M.M. Rahman, M.J. Islam and S.M. Rafiquzzaman    

Abstract: Genetically Improved Farmed Tilapia (GIFT) is one of the most successful one of all exotic fish species in Bangladesh from the view of acceptance and prevalence in cultured water bodies. Manual separation of male and female tilapia is one of the methods for obtaining single sex. In Bangladesh, abundance of sex reversed GIFT male is very limited, therefore, the experiment was conducted to compare the yield of manually separated GIFT with others. Highest yield (5285.3±289.9 kg ha-1) and gross return (358343.7±23555.6 tk ha-1) were found from manually separated male GIFT, which was significantly different from others. Even manually separated female GIFT gave the better production than culture of both sexes together and of carps also.
