ALIEN FISH SPECIES IN COOLING RESERVOIRS OF NUCLEAR POWER PLANTS AND STATE DISTRICT POWER STATIONS OF CENTRAL RUSSIA

Abstract

The article presents an overview of alien fish species living in cooling reservoirs of nuclear power plants and state district power stations in Central Russia. A brief description of recipient reservoirs is given as a habitat for thermophilic fish species that are not characteristic of the native ichthyofauna of the region. The essays on the history of the appearance of these species, the peculiarities of biology, occurrence in catches, and fishery significance in six small reservoirs of special water management located within the borders of the Moscow, Smolensk, Ryazan and Kursk regions of Russia are given. The main vectors of invasions of hydrobionts in cooling reservoirs for each alien species recorded as a result of ichthyological monitoring in this group of reservoirs are shown. The forecast of the dynamics of the number of alien fish species is given depending on changes in the thermal regime of reservoirs, the volume of stocking and the intensity of fishing in the cooling reservoirs of nuclear power plants and power plants of Central Russia.
