Abstract

The research work was conducted to find out the seasonal prevalence of ectoparasites of carp fingerlings. Seven species of parasites viz. Trichodina domerguei , Trichodina reticulata , Chilodonella cyprini , Myxobolus koi , Dactylogyroides tripathi , Dactylogyrus extensus and Dactylogyrus catlarius were recovered from 640 fingerlings of Silver carp ( Hypophthalmicthys molitrix ), Bighead carp ( Ctenopharyngodon idella ), Common carp ( Cyprinus carpio ), Thai punti ( Puntius gonionotus ), Catla ( Catla catla ), Rui ( Labeo rohita ) and Mrigal ( Cirrhina mrigala ) from different nursery ponds of Bogra district during June 2005 to May 2006. The highest prevalence (95%) was in Trichodina domerguei and lowest (10%) in Dactylogyrus catlarius during winter season. Average prevalence of protozoan and monogenean parasite was 37.16 in rainy season, 40.08 in winter season and 30.25 in summer season. Winter is the most disease occurring season of the year. Key words: Ectoparasite, infestation, prevalence, fingerling, nursery pond Â doi:10.3329/ujzru.v27i0.1947 Univ. j. zool. Rajshahi Univ. Vol. 27, 2008 pp. 17-19

博格拉州Santaher鲤鱼鱼种体外寄生虫流行情况

本研究旨在了解鲤种体外寄生虫的季节性流行情况。从鲢鱼(Hypophthalmicthys molitrix)、鳙鱼(Ctenopharyngodon idella)、鲤鱼(Cyprinus carpio)、泰国梭鱼(Puntius gonionotus)、鲇鱼(Catla Catla)、鳙鱼(Catla Catla)、鲢鱼(Catla Catla)、鲢鱼(Catla Catla)、鲢鱼(Catla Catla)、鲢鱼(Catla Catla)、鲢鱼(Catla Catla)的640种鱼种中共检出7种寄生虫。2005年6月至2006年5月在博格拉区不同的育苗池中发现了芮(Labeo rohita)和Mrigal (Cirrhina mrigala)。冬季以多毛滴虫最高(95%)，毛虫最低(10%)。雨季原生动物和单系寄生虫平均患病率为37.16，冬季为40.08，夏季为30.25。冬季是一年中发病最多的季节。关键词:体外寄生虫，侵染，流行，鱼种，苗池Â doi:10.3329/ujzru.v27i0.1947Rajshahi university .
