The International Union for the Conservation of Nature and Natural Resources ( IUCN ) released the latest edition of the Red List of Threatened Species in the World, declaring that the Yangtze sturgeon (Acipenser dabryanus) has changed from critically endangered to wild extinction , and confirmed that the white sturgeon (Psephurus gladius) has become extinct.
White sturgeon is one of the largest freshwater fish in the world. It is listed as a national first-class protected wild animal in my country and was once listed as a “critically endangered” species by IUCN. In early 2020, the team of Wei Qiwei, chief scientist of the Chinese Academy of Fishery Sciences, published a paper on the extinction of the white sturgeon.
According to the IUCN official website, all 26 species of sturgeon in the world are at risk of extinction.
