The aim of this study was to confirm the taxonomic status of Bielecki, 1994 found on Salmonidae fish. The fish leech was identified based on a diligent morphological analysis as well as COI gene sequence (DNA barcoding). The phylogenetic relationship with other piscicolid leeches was analyzed as well. was found on various fins of both graylings and the resident form of trouts. The prevalence of infection was 1.63%. In this paper, probable causes of the lack of relation between the number of leeches on the fins and the fish body length as well as the host-searching strategy used by are discussed.
本研究的目的是确认1994年在鲑科鱼类上发现的比氏蛭属的分类地位。通过细致的形态学分析以及细胞色素氧化酶亚基I（COI）基因序列（DNA条形码）对这种鱼蛭进行了鉴定。同时还分析了它与其他鱼蛭科水蛭的系统发育关系。在河鳟和定居型鳟鱼的各种鱼鳍上都发现了这种水蛭。感染率为1.63%。本文讨论了鱼鳍上水蛭数量与鱼体长度之间缺乏关联的可能原因以及该水蛭所采用的宿主搜索策略。
