<p>The analysis of the fi shery companies of the republic shows that the main drawback in the fi shing industry is the small volume of mass rearing of fi sh fry and the ineffective use of artifi cial groundwater reservoirs both – built in the 60-80s of the last century and those currently under construction. Due to the inappropriate size of the surface of these lakes, about 50-100 hectares, and insufficient depth in the ponds, small quantities of carp (2000-3000 units) are bred, large-scale repairs are being carried out, and the fish catchper pond with an area of 1.0 hectares is 1,0-3.0 tons, which, in turn, requires a large amount of water, mineral fertilizers and animal feed. The Innovative Fishery Center under the Fergana State University explores favorable hydrobiological conditions for intensivefi sh farming, with an account of the climate of the republic, without the use of aerators, by organizing the circulation of water in the pond water, in order to provide fi sh bred in the reservoir with a sufficient amount of oxygen, considering the insufficient surface of the area (0.5-1 hectares – ponds with artifi cial soil, up to 1.5 hectares – natural reservoirs). As a result of carp care in polyculture, fi sh productivity is increased by 3-4 times as compared to the method of extensive fi sh farming.</p>
