The aim of the work was to study red and white blood composition of African sharptooth catfish, reared with application of innovative biotechnology elements, which involve usage of a complex of biologically active components, including Irkutin adaptogen, Sporothermin probiotics and Chiktonik vitamin and amino acid complex. Irkutin adaptogen was used to increase fish organism resistance to unfavorable environmental factors. Sporothermin probiotics was applied as an immunomodulatory agent to increase immunity, reduce the negative effects of stress factors, prevent infections, and regulate microbiocenosis. Chiktonik vitamin - amino acid complex was considered as a source of vitamins and amino acids, which the fish organism desperately needs when reared in recirculating aquaculture system. The object of the study was sexually mature males and females of African sharptooth catfish. The tasks of the work included assessment of the fish blood system reaction to components of our functional feed additive. The results of the research showed that application of Irkutin adaptogen in rearing of African catfish had an activating effect on the level of erythrocytes, leukocytes and hemoglobin content in the fish blood. Usage of Sporothermin probiotics also had a conspicuous effect on the content of blood corpuscles and hemoglobin content. However, Chiktonik vitamin-amino acid complex had the strongest activating effect on blood parameters, all parameters were significantly higher than in case of application of other biologically active components. The activating effect of each biologically active component did not go beyond the physiological norm.
