Purpose. Assessment of the economic efficiency for growing 0+ bester under conditions of increased heat load with the introduction of the probiotic “Subalin” into their diet.

Methodology. Economic calculations were carried out according to generally accepted methods using production costs, cost price and product price, and production profitability. To determine and analyse the economic efficiency of technological processes for growing bester juvenile of age group 0+, the actual results of the production activities of the industrial-type farm “Biosyla” LLC were used. Experimental and control groups of sturgeon hybrids were formed, which were grown in tanks using heated waste water from a power plant. The average weight of 0+ bester at the beginning of the growing period was 22.77 and 70.53 g. The fish were fed with commercial compound feeds of recommended formulas with the additional introduction of the probiotic preparation “Subalin” into their diet at an amount of 0.03–0.04% of the weight of the main feed.

Findings. Productive and economic benefits have been established based on the results of introducing the probiotic “Subalin” into the diet of 0+ bester. As a result of cultivation for 50–65 days at a water temperature of 27.5–33.7°C, the experimental groups of fish reached an average weight of 195.44–259.52 g with a survival rate of 100%. During experimental feeding, an increase in the total weight of grown products by 18.12–25.57% was noted. At the same time, the consumption of basic feed for fish weight gain decreased by 8.51–16.33%. The share of costs for the purchase of “Subalin” in the cost of sturgeon juvenile production did not exceed 0.02%. With the use of “Subalin”, the profitability of growing a sturgeon hybrid increased to 42.55–65.47%, which was more than twice those in the control.

Originality. For the first time, the economic efficiency of growing bester from age group 0+ with the introduction of the probiotic drug “Subalin” into the fish diet has been analysed, which contributes to the development of the scientific foundations of modern sturgeon aquaculture in Ukraine.

Practical Value. The results obtained are of interest for assessing the economic efficiency of growing sturgeon juvenile in industrial-type farms, in particular in the process of improving methods of feeding sturgeon fish under conditions of increased thermal load on the environment of fish ponds.

Keywords: economic efficiency, growing sturgeon fry, bester, tanks, feeding, probiotic “Subalin”, water temperature.
