Component communities of parasites of Thymallus thymallus and Phoxinus phoxinus are described. The communities differ in the number of species and in the number of dominate species, which is one in P. phoxinus and usually two in T. thymallus. In the first case the dominate species is allogenic, while in the second case dominate species are autogenic. Values of the species diversity indexes are also different for these communities. The differences between parasite communities of T. thymallus and P. phoxinus underline positions of these hosts in hydrobiocenose. Species specialists take first place in the parasite communities both of the hosts, that is characteristic for the parasite communities of the fishes from the boreal submountain faunistic complex. Parasite communities in both of the hosts consist of three groups of species discriminated by the ratio of their biomasses, that suggests forming of the groups by a coordination of the species biomasses.
描述了茴鱼和雅罗鱼的寄生虫组成群落。这些群落的物种数量和优势物种数量有所不同，雅罗鱼的优势物种数量为1种，茴鱼通常为2种。在第一种情况下，优势物种是异体的，而在第二种情况下，优势物种是自体的。这些群落的物种多样性指数值也不同。茴鱼和雅罗鱼寄生虫群落之间的差异突出了这些宿主在水生生物群落中的地位。物种 specialists 在这两种宿主的寄生虫群落中都占首位，这是北方亚高山动物区系复合体鱼类寄生虫群落的特征。两种宿主的寄生虫群落都由根据生物量比例区分的三类物种组成，这表明这些物种的生物量是协调形成这些类群的。
