摘要
河鲈锚首虫Ancyrocephalus mogurndae是主要寄生于鳜鱼Siniperca spp.鳃上的一种单殖吸虫,此虫严重危害鳜鱼苗种,流行于珠江三角洲地区.2011年9月至2012年8月,对广东省肇庆市池塘养殖斑鳜Siniperca scherzeri寄生的河鲈锚首虫进行了一周年的种群动态研究,共检查斑鳜322尾.结果显示：斑鳜河鲈锚首虫的感染率在春夏两季较高,秋季较低,年均感染率为91.2％,其中有6个月达到了100％.其平均感染强度和平均丰度无明显的周年变化;感染率、平均感染强度和平均丰度与水温没有明显的相关关系,但河鲈锚首虫的感染强度与斑鳜的肥满度之间存在极显著的负相关关系.
Ancyrocephalus mogurndae （Yamaguti, 1940） Gussev, 1955 mainly parasitizes on the gill of golden mandarin fish, Siniperca spp. which is prevalent in pearl river delta region and caused seriously damage to larvae. The population dynamics of A. mogurndae on the gills of pond-cultured golden mandarin fish, S. scherzeri from Zhaoqing, Guangdong Province were investigated from September 2011 to August 2012. Total of 322 fish were examined. The results show that the average prevalence was 91.2% throughout the study period, and prevalence attained 100% in six months. The prevalence was slightly higher in spring and summer and lower in autumn. The annual variation of mean abundance and intensity were not significantly, and the prevalence, mean intensity and abundance were not correlated with water temperature. There was highly significant negative correlation between the intensity of the A. mogurndae and the fatness of S. scherzeri.
