Abstract: Different growth and production parameters of cage cultured Vietnamese climbing perch(Anabas testudineus, Bloach), locally known as koi, were studied. Fishes were reared in bamboo framed netcages 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, wasinstalled with a total of nine 1m3 (1m x 1m x 1m) cages; wherein 100 fish m 3, 150 fish m 3and 200 fish m 3 wereset as the different stocking densities demarked as treatment T1, T2 and T3 respectively with three replicationseach. Mean initial length and weight of the fries were 4.21± 0.114, 4.42± 0.023 and 4.51± 0.047 cm for T1, T2 andT3, 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 T1, T2 and T3 recorded were 16.63± 0.119,16.12± 0.039, 16.67± 0.093 cmand 105.54±1.84, 118.60±2.535, 112.49±2.10 g, respectively. T2 showed the highestlength and weight gain after harvesting (P<0.05). The specific growth rate of T2 was found significantlydifferent among treatments and again T2 resulting the highest figure of 3.60±0.003 (%). The same treatment hadthe highest survival rate of 62.66 ± 4.66 (%) with a mean of 57.44±2.36 (%). However, no significant differenceamong treatments was observed for survival rate (P>0.05). Finally, the gross yield (kgm 3) was 7.929±0.92 inT2 (P<0.05) which was highest among all the treatments and T2 returned back lowest production of 3.39 ± 0.307kg m 3 which was significantly lower than the yield found in remaining treatments.The gross revenue earnedfrom selling of fish at a price of 220 Tk kg 1 were 747.98 ± 67.54, 1744.5 ± 203.6 and 1665.1 ± 187.7 Tk m 3 in T ,1T2 and T3, respectively. Whereasthe values,in terms of net profit, stood at 418.3 ± 141.16, 779.0 ± 170.73 and62.00 ± 43.40 Tk m 3 for the same treatments, respectively. Therefore, the cage with 150 fishes (T ) showed2promising growth, yield and survival rate which could be recommended to adopt. However, more trials aresuggested to optimize the stocking density and feeding regime for better production performance and profit
