The present study has been carried out to find out the prevalence of ectoparasites of carp fingerlings during different months of the year 2008-2009. Four groups of ectoparasites viz. myxozoan, ciliophoran, monogenean and crustacean were recorded from 400 fingerlings of Rohu (Labeo rohita), Catla (Catla catla), Mrigal (Cirrhinus mrigala), Bata (Labeo bata), Common carp (Cyprinus carpio) and Lata (Channa punctatus) collected from different ponds of Nadia and Hooghly district of West Bengal from June 2008 to May 2009. The highest prevalence (51.66%) of infection has been recorded in ciliophorans and the lowest was in crustacean (17.5%) between the months of December and February. The highest ectoparasitic prevalence (36.85%) was recorded during winter season (December-February) while the lowest prevalence (9.16%) recorded during rainy season (June-August).
本研究旨在查明2008 - 2009年不同月份鲤鱼鱼种体外寄生虫的流行情况。从西孟加拉邦纳迪亚和胡格利区不同池塘采集了400尾印度魮（Labeo rohita）、印度鯝（Catla catla）、黑鰮（Cirrhinus mrigala）、野鲮（Labeo bata）、鲤（Cyprinus carpio）和月鳢（Channa punctatus）鱼种，记录了四类体外寄生虫，即粘孢子虫、纤毛虫、单殖吸虫和甲壳类动物。2008年6月至2009年5月期间，12月至2月间纤毛虫的感染率最高（51.66%），甲壳类动物的感染率最低（17.5%）。冬季（12月至2月）体外寄生虫感染率最高（36.85%），雨季（6月至8月）感染率最低（9.16%）。
