The object of the research was amber trout. The growth, development of fish, and the morphological composition of fish were studied. Gross weight gain of trout when fed with additives containing glycerin and milt increased by 12.7 - 18.2%. The condition factor of trout in the control was 1.74. In the groups receiving feed additives, the coefficient of fatness exceeded that of the control group; in group 2, the difference was significant and amounted to 5.2%. There was a decrease in the feed ratio when using feed additives by 0.7 - 4.0%, compared to the control. The weight of the gutted carcass in all groups ranges from 77.6 to 79.7%. No pathologies were found in the internal organs of fish in all groups. In the experimental groups, bone tissue mass was greater than in the control group, in groups 2 and 3 at P<0.05, in groups 4 at P<0.01. The weight of muscle tissue in all experimental groups exceeded the control, in groups 2, 3 and 4 with significant differences at P <0.05.
