“…Fish body length and mass, sex, gonad maturity stage, fecundity and feeding were analyzed. The samples were analyzed in the laboratory using generally accepted methods [8]. The age of fish was estimated from its scales and otoliths.…”

The composition of the fish population of three water bodies in the Kenti River system (White Sea basin), polluted by waste from a mining concentration plant, was analyzed. Only four out of 12 fish species of the Kenti River system (pike, burbot, bleak and roach) occur in all the water bodies studied. The fish population is dominated by roach. Smelt and dace were shown to be most sensitive to industrial waste. The closer to the source of pollution, the smaller the number of fish species in the lake. The impoverishment of the fish fauna is largely due to its (alkaline) habitat and the loss of spawning and growing conditions for juveniles (small areas occupied by aquatic vegetation).

The feeding of perch (Perca fluviatilis) from the littoral zone of Ladoga Lake was studied. Attention was focused on the colonizer species, a Baikal amphipod (Gmelinoides fasciatus), and its contribution to feeding. The invasion of Ladoga Lake by the Baikal amphipod has provided a new food item accessible to the fish. The results of the study have shown that the habitat of perch is largely the same as that of the Baikal amphipod. The food of perch was found to consist of various bottom fauna representatives. The colonizer Baikal amphipod made up over 40% of the food bolus by weight, indicating its great contribution to perch’s feeding.
