Abstract
In order to understand the current status of fish diversity in autumn in the Jiayin section of the Hei-longjiang Main Stream,two 10-day surveys were conducted at Taiping Village and other beachlands in the Jiayin section of the Heilongjiang Main Stream from September 11 to October 30,2024.A total of 1 175 fish species be-longing to 5 orders,9 families and 28 genera were found,with a total weight of about 68.68 kg,with an average weight of 34.55 fish per net and 2.02 kg per net.In the first survey,Hemibarbus labeo,Gobio cynocephalus,Gobio tenuicorpus,Culter alburnus and Silurus asotus were the dominant species.There is a trend of miniaturization of dominant species.The dominant species in the second survey were Brachymystax lenok and Thymallus tugarina from the lower Heilongjiang Huso dauricus is a common species in both investigations,and Huso dauricus is a com-mon species and a young sturgeon,indicating that its resources have recovered somewhat.The diversity index ran-ges from 1.88 to 2.0,which is generally low.关键词
