Hematological parameters of fish after applying biologically active feed additive

Conducted research work on the evaluation of the effectiveness of juvenile sturgeon of the Lena nutrient feed additives. The use of feed additives in the feed mixture for growing fish enables you to strengthen the growth and improve the physiological state of the cultivation by enhancing resistance to different environmental factors. The authors conducted research to study the effects of feed additives on hematological parameters of Lensky sturgeon and some fish characteristics. The experiment was performed on two groups of fish (control and experimental). The experimental group received a biologically active food additive Akwa-Biot-Norm in the composition of feed and the control feed only. According to the results of the experiments the positive effect of feed additives on the growth and survival of fish while simultaneously improving the overall physiological condition (based on the results of hematological analysis). So, the addition of feed additives has increased the number of erythrocytes and leukocytes, hemoglobin and total protein in blood plasma. The increase in the number of common protein in the blood serum of the Lena sturgeon on a background of application of nutrient feed additives indicates activation of synthetic processes in the fish organism, as a consequence, increase the intensity of the fish growth. Therefore, feed additive Akwa-Biot-Norm stimulates the immune system of fish and can be used for their cultivation.
