IMF = immature females; IMM = immature males; MM-1/-2 = maturing males (1: GSI<5 and 2: GSI>5); VSI = viceralsomatic index; HSI = Hepatosomatic index; GSI = Gonadosomatic index. Mean±SE. Statistical analysis by 2-way ANOVA, mean effect of maturation status (M; immature vs maturing) and gender (G; females vs males), followed by Tukey post hoc test were different letters denote significant differences (P<0.05) among groups.
