摘要

本研究旨在了解淡水鲶鱼原生体外寄生虫的流行程度和强度。从294条鱼类中共采集到4种原生动物寄生虫。在2020年7月至2021年6月的研究期间，共观察到3种体外寄生虫。除虫中以鱼蛾属(Ichthyoptherius)最多，其次为毛虫属(Trichodina)和粘虫属(Myxobolus)。感染鱼中，外寄生虫数量最多的是阿图鱼(48.43%)，其次是乌姆波达鱼(40.27%)、cavasius(37.93%)和vittatus(32.78%)。这些寄生虫的存在阻碍了寄主鱼类的生理活动，延缓了寄主鱼类的发育生长，给渔业造成经济损失

POPULATION DYNAMICS OF PROTOZOAN ECTOPARASITES IN SOME CAT FISHES INHABITING DOMRI RESERVOIR, BEED DISTRICT (M.S.)

The present study was conducted to find out the prevalence and intensity of protozoan ectoparasites of freshwater catfishes. Total four species of protozoan parasites were collected from 294 fishes. Total three ectoparasites were observed during study period, July 2020 to June 2021. Among the ectoparasites, Ichthyoptherius is the most prevalent ectoparasites followed by Trichodina and Myxobolus. Among the infected fishes, Wallago attu (48.43%) harboured maximum number of ectoparasites followed by Ompok pabda (40.27%), Mystus cavasius (37.93%), and Mystus vittatus (32.78%). Due to the presence of these parasites, the physiological activities of the host fishes are hindered and their developmental growth is retarded which cause economic loss to the fishery industry
