China has for the first time successfully bred a third filial generation of Chinese sturgeon entirely through artificial propagation. The sturgeon were born from the parent fish of a 13-year-old female and 14-year-old male — both second filial generation sturgeon, demonstrating that second filial generation sturgeon can mature fully and reproduce under artificial conditions. Endemic to China, the Chinese sturgeon is a rare migratory fish and one of the most primitive extant species, often described as a "living fossil." The first filial generation of Chinese sturgeon was bred from wild parent fish in the 1980s, producing the second filial generation successfully in 2009.
