摘要
对黄鳝体内寄生虫感染情况进行了研究。结果表明,黄鳝体内寄生虫主要为毛细线虫和新棘衣棘头虫;毛细线虫的感染率为18.6%～76.2%,平均54.2%,感染强度为1.2～5.1,平均4.3;新棘衣棘头虫的感染率为27.9%～86.5%,平均70.8%,感染强度为6.8～22.3,平均17.1,两种寄生虫对黄鳝的感染率和感染强度均随黄鳝体长的增大而增大。新棘衣棘头虫和毛细线虫在黄鳝体内呈聚集分布,但其寄生对黄鳝的肥满度没有产生明显的影响。
Parasitic infection of Monopterus albus was investigated in this paper. The results were as follows： there were two species of primary parasitics：Eustrongylides sp and Pallisentis （Neosentis） celatus.the prevalence of Eustrongylides sp was 18.6%-76.2%,the mean prevalence was 54.2%.the infection intensity of Eustrongylides sp was 1.2-1.5,the mean infection intensity was 4.3,pervalence and infection intensity increased with the growth of M.albus. The prevalence of Pallisentis（Neosent/s） celatus was 27.9%-86.5%,the mean prevalence was 70.8%.the infection intensity of Pallisentis （Neosentis）celatus was 6.8-22.3,the mean infection intensity was 17.1 ,pervalence and infection intensity of Pallisentis （Neosentis） celatus also increased with the growth of M.albus.they both showed aggregated distribution,but fatness of M.albus was not correlated with the speeices and infection intensity of the parasites signifcantly.
