The paper studied the effect of feed bioadditives Levabon Rumen E and Digestarom P.E.P. 1000 and a complex of organic acids on the dynamics of mass accumulation, indices of visceral organs, anatomical pathological changes, and hematological parameters of juvenile trout. The maximum positive effect on the morphophysiological parameters and health of fish was revealed for yeast in combination with a phytobiotic as a feed bioadditive. The immune response was found to increase in fish fed bioadditives. A complex of organic acids adversely affects the state of the visceral organs and tissues of fish. A combined use of feed additives in the diet of juvenile trout is recommended in the following concentrations: 2% Levabon Rumen E and 1.5% Digestarom P.E.P. 1000. This combination helps to reduce intensive development of pathological processes in adult fish and improve the physiological parameters of juvenile trout.
