| 摘 要： | 在湖泊的渔业生产中,乌鳢一般是作为敌害鱼类被加以清除的。通过渔获物调查和对乌鳢种群结构和食物组成的分析,认为在花园湖现有的生态条件下,乌鳢对经济鱼类的危害不大,还能起到抑制小杂鱼过量繁殖的作用,可以作为特种经济鱼类予以保留。

| Abstract: | In the production of lake fishery Ophiocephalus argus Cantor isgenerally eliminated as a kind of harmful fish, because it feeds on fishes. Afterfishing products of Huayuan lake have been investigated, the population structureand the food composition of O. argus have been analysed. It is considered that thefish may be reserved as a kind of specially utilizable fish for native people underpresent ecologic conditions of Huayuan lake, because ii is not much harmful toother commercial fishes in the lake and can also restrain mass reproducing ofsmall wild fishes which are main food of O. argus |
