Results of introduction of new fish species into Lake Munozero (southern Karelia).

Abstract

Fish culture works on introducing valuable fish species into Lake Munozero (southern Karolina) are analyzed. It is shown that the introduction of two species, bream and char, led to the formation of self-reproducing populations in the lake. Whitefish has not been naturalized in the lake, which is possibly due to the absence of areas and conditions for reproduction, as well as to its grazing by predators (pike, burbot, and perch) and large catches during spawning. The biological indices of aboriginal and introduced fish species are presented.
