Abstract：In order to understand thecurrent situation of fish resources inthe Chujiang River and protect them effectively，gillnets and ground cage nets were used to collect fish at four sampling points in the Chujiang River basin in September 2018，May 2019 and April 2020，respectively.According to the survey，20 fish speciesare found，belonging to3orders，4 families and19 genera.Among them，Cypriniformes has the largest number of species，with a total of 18 species，accounting for 90% of the fish species in the Chujiang River.There are 1 species of Siluriformes and 1 species of Perciformes，each accounting for 5% of the fish species.The Shannon-Wiener diversity index of fish resources in the Chujiang River is 2.37，the Pielouevenness index isO.79and the Margalef richness index is 3.40.Theresults showlow richness of fish species and asmall number of fish catches in the main stream of the Chujiang River.Therefore，the resource prospect is not optimistic.It is recommended to strengthen fishery management，conduct environmental impact assessments，and carry out measures like stock enhancement.

邱江河是南河的一级支流，岷江的二级支流[1，发源于大邑县西部山区，有南、北两大河源，北源名叫小河子，南源名叫大飞水，大飞水与小河子在西岭镇汇合后称为邱江河，流经花水湾镇、邮镇、新场镇，在新场出山谷后进入川西平原，折向南流，流经桑园镇，在邛崃市城西汇入南河。（剩余7105字）
