The article presents the results of the use of humic acids in the cultivation of Lena sturgeon in closed water supply installations. The use of "Reasil ® Humic Health" at a concentration of 1.5 g per 1.0 kg of mixed feed in fish feeding contributed to an increase in the productivity of Lena sturgeon by 6 %. Humic acids have a wide range of biological activity, affecting the metabolic processes in the body of animals and humans. The introduction of humic acids into the diet of sturgeon helps to increase productivity, due to the ability to stimulate the production of enzymes, reduces feed costs by 1 kg of growth. The use of Reasil ® Humic Health feed additive based on unmodified microporous humic acids from Leonardite in the diet of sturgeon contributes to an increase in profitability by 9.4 %.
