The Yangtze River White Sturgeon has Become Extinct
According to the Red List of Threatened Species updated by IUCN on July 21, the Yangtze River white sturgeon has become extinct.
In December 2019, experts from the Yangtze River Fisheries Research Institute of the Chinese Academy of Fishery Sciences published a research paper in the international academic journal "Total Environmental Science" and pointed out that the Yangtze River white sturgeon are expected to be extinct from 2005 to 2010.
White sturgeon is a species endemic to the Yangtze River and is known as the "king of freshwater fish in China". It is one of the very few ancient fish that survived the Cretaceous period 150 million years ago and is a national first-class protected wild animal. The Yangtze river white sturgeon is 2 to 3 meters long and weighs 200 to 300 kilograms. It mainly lives in the main and tributaries of the Yangtze River below Yibin. The longest body is 7 meters long.
In 2003, the white sturgeon appeared in the human vision for the last time in the Nanxi section of the Yangtze River in Yibin. "A thousand jins of larvae and ten thousand jins of elephants," said Wen Chengguan, a finless porpoise protection volunteer. It was announced in a research paper before, but now it is officially confirmed by the International Union for Conservation of Nature that the Yangtze river white sturgeon has really left forever.
