Abstract: A study was conducted to compare the growth, survival and production performance of Genetically Male Tilapia (GMT) derived from YY male, Sex Reversed Tilapia (SRT) produced through the masculinization of sexually undifferentiated fry with 17-α-methyltestosterone and Mixed Sex Tilapia (MST) in six earthen ponds with a stocking density of 100 fish/decimal. Fishes were fed with supplementary feed containing approximately 30% crude protein. The initial weight of GMT, SRT and MST was 5.45±0.35, 4.35±0.35 and 4.70±0.50 g, respectively. Over the culture period of 105 days, the weights of GMT, SRT and MST were found 193.21±3.07, 176.36±0.94 and 154.82±2.57 g respectively and the performances were significantly different (P<0.05) from each other. The survival rate of GMT, SRT and MST was 91.68±1.35%, 87.38±1.38% and 88.16±0.73% respectively and they were not significantly different (P>0.05). The net production of GMT (4252.77±124.06 kg/ha) was significantly (P<0.05) higher than that of SRT (3712.56±71.46 kg/ha) and MST (3269.40±72.01 kg/ha).
