摘　　要：[目的]探究大洋河丹东段鱼类资源。[方法]于2021年12月至2023年6月对该流域鱼类资源进行了4次调查。[结果]共采集鱼类38种,隶属于10目15科37属。其中以鲤形目最多,共计2科22属23种,占60.53%;其次为鲈形目4种,共计4科4属,占10.53%;鲇形目、胡瓜鱼目与鲻形目均2种,占5.26%;七鳃鳗目、鳗鲡目、鲱形目、鲉形目、鲀形目各1科1属1种,均占2.63%。从鱼类生态类型来看,鱼类群落以底层、产黏性卵、杂食性鱼类为主。渔获物数量组成中以似鮈、宽鳍鱲与鸭绿沙塘鳢占比较高,分别为16.37%、12.10%、9.79%。[结论]该研究补充了大洋河丹东段鱼类资源现状的基础数据,为该河流鱼类资源管理与生态评估提供科学依据。[Objective]In order to explore the fish resources in the Dandong section of the Dayang River.[Method]Four surveys of fish stocks in the basin were conducted between December 2021 and June 2023.[Result]The results showed that a total of 38 species of fish were collected in this survey,belonging to 10 orders,15 families and 37 genera.Among them,Cypriniformes were the most numerous,with a total of 23 species in 2 families and 22 genera,accounting for 60.53%;followed by 4 species of Perciformes,with a total of 4 species in 4 families and 4 genera,accounting for 10.53%;and 2 species of Siluriformes,Osmeriformes and Mugiliformes,accounting for 5.26%;among them,Petromyzoniformes,Angulariformes,Petromyzoniformes and Mugiliformes were the most numerous.Among them,Petromyzoniformes,Anguilliformes,Clupeiformes,Scorpaeniformes and Tetraodontiformes each had one species of one family and one genus,accounting for 2.63%.In terms of fish ecotypes,the fish community was dominated by demersal,slimy egg-laying,omnivorous fish.The catch composition was higher for Pseudogobio vaillanti,Zacco platypus and Odontobutis yaluens,with 16.37%,12.10%and 9.79%,respectively.[Conclusion]This study supplements the basic data on the status of fish resources in the Dandong section of the Dayang River,in order to provide scientific basis for the management and ecological assessment of fish resources in this river.
