摘要
2004年3月-2005年7月对抚仙湖鱼类资源进行了调查,共采集到鱼类33种,隶属于13科30属,其中土著鱼类14种,特有鱼类4种.渔获物种类主要为:太湖新银鱼、云南倒刺鲃、抚仙鲇、黄颡鱼和鲫等.抚仙湖鱼类群落结构发生了显著变化,鱇浪白鱼等土著鱼类资源严重衰竭.与1995年相比,11种土著鱼类未采到,其他鱼类增加5种.
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 taihuensis Chen, Spinibarbus yunnanensis Tsu, Silurus graharni (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 the survey of fish species made in 1995, 11 indigenous species were not collected in Lake Fuxian, while 5 species were found at first.
