Abstract

This article presents the results of using the sorbed probiotic preparation “Ecoflor” when growing hybrid forms of sturgeon fish. It was established that when using a probiotic-enterosorbent, the peripheral blood of the Russian-Lena sturgeon was lymphoid in nature. The level of lymphocytes in the blood of fish from the experimental groups increased to 78.50%, the proportion of band neutrophils increased to 8.80%, and segmented neutrophils – to 4.66%. It should be noted that the use of the probiotic contributed to a decrease in eosinophils (1.15%) and blast cells (4.50%). The leukocyte shift index in the blood of fish from the experimental groups did not exceed 0.32 and was within the reference values.
