The question of the effectiveness of domestic extruded compound feed in feeding carp fish was studied - as one of the methods of complex intensification of commercial fish production technology in the conditions of an individual fishery. The importance of studying this issue is dictated by the harsh realities of today, which are caused by the global trends of growing deficits in food products, among which a large share is occupied by fish and fishery products. The increase in demand for high-quality agricultural products and their prices is due to the crisis phenomena in the world economy, caused to some extent by long-term quarantine restrictions on all continents of the planet and the war in Ukraine. The purpose of the work was to study the technological processes of feeding in the cultivation of commercial carp and search for optimal methods for their improvement. To achieve this goal, the following tasks were performed: chemical and hydrobiological parameters in pond water were investigated; linear growth rate, weight growth rate, and carp fattening rate were analyzed; the fishery and economic indicators of the farm “Mykolaivska RMS” were analyzed. In two experimental ponds of the farm, they studied the peculiarities of growing carp fish when feeding them with domestic granulated compound feed with an optimal ratio of nutrients and biologically active substances while systematically determining the hydrochemical and temperature regimes of the experimental ponds, studying the morphometric indicators of two-year-old carp, calculating the fish productivity of the ponds of the farm and economic efficiency use of Reucher Aqua “Carp” feed. The obtained results confirm the effectiveness of using dry water-resistant extruded feed for feeding carp fish, which is manufactured according to modern technologies: it does not decompose in water for a long time. Therefore it does not change its quality and color; balanced in terms of the primary nutrients and biologically active substances, which positively affects the growth and development of fish, quality, and taste indicators of their meat. The use of this feed in a complex of intensification measures to improve technological processes in fish farming will allow obtaining a significant production and economic effect.
