[Parasitic fauna of fishes in the "Chilu-chor Chashma" Spring (Tadzhik SSR) with a constant and high water temperature].

The spring Chilu-Chor Chashma (forty four springs) is situated in the south of Tadzhikistan. In this water body water temperature is constant in any season of the year (18 to 20 C). Ichthyofauna is represented by three species: Varicorhinus heratensis Steindachneri, Alburnoides bipunctatus eichwaldi and Cyprinus carpio. As a result of parasitological studies 20 species of parasites were recorded from 129 fishes. The parasite fauna of the fishes was investigated twice-in summer and in autumn. It was found that in autumn it is much poorer than in summer. This concerns mainly the species with a complex developmental cycle.
