Morphophysiological Features of Rainbow Trout Oncorhynchus mykiss (Walbaum) Produced by Sex Reversal at the Third Year of Rearing

The characteristics of changes in liver, heart, spleen, gonadosomatic index, and body condition indices of trout in the third year of rearing under the influence of 17α-methyltestosterone (MT) are demonstrated. General rules regarding morphophysiological indices for females and redefined males are established.

Abstract

The characteristics of changes in liver, heart, spleen, gonadosomatic index, and body condition indices of trout in the third year of rearing under the influence of 17α-methyltestosterone (MT) are demonstrated. General rules regarding morphophysiological indices for females and redefined males are established.
