An evaluation of the comparative growth performance of sex reversed male tilapia (SRT) and genetically male tilapia (GMT) of two strains of Nile tilapia Oreochromis niloticus was carried out in triplicate cages immersed in an 800 m<sup>2</sup> fertilized pond over a period of 196 days. SRT of a Thai strain (EA–SRT), SRT of a strain introduced from the Philippines (ES–SRT) and an inter-strain SRT of the two strains (EA×ES–SRT) were produced by oral administration of 17 α-methyltestosterone. GMT of the Philippine strain (ES–GMT) and inter-strain GMT (EA×ES–GMT) were derived from crosses between novel YY-males of the Philippine strain with normal females (XX) of Philippine and Thai strains, respectively. Significant differences in mean body weights between treatments were observed at final harvest, EA–SRT and EA×ES–SRT having grown significantly larger (P
