The spawning efficacy of the above groups after 72 h were recorded indifferent instances as: spawning response 50-55%, fecundity 2,000-3,000 eggs/female (30 g aprox.) and fertilization range 80-85% over non-spawn response ofcontrol groups within those hours. The non-induced males of experimental groupsproduced 45.6 ± 9.41 pi milt over 10.2 ± 2.46 pi of the control group at 12 h, whichis highly significant
