Four treatments were considered having two replicates. For supermale tilapia treatments were named as ST<sub>1<\/sub> and ST<sub>2<\/sub> and for monosex tilapia were MT<sub>1<\/sub> and MT<sub>2<\/sub>. All the fish were of same age group having mean body weight of 1.4 g. Feeding frequency in all the treatments were two times a day. Fish were fed diet at a rate of 30% of their body weight for the first thirty days that was gradually reduced to 15% for the next thirty days and 5% till the termination of the experiment. Final weight, weight gain, average daily weight gain, % weight gain and production of supermale tilapia were significantly (p&lt;0.05) higher than those of monosex tilapia. But SGR (% day), FCR and survival rate of supermale tilapia were not significantly (p&gt;0.05) varied. However, the result of the present study showed that the best weight gain of 124.85 g was observed in ST<sub>1<\/sub> after 90 days culture period. Average weight gain (g) were 1.39, 1.16, 1.14 and 1.05, SGR (per day) were 2.17, 2.09, 2.08 and 2.04%, FCR were 2.98, 2.65, 2.84 and 2.57, survival rate were 96, 94.50, 95 and 91% and fish production were 5053.92, 8926.10, 4108.07 and 7821.41 kg\/ha in ST<sub>1<\/sub>, ST<sub>2<\/sub>, MT<sub>1<\/sub> and MT<sub>2<\/sub> respectively. The present research findings suggested that supermale tilapia has significantly high growth potential compare to monosex tilapia under mini ponds culture condition.<\/p>\n<p style=\"text-align: justify;\"><strong>Key words: <\/strong>Growth;
