Chinese paddlefish
The Chinese paddlefish (Psephurus gladius) (simplified Chinese: 白鲟; traditional Chinese: 白鱘; pinyin: báixún), also known as Chinese swordfish, is an extinct species of fish that was found in Yangtze and Yellow River basins in China. They had an average length of 3 m (9.8 ft),[1] making it one of the largest species of primarily freshwater fishes.
The Chinese paddlefish was officially declared extinct in July 2022, with an estimated time of extinction to be by 2005–2010, although it had become functionally extinct by 1993.[2] The main cause of its extinction was the construction of the Gezhouba and Three Gorges dams.[3]
