Abstract
Aim. The aim of the research is to identify and characterize the current composition and state of the fish fauna of the Lake Bolshoe Toko. Methods. Age determination was conducted based on the annual rings on the scales, taken under the back fin above the lateral line; coefficient of fatness was determined on a six-point scale by Fulton and Clark, respectively. The rest of the material was also processed according to the generally accepted methods in ichthyology. Results. As a result of the research, for the first time was obtained updated data on age, height, sex ratio, spatial distribution of fish species in the lake, relative dominant species in this lake; some data on nutrition and helminth infection is also given in this article. Conclusions. Lake Bolshoe Toko is represented by fish of three faunal complexes, of which two species of fish are not typical representatives of the lake ichthyofauna; stuntedness and a high level of infection of the Siberian whitefish by helminthes is due to a high probability of overpopulation in the lake. Small and valuable breeds of fish that live in the lake need protection throughout the basin adjacent to the lake reservoirs.
