摘　　要：为了解长江上游青衣江一级支流周公河的鱼类资源现状,于2015年4月—2016年2月对周公河18个采样点进行了5次调查,共采集鱼类4 924尾,隶属于3目8科27属34种。其中,鲤形目Cypriniformes 20属24种,鲇形目Siluriformes 6属8种,鲈形目Perciformes 1属2种;鲤形目中鲤科Cyprinidae鱼类最多,共15种,占总种数的44. 12%。四川省重点保护鱼类有重口裂腹鱼Schizothorax (Racoma) davidi 1种,长江上游特有鱼类9种,列入《中国脊椎动物红色名录》的鱼类有重口裂腹鱼(濒危EN)、齐口裂腹鱼S.(S.) prenanti (易危VU)和白缘Liobagrus marginatus(易危VU)。周公河现有分布的鱼类以小型种类为主,钝吻棒花鱼Abbottina obtusirostris和宽鳍Zacco platypus为优势种。梯级水电开发可能对周公河鱼类资源造成了不利影响。Fish resources in the Zhougong River were surveyed at 18 sampling sites for 5 times from April 2015 to February 2016.A total of 4 924 individuals belonging to 34 species,27 genera,8 families and 3 orders were collected and identified.There were 20 genera including 24 species in Cypriniformes,6 genera including 8 species in Siluriformes,and 1 genus including 2 species in Perciformes.The number of species in Cyprinidae was the largest,which occupied 44.12%of the total species number.Among the 34 species,Schizothorax(Racoma)davidi was one of the key protected animals in Sichuan province,and 9 were endemic to the upper reaches of the Yangtze River.In addition,S.(Racoma)davidi was listed as endangered,and S.(S.)prenanti and Liobagrus marginatus were listed as vulnerable in Red List of China s Vertebrates.Most of the fish species living in the Zhougong River were found to be small-sized,and among of which,Abbottina obtusirostris and Zacco platypus were the dominant.Dam constructions on the Zhougong River might have resulted in negative impacts on fishes.
