THE CURRENT STATE OF THE DEVELOPMENT OF THE FISHERIES OF THE KAPSHAGAI RESERVOIR AND THE INFLUENCE OF THE MAIN FACTORS ON THE FORMATION OF ITS BIORESOURCES

Abstract

This article presents a voluminous holistic material prepared on the basis of the analysis of the monitoring studies carried out since the beginning of the filling of the Kapshagai reservoir, the largest reservoir created in 1970 in the south of the republic, on the middle course of the transboundary Ile River. The main issues of discussion are the complex of the main factors that had a direct impact on the formation of the 15 biological resources of the reservoir. Among them, the ecological conditions of the habitat of hydrobionts (hydrological, hydrochemical and hydrobiological regimes), the results of the work performed on stocking and acclimatization, as well as the conditions of natural reproduction of fish resources, anthropogenic impact on fish resources (commercial and amateur sports fishing) and the state of protection of fish resources are highlighted. This article is written within the framework of the Natural Resources program "Comprehensive assessment of the state of fish resources and other aquatic organisms of the main fishing reservoirs of Kazakhstan and the development of scientifically based recommendations for their sustainable use".
