Chinese sturgeon (Acipenser sinensis Gray), a class I
endangered species by the Chinese government (Wei

only remains in the Yangtze (Changjiang) River,
China (Hubei Institute of Hydrobiology 1976). Adult
Chinese sturgeon, which are a maximum of 400 cm
total length (TL) and 452 kg body weight (BW), are
one of the largest fish to enter fresh water (Chang and
Cao 1999).
