Effect of 17 Aplha Methyl Testosterone on Sex Reversal of Oreochromis Niloticus Fry
The effect of oral application of three concentrations of 17 α methyl testosterone (17 α-MT) in sex reversal of Oreochromis niloticus fry was studied. About 1,200 day one O. niloticus larvae with an average weight of 0.002g distributed into 12 plastic container (each 14L capacity). The experiment consisted of four treatments and three replicates for 17 α-MT application in stage one, and 12 happa (1m×1m×1m) in stage two for fry rearing. The male% increased significantly (p<0.05) with increase of 17 α-MT concentration. T1 (63%) yielded 84%; T2 (78.3%) yielded 87% and T3 (86.7%) yielded (89%). Survival rates significantly decreased (p<0.05) with the increase of 17 α-MT level (T3, T2 and T1, respectively). The proved that oral application of 17 α-MT is useful in sex reversal and production of male of O. niloticus.
