The fish population of small water bodies in Lake Onego catchment, and their prospective uses
The results of the surveys of two small lakes located in the western and southern parts of the Republic of Karelia (Sukkozero and Kedrozero) are reported. Hydrological and hydrochemical indices were analyzed. The water bodies are of glacial genesis, and belong to the catchment of Lake Onego. Human p...

The results of the surveys of two small lakes located in the western and southern parts of the Republic of Karelia (Sukkozero and Kedrozero) are reported. Hydrological and hydrochemical indices were analyzed. The water bodies are of glacial genesis, and belong to the catchment of Lake Onego. Human population in the catchments of the lakes is scarce, there are no large industrial enterprises, fish farms, etc. The lakes are classified as β-oligotrophic on the trophicity scale. Some bays and sites of Lake Kedrozero have acquired mesotrophic traits. Hydrobiological data, including the fish population of the lakes, are presented in detail for the first time. The fish species composition, length-weight growth and diet of the prevalent species were studied. The fish population of Lake Sukkozero is represented by 10 species, of Lake Kedrozero – by 14 species. Smelt, perch, roach and bream are the most abundant in both lakes.
