【 摘 要 】

A complex ecological situation develops in the area of the largest reservoir of the Volga cascade - Kuibyshev, especially in the areas of concentration of population and production. In connection with the development of aquaculture, the problems of conservation and reproduction of sterlet in the Kuibyshev reservoir become actual. Taking into account the tasks of preserving water quality in the upper part of the Volga reach of the Kuibyshev Reservoir as a spawning site of sturgeon in the early 20th century, special attention was paid to the impact of waste water discharges from the Mari Pulp and Paper Mill (JSC "MTSBK"). The hydrochemical and hydrobiological characteristics of section of the Volga reach of the Kuibyshev reservoir and secondary settler of JSC "MTSBK" were studied. The change in the qualitative and quantitative characteristics of the hydrobiocenosis in the conditions of functioning water treatment plant was shown.
