bracho said who knew that after so many years this sample would need to be studied. He said that if gillnetting is stopped, enough genetics have been encoded in them which can increase their population. In research published in the journal Science on Thursday, he said that if we allow these animals to live, then they will live for a long time.
