REVISITING DETERMINATION OF STOCKING DENSITY OF SILVER CARPS FOR STOCKING AND EFFECTIVE AMELIORATION OF WATER BODIES
At present, the rational use of water resources is very important. It is necessary to ensure their protection against pollution and degradation, and also skillfully restore them. Biological amelioration of water bodies is a method for improving the habitat of aquatic organisms and artificial enhancement of biological and economic productivity of bodies of water. The introduction into reservoirs of silver carps as biological ameliorator will not only effectively fight their overgrowing, improve their hydrochemical mode, but also obtain additional fish products. The results of the calculation of the required number of silver carps for stocking and effective reclamation of a water body under the conditions of the 4th zone of fish farming are presented. It is shown that to improve the condition of a water body with an area of 490 hectares, it is necessary to purchase 1720 silver carps with a minimum average mass of 100 g and a total ich-thyomass of 172 kg.
