摘　　要：按照常规采样及研究方法,对额尔齐斯河(中国段)鱼类寄生性甲壳动物的种类组成及感染情况进行调查。结果表明,额尔齐斯河(中国段)随机抽样调查的24种鱼类中有10种感染甲壳动物,共发现12种寄生性甲壳动物,隶属于2亚纲、3目、4科、6属;额尔齐斯河寄生性甲壳动物的宿主有一定的地域特性,寄生性甲壳动物多发于夏季;感染率大于或等于10%的有鲢中华鳋(Sinergasilus polycolpus)和鳋未定种(Ergasilidae sp.);除个别虫种外,额尔齐斯河鱼类寄生性甲壳动物的感染率及感染强度均不高。The parasitic crustaceans of fishes in Ergis River of China were investigated from 2009 to 2013.Twenty-four species of fish,collected randomly from Ergis River,were examined.The species composition,prevalence and infection intensity of fish parasites were shown as follows：total of 12 species of parasitic crustaceans belong to 6 genera,4 families,3 orders,2 subclasses were found in 10 fish species.The parasitic infection in host was charac-terized by geographical features and seasonal variation,with the highest prevalence,infection intensity and species richness of parasitic crustaceans all observed in summer.The prevalence and infection intensity of each parasite species was low,except for crustaceans Sinergasilus polycolpus and Ergasilidae sp.,with the relatively higher prev-alence（≥10%）.
