Size and weight of the pikeperch population Sander lucioperca (Linnaeus, 1758) of the Dagestan coast of the Caspian Sea

Abstract

The age, size, weight and sex structure of the population of pike perch foraging near the Dagestan coast of the Caspian Sea is shown. The significance of the studied sites for foraging migrations of pike perch is noted. he analysis of the biological indicators of the pike perch showed that the pike perch of the Tersk-Caspian region is an integral part of a single Volga population, going to spawn both in the rivers of the Dagestan coast (Terek river, Sulak river, etc.) and in the rivers flowing into the northern part of the Caspian Sea (Volga River, Ural River).
