Aim: To evaluate the effects of 17α-methyltestosterone treatments on growth performance, morphological and biochemical blood parameters, condition of internal organs, and sex reversal in juvenile rainbow trout. Methods: Experiments were conducted on larvae and juveniles that received feed supplemented with 17α-methyltestosterone for 3, 4, and 8 weeks after the onset of exogenous feeding. The influence of the hormone was assessed based on hematological and biochemical blood indicators, as well as
