摘要
2004年3月,对湖南省桃源陬市养殖鲤鱼体内绦虫的感染进行了初步研究.发现其肠道内寄生有4种绦虫,即:中华许氏绦虫、日本许氏绦虫、短颈鲤蠢绦虫和微小鲤蠢绦虫,这四种绦虫的感染率分别为37.1%、25.7%、14.3%、11.4%;感染强度分别为2.6、2.6、1.9、20.5.体长大于24cm的鲤鱼对中华许氏绦虫和微小鲤蠢绦虫的感染率随体长增加而升高,而鲤鱼对日本许氏绦虫和短颈鲤蠢绦虫的感染率在体长为24~26cm段内为最高,大于26cm的个体则随体长增加而有所波动.四种绦虫对鲤鱼的丰满度存在显著性影响(P<0.05),感染鱼的丰满度平均下降了14.34%.
An initial research was the infection of Tapeworms in the cultural Carp Cyprinus carpio from Zou-shi town of Tao-yuan county, Hunan Province, on March 2004. The result showed that four kinds of tapeworms live in host intestines, the tapeworms: Khawia sinensis, K. japonensis, Caryophyllaeus brachycollis and C. minutus. The prevalence of four kinds of tapeworms is 37.1%, 25.7%, 14.3% and 11.4% respectively. The mean intensity is 2.6, 2.6, 1.9 and 20.5, respectively. The prevalence of Khawia sinensis and Caryophyllaeus minutus increases with the increases of host body length over 24 cm carp. But the prevalence of Khawia japonensis and Caryophyllaeus brachycollis is highest in body length 24-26 cm carp, and it has fluctuations with the increases of host body length over 26 cm carp. There is an significance influence to condition factor of Carp by tapeworms (P 〈 0.05). The infection fish had low condition factor (14.34%in average).
