Fundamentals of commodity fishery for the cultivation of silver carp in polyculture with carp in the conditions of the LLC “Kovcheg” of the Kyiv

Abstract

This scientific article describes the technology and stages of designing a fishery for growing silver carp in polyculture with carp in conditions of the LLC “Kovcheg” of the Kyiv. In the conditions of this economy the project of cultivation of fish in polyculture was developed, where calculations of average monthly temperature of ponds, content of dissolved oxygen in water were carried out, indicators of a source of water supply of ponds were analyzed, economic efficiency of cultivation of silver carp in polyculture with carp was carried out. Fish farms have a number of significant problems today, that prevent full and easy development – these are financial difficulties in the state, namely: disruption of economic ties, deterioration of the ecological condition of inland waters, insufficient work on the reproduction of fish stocks. In order to get fish farming out of the crisis, ensure sustainable development of the industry, strengthen the country's food independence, it is necessary first of all to solve issues related to environmental and economic problems of fisheries development, improving the economic mechanism of fisheries management, intensification of investment processes and innovations aquatic living resources. The fisheries sector includes the extraction, processing, reproduction and increase of stocks of fish and other aquatic organisms in natural and artificial reservoirs. It provides valuable food, feed, medicine and technical products. Fisheries are aimed at preserving and improving fish stocks in natural reservoirs and breeding fish in artificial reservoirs. In order to ensure food security of Ukraine, it is necessary to work on the following areas: scientific substantiation of the raw material base and rational fishing, protection of aquatic ecosystems, technology of processing of aquatic fish resources.
