Problems and perspectives of using warm waters of the state district power station in solving the provision of the population with fish

Abstract

One of the sources of increasing fish production in Russia is intensive fisheries development of cooling reservoirs of thermal power plants and nuclear power plants. Cooling reservoirs have a unique temperature regime, which differs from natural water bodies by a higher temperature throughout the year. The increased water temperature causes changes in the quantitative and qualitative composition of the forage reserve, the ichthyofauna, the habitat of the hydrobiont and creates favorable opportunities for the introduction of a complex of thermophilic fishes and enhance the fish productivity of water bodies. The rise in water temperature also accelerates chemical and biochemical processes, promotes the intensive decomposition of organic substances, influences the gas regime of the reservoir, as a result, there may be overseas phenomena and the death of fish in cooling reservoirs. Therefore, the growing of aquaculture objects, the most resistant to high temperatures and temperature and gas changes, is becoming topical.
