Cultivated hydrobionts under intensive aquaculture conditions are exposed to stress factors associated with artificial habitats, increased planting density, periodic fishing, etc. At the same time, they experience a decrease in resistance and resilience and an increase in morbidity. A good solution to this problem is the use of immunomodulators. This article presents the results of a study of the effect on fish of the immunomodulator Roncoleukin, which is a dosage form of recombinant human interleukin-2 (IL-2) isolated and purified from yeast cells (Saccharomyces cerevisiae). The subject of the study was the three-year-old Arctic char (Salvelinus alpinus). The evaluation was based on morphometric, hematological (erythro- and leukogram) and cytochemical (lysosomal cation test) indicators. The coefficient of variation of the size and weight parameters of the treated fish was low compared to the con- trol group. This indicates uniform growth of fish fed Roncoleukin, which is a great advantage in fish farming and provides more efficient use of feed. Blood for analysis was taken from the tail vein of the fish in vivo. The results showed a positive effect of the drug on the activation of erythropoiesis and leukopoiesis. There was a significant increase in the proportion of mature segmented neutrophils (the main blood microphages belonging to the non-specific link of cellular immunity) in the leukocyte formula due to a decrease in lymphocytes (specific immunity). An increase in the content of nonenzymatic lysosomal cationic proteins (defensins) in blood neutrophils can indicate a high level of cellular protection of microphages (neutrophils). The results of the study showed a positive effect of the drug Roncoleukin, which can be recommended for use in the ferming of Arctic char.
