摘　　要：【目的】对额尔齐斯河(中国段)河鲈(Perca fluviatilis Linnaeus)的寄生虫组成及感染情况与寄生特性进行调查研究。【方法】按照鱼类寄生虫的常规调查及研究方法,于2009年4月～2010年1月分四次对额尔齐斯河171条河鲈进行剖检,进行了对其寄生虫感染的种群生态学研究。【结果】共发现寄生虫8种,分别为鲈锚钩吸虫(Ancyrocephalus percae Eegens)、复殖吸虫幼虫未定种(Trematoda larva)、复口吸虫未定种(Diplostomulum sp.)、三枝钩绦虫幼虫(Triaenophorus Rudolphi larva sp.)、湖沼驼形线虫(CamallanusLacustris)、泡吻棘头虫未定种(Pomphorhynchus laevis sp.)、椭圆尾鲺(Argulus ellipticaudatus)、锚头鳋未定种(Lerraea cyprinacea sp.)。【结论】其中复口吸虫(Diplostomulum sp.)、三枝钩绦虫幼虫(Triaenophorus Rudolphisp.)的年感染率分别为32.75%和10.53%,为河鲈寄生虫群落的核心种。复口吸虫在体长小于10 cm的宿主种群中不感染,在体长大于10 cm的宿主种群中,呈现聚集分布。三枝钩绦虫在体长小于10 cm的宿主种群中呈现随机分布,在体长大于10 cm的宿主种群中,呈现聚集分布。[ Objective and Method ] The project aims to investigate the species composition, infection condition and parasitic characteristics of parasites of Perca fluviatilis Linnaeus in Ergis River （China） by the ascertainment method of fish parasites. By the means of routine methods of fish parasites research, we autopsied 171 Perca fluviatilis Linnaeus. [ Result] The result showed that 8 species of parasites were： Ancyrocephalus percae Eegens, Trematoda larva, Diplostomulum sp, Triaenophorus Camallanus Lacustris, Pomphorhynchus laevis sp, Argulus ellipticaudatus, Lerraea eyprina cea sp. [ Conclusion] Diplostomulum sp. and Triaenophorus Rudolphi larva infection rates were 32.75% and 10. 53%, respectively. They were the core species in the parasite community of Perca fluviatilis. The Diplostomulum sp. was not infected in host populations of less than I0 cm in body length and it displayed the aggregation distribution in the body longer than 10 cm in the host communities. Triaenophorus Rudolphi larva sp. showed random distribution in host populations of the body length of less than 10 cm, and aggregated distribution was shown in host populations whose body was longer than 10 cm.
