| 中文摘要: |
| 通过对额尔齐斯河粘鲈（Acerina cernua）的取样调查研究,揭示了其感染复口吸虫（Diplostomum）的种群生态学的部分特点。2009年4月至2013年4月随机选取额尔齐斯河河段内的北屯、哈巴河为采样点进行采样调查。共采集解剖体长5～13cm粘鲈129尾。结果表明，复口吸虫的总感染率为38.76%，平均感染强度为16.06±30.85，感染0、1～5、6～10、11～15、16～20和20只以上复口吸虫的粘鲈占粘鲈总数的比率分别为61.24%、24.03%、3.88%、1.55%、1.55%和7.75%。复口吸虫感染率和感染强度随着粘鲈体长的变化而发生变化：感染率在13 cm以上的粘鲈中达到最大，为80 %；平均感染强度在11cm≤L＜13cm范围内最大。感染强度在体长段5cm＜L≤7cm与9cm＜L≤11cm 和11cm＜L≤13cm之间存在显著性差异。复口吸虫种群在宿主不同体长段中的分布类型均为聚集分布,且聚集强度随宿主体长的变化而发生变化。

| The population dynamics of Diplostomum infection in Acerina cernua in Ergis River were determined by means of field sampling and investigation. A total of 129 fish (5-13cm) collected from Beitun and Habahe of Ergis River was studied from April 2009 to April 2013.The results showed that the prevalence of Diplostomum in Acerina cernua was 38.76%, and the average intensity of infection was 16.06±30.85. Acerina cernua, classified according to the number of Diplostomum infecting per fish(0, 1-5, 6-10, 11-15, 16-20, ﹥20 ), accounted for 61.24%, 24.03%, 3.88%, 1.55%, 1.55% and 7.75% of the total fish, respectively. The prevalence and intensity of infection varied with the length of Acerina cernua. The highest infection prevalence of Diplostomum (80%) was in size class﹥13 cm and the highest mean intensity of infection occurred in size class of 11cm＜L≤13cm, Significant difference in the infection intensity was observed among the three size classes: 5cm＜L≤7cm, 9cm＜L≤11cm and 11cm＜L≤13cm. In conclusion, the population of Diplostomum was characterized by aggregation distribution in different host length groups and the aggregation intensity was closely related to the host size. |
