Evaluation of Linear Growth Indicators of River Perch (Perca Fluviatilis L.) in the Kuibyshev Reservoir

Abstract

This article analyzes the rate of linear growth of river perch from different ples of the Kuibyshev reservoir, and considers the possibility of identifying ecological forms of this species based on data on the growth rate. The dependence between the growth rate of fish and the hydrological characteristics of the studied areas of the reservoir is revealed. The linear growth rate of male and female river perch was compared, and sexual differences in growth were found. The rate of linear growth of perch in modern conditions of the Kuibyshev reservoir is compared with the results of other researchers.
