By the method of clinical survey and full parasitological dissection 268 copies of a black amour had been surveyed. Intensity of infection with the elementary parasites (Ichthyophthirius, Trichodina and etc.) defined the relative number in sight a microscope, and intensity of trematodes, monogeneas infection, tape worms - by absolute quantity of parasites in one fish. For the period of research at a black amour 4 kinds of parasites are revealed: infusorians -2, monogeneas -1, trematodes -1. Parasitic fauna of a black amour is poorest in a qualitative sense and is presented basically by parasites with a direct cycle of development. From parasites with a complex cycle of development in a black amour metacircaria trematod Diplostomum are registed individually at 20 % of the investigated fishes. Results of the conducted researches give the basis to consider that in conditions of polyculture the black amour is susceptible to infection with activators of invasion illnesses which are characterized for pond fishes
