The author determined the correlations in the growth of bream, pike perch, roach, whitefish and small whitefish - Coregonus albula coexisting in lakes. Negative correlations of growth are noted for species of various thermal requirements. The pairs of species playing a similar role in ichthyofauna assemblages of overlapping feeding niches, living in various types of lakes as well as the fish of various sizes demonstrated separate types of growth correlation. The pairs of species forming the relation of “predator-prey” demonstrated special correlations of growth.
