黄鳝体内胃瘤线虫的种群生物学研究
POPULATION BIOLOGY OF EUSTRONGYLIDES SP.IN THE HOST FINLESS EEL MONOPTERUS ALBUS

摘要: 胃瘤线虫幼虫主要寄生于黄鳝的体腔内,以包囊形式附着于肠壁及肠系膜等处.该线虫的感染率和感染强度有随宿主体长的增加而增加的趋势,但有些波动,在体长30-400mm的黄鳝中其感染强度先有所下降,后又迅速增加,体长40mm以上的黄鳝其感染率降低.这可能宿主鱼的食性改变及对寄生虫的感染产生免疫力等有关.胃瘤线虫的种群平均丰度随宿主体长的增加而缓慢地增加,其种群平均丰度(M)与宿主体长(L)符合直线方程M＝-1.0760+0.008L的变化规律.随着黄鳝体长的增加,胃瘤线虫种群在黄鳝中的频率分布的尾增长,即黄鳝感染较多线虫所占的比例增加.4-月份黄鳝体内的胃瘤线虫种群组成中以体长较大的虫体(40-60mm)为主.胃瘤线虫种群在宿主黄鳝种群中呈聚集分布,且聚集强度随线虫种群平均丰度的增加而增加.Abstract: The larva of Eustrongylides sp.is mainly found in the cavity of finless eel Monopterus albus.It is wrapped in a capsule that attaches on gut and mesentery etc.Prevalence and intensity have a tendency of increases with the increases of host body length,but it has a fluctuation.Mean intensity drop first and increases follow in finless eel of body length 350—400mm,prevalence falls in finless eel of body length more than 450mm.The change is probably related to the feeding differentiation of finless eel and the immune response of host fish infected by the nematode(larva).Abundance increases lineally with the increases in host body length.The relationship between mean abundance(M)of parasite population and body length(L)of host fish are:M=-1.0760+0.0085L.The end of frequency distribution of the nematode population in host population lengthens with the increases of host body length.The range of the nematode(larva)body length are 10—70mm,but their body length are mostly 40—60mm in host population,in April to May.The over-dispersion of parasite population in host population was observed,and the degree of the aggregation increases with the increase in mean abundance.
