于2011-2012年期间,对白洋淀水域4种经济鱼类(鲫鱼、草鱼、鲢鱼、鳙鱼)指环虫(Dactylogyrus)的寄生情况进行了调查,并对指环虫的重要分类特征——中央大钩和交接器进行了显微拍照。本次调查共发现指环虫12种(其中2种为未定种),在鲫鱼上发现6种,其中美丽指环虫(D.formosus)和弧形指环虫(D.arcuatus)为优势种。鲢鱼上发现2种,鲢指环虫(D.hypophalmichthys)为优势种。鳙鱼上发现2种,鳙指环虫(D.aristichthys)为优势种。草鱼上发现2种,页形指环虫(D.lamellatus)为优势指环虫。通过调查,初步掌握了白洋淀4种经济鱼类指环虫的寄生情况,为白洋淀指环虫病的研究提供了基础资料。
During 2011-2012, the parasitism of Dactylogyrus of four species of commercial fish (crucian, grass carp, silver carp and bighead carp) in the Baiyangdian Lake was investigated. The characteristics of the central classification Hooks and connectors were photographed microscopically. In this survey, 12 species of ringworm (2 of them undetermined species) were found, of which 6 species were found in crucian carp. Among them, D.formosus and D.arcuatus were the dominant species. Two species of silver carp were found, and D. hypophalmichthys was the dominant species. Two species were found on catfish, and D.aristichthys was the dominant species. Two species were found on grass carp, D.lamellatus was the dominant finger worm. Through the investigation, we initially mastered the parasitism of the four economic fingerprinting worms in Baiyangdian Lake and provided the basic data for the research on the finger worm disease in Baiyangdian Lake.
