| 摘 要： | 棱鮻(Liza carinatus)样品于2000年12月～2001年10月取自广东湛江.按常规方法从鱼鳃上挑取小钩鲻鱼虫(Ligophorus hamulosus),进行压片、计数.结果显示:随着宿主体长的增长,小钩鲻鱼虫种群的平均密度、平均感染强度呈上升趋势;从12月到次年4月,其平均密度和平均感染强度上升,随后呈下降趋势,8月最低.10月略有回升;小钩鲻鱼虫种群在不同大小的宿主上和在不同季节均呈聚集分布.

| Abstract: | Ligophorus hamulosus was collected from the gills of Liza carinatus,which were captured in Zhanjiang,Guangdong Province from Dec,2000 to Nov.2001.The routine Parasitology methods were adopted in the study.The results showed that the abundance and the mean intensity of L.hamulosus population were increased with the increase of body length.From Dec.towards next Apr.the abundance and the mean intensity was increased,and afterwards they declined the lowest in Aug.but in Oct.they were increased slightly.The prev... |
