Fishes were reared in bamboo framed net cages under three different stocking densitiesina single experimental culture cycle of 4 months (July to October, 2013). The experimental earthen pond at Sher-e-Bangla Agricultural University (SAU) campus, Dhaka, was installed with a total of nine lm~(-3)(Imx Imx Im) cages; wherein 100fishm~(-3) 150 fish m~(-3)and 200 fish m~(-3) were set as the different stocking densities demarked as treatment Ti, Tj and T3 respectively with three replications each. Mean initial length and weight of the fiies were 4.21± 0.114, 4.42± 0.023 and 4.51± 0.047 cm for T_2 Tj andTj, respectively. Mean initial weight for the same treatments were 1.62 ± 0.089, 1.54 ± 0.045 and 1.60 ± 0.0097 g, respectively. Whereas the mean harvesting length and weight for T_1, T_2 and T_3 recorded were 16.63± 0.119, 16.12±0.039,16.67± 0.093cm and 105.54±1.84,118.60±2.535,112.49±2.10 g, respectively. Tj showed the highest length and weight gain after harvesting (P<0.05). The specific growth rate of T^ was found significantiy different among treatments and again Tj resuhing the highest figure of 3.60±0.003 (%). The same treatment had the highest survival rate of 62.66 ± 4.66 (%) with a mean of 57.44±2.36 (%). However, no significant difference among treatments was observed for survival rate (P>0.05). Finally, the gross yield (kgm~(-3)) was 7.929±0.92 in T2 (P<0.05) which was highest among all the treatments and Tj returned back lowest production of 3.39 ± 0.307 kg which was significantly lower than the yield found in remaining treatments.The gross revenue eamed from selling offishat aprice of220 Tk kg~(-1)were 747.98 ± 67.54,1744.5 ± 203.6 and 1665.1 ± 187.7 Tk m~(-3) in T_1, T _2and T_3, respectively. Whereasthe values,in terms of net profit, stood at 418.3 ± 141.16, 779.0 ± 170.73 and 62.00 ± 43.40 Tk m~(-3) for the sametreatments, respectively. Therefore, the cage with 150 fishes (T_2) showed promising growth, yield and survival rate which could be recommended to adopt. However, more trials are suggested to optimize the stocking density and feeding regime for better production performance and profit. 收起
