Abstract:
A total of 37 species of fishes belonging to 32 genera and 15 families were collected and identified in Lake Fuxian from March 2004 to July 2005. Among them, 14 species belonged to indigenous fishes and 4 species were endemic to this lake. The main fishes in the catch were Neosalanx taihuefisis Chen, Spinibarbus yunnanensis Tsu, Silurus grahami (Regan),Pelteobagrus fulvidraco ( Richardson) and Carassius auratus auratus ( Linnaeus). There were great changes on community structure of fish fauna in Lake Fuxian,and the resources of the indigenous fishes such as Anabarilius grahami (Regan) decreased severely. Compared with ihe survey of fish species made in 1995,11 indigenous species were not collected in Lake Fuxian, while 5 species were found at first.
Key words:  Fish resources  indigenous fishes  status of resources  Lake Fuxian
