Additional addition of carp to the diet in the ratio: Spirulina Platensis - 40%, Chlorella vulgaris - 30% and Artemia salina - 30% made an impact on the parameters of carp development. The components were cultured in a bioreactor built into a recirculating aquaculture system. The results showed that after additional feeding of carp with the indicated components, the body weight of one-year carp was higher than the control group by 8.9%, and safety by 3.4%. Body weight two-year carp was greater in the experimental group than in the group where the fish ate the total diet. The difference was 12.1% in body weight and 2.9% in safety. These parameters were significantly lower in fish fed the control diet (P<0.05). This scientific work has demonstrated the additional use of natural food as a method for improving the blood composition of carp: an increase in hemoglobin by 15.5% (P<0.05), erythrocytes by 5.5% in comparison with the control group. Indicators of gas-discharge visualization of a biological object supplemented the obtained result. Keywords : Carp, Food factor, Natural feed, Growth, Physiological processes
