新疆额尔齐斯河江鳕墨氏复口吸虫种群动态研究
Research on Population Dynamics of Lota lota's Diplostomum mergi in the Irtysh River, Xinjiang
摘要
Abstract
[Objective] The aims to reveal population dynamics of Lota lota's intraocular parasitic Diplostomum.Mergi in Irtysh River (China).[Method] which was investigated by routine survey and statistical methods of fish parasites.[Result] The total infection rate was 79.4％ and the mean infection intensity was 14.83 ± 13.56.The infection rate of different body length groups increased linearly with the host length,while the mean infection intensity and the mean infection abundance presented the first increase and then decrease trend.[Conclusion] The special state of parasitic infection and the aggregation distribution of the parasite population in the host population indicated that the parasite had the lowest impact on the host population structure.The special fish species in the Irtysh River,lota lota compared with other fish species was more susceptible to Diplostomum,and the infection rate with the host body length and age was proportional.The mean infection intensity had significant differences between the two groups (L≤20 cm,25 cm ＜L≤30 cm,30 cm ＜L≤35 cm) at (P ＜0.05).关键词
