摘    要:在1991-1993年,笔者在清原县金家水库和后楼水库用敌敌畏进行了鲢小鞘指环虫病的防治试验,并对大水面防治鱼病的施药方法作了初步探索。试验结果表明,0.08-0.20ppm的敌敌畏均能有效杀灭此虫。组织病理研究发现,病鱼鳃瓣缺损,粘液增多,鳃血管扩张充血,出血,呼吸上皮肿胀。上皮细胞增生,使鳃小片融合,鳃丝呈棍棒状;相邻几条鳃丝发生融合,形成一片上皮细胞板。病状严重时,鳃小片坏死、解体。

关 键 词:鲢鱼  指环虫病    组织病理  防治

Abstract:The preliminary studies to use dichlorvos (80%) for controlling the gill dactylogyriasis (Dactylogyrus vaginulatus Zhang et Niu, 1966) of silver carp,Hypophthalmichthys molitrix (Curier et Valenciennes) in the Jinjia and Houlou Reservoirs during 1991-1993 were reported. The method to sprinkle drugs for preventing and treating the reservoir fish diseases was discussed. The results showed that dichlorvos, 0. 08-0. 20 ppm, can thoroughly kill the trematode on gill of the silver carp. The histopathological studies indicated that the gill infected by trematode were with more mucus, injured very mechanically the gill filaments congested and bled. The results also showed: the resporatory epithelium swelled; hyperplasis of epithelial cell resulted in the fusion of adjacent lamellae to form the baculiform filaments. In serious condition,adjacent gill filaments further fused and formed a piece of epithelial cell plate.
Keywords:silver carp  dactylogyriases  gill histopathology  treatment
