据目前所知,单殖亚網吸虫中的枝环虫属Dactylogyrus,有不少种类是淡水魚类鳃瓣病的病原体,常造成幼魚大量死亡,因此,了解不同淡水水域的魚类寄生枝环虫的种类組成,对进行魚病防治工作具有一定意义。作者于1960年2月至1961年3月,在蕪湖市裕溪口水产养殖場,对我国有悠久养殖历史的家魚,即青、草、鰱、鳙的寄生枝环虫进行了初步的种类调查。调查所获标本,經鉴定共有九种。除其中一种,作者认为是新种,拟定名为蕪湖枝环虫D.Wuhuensis Lee Sp.nov.,1960,已有专文报道外(注)。其余八种則与郎所等(1958—1960年)在太湖所报道的相同,这就是:頁形枝环虫D.lamellatus achmerow,1952;大钩枝环虫D.magnihamatus achmerow,1952;鲩枝环虫
To date, many species of Dactylogyrus in the genus Trichinella are the pathogen of freshwater fish gill flap disease and often cause large numbers of juvenile deaths. Therefore, it is important to know the parasitic fury of fish in different freshwater waters Of the species composition, for the prevention and treatment of fish disease has a certain significance. The author from February 1960 to March 1961 in Wuhu City Yuxikou aquaculture farms, our country has a long history of aquaculture fish, namely, green, grass, silver carp, parasitic monkeypox were preliminary species survey. The specimens obtained by the investigation, identified a total of nine species. Except for one species, the author considers it as a new species, which is called D. Wuhuensis Lee Sp.nov. The remaining eight are the same ones reported by Taiwanese and others (1958-60) at Taihu Lake: D. lamellatus achmerow, 1952; D. magnihamatus achmerow, 1952; Central worm
