This study was conducted to compare the growth, sex ratio and fillet characteristics of genatic male tilapia (GMT), new hybrid tilapia (NH) and commercially tilapia (GIFT strain), respectively. The heaviest body weight and highest daily weight were found in the GIFT group, while the specific growth rate of the GMT group was higher than others through out the experimented period. Survival of the NH group (87.0%) was lower than the groups of GIFT and GMT. However, the better feed conversion rate was found in the NH group than other groups. The fish of GIFT group ingested more feed, consequently the feed cost nereased. On the other hand, the feed cost per kg weight gain was the lowest in the NH group. The sex ratio of the NH group (99.5%) was higher than thatof the GIFT group (81.0%). The results of texture test in dieated that the highest hardness and chewiss was observed at fillet of the GIFT group, meanwhile the shearforce of the NH groug was higher than that of the other groups. The crude fat of the fillet of NH group significantly higher than that of the GIFT group, in contrast, higher moisture was found in the GIFTT group. Regarding the fillet yield, the NH gruop was significantly higher than the groups of GMT or GIFT.
