Abstract: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 were collected, which were identified as 34 species belonging to 27 genera, 8 families and 3 orders. There were 20 genera including 24 species in Cypriniformes, 6 genera including 8 species in Siluriformes, and 1 genus including 2 species in Siluriformes. 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 protected animals in Sichuan province, and 9 were endemic to upper reaches of the Yangtze River. In addition, S.(Racoma)davidi was listed as endangered (EN), and S.(S.)prenanti and Liobagrus marginatus were listed as vulnerable (VU) in the Red List of China’s Vertebrates. Most of the fish species living in the Zhougong River now were small-sized. Among them, Abbottina obtusirostris and Zacco platypus were dominant. Dam constructions on the Zhougong River might have resulted in negative impacts on fishes.
