Abstract: First growing strain of climbing perch Vietnamese koi (Anabas testudineus) seed was imported from Vietnam at 2012. Presently, this strain is getting more popularity than our native and Thai koi strain as the growth rate of Vietnamese koi is much higher. An experiment was conducted from 6 May to 6 September 2013 to optimize the stocking density of Vietnamese climbing perch in the cage at Patuakhali district. Nine cages were used for this experiment having size 2.5m × 1.8m ×1.3m. The experiment was designed into three treatments having three replications assigned into a completely randomized design with various stocking density. The stocking density of different treatments T1, T2 and T3 were 50, 75 and 100 fry.m-3, respectively. Mega floating koi feed was delivered at a rate of 3 to 10% body weight twice a day. There was no significance difference among treatments for different yield parameters of Vietnamese koi (p<0.05). Survival of fish was not significantly affected by the stocking density and ranged between 93.33 to 95.66%. The significantly (p<0.05) higher fish production (kg.m-3) was found in T3 (13.32 kg) compared to other treatments. A simple economic analysis of the Vietnamese koi cage culture showed that T3 generated the maximum net profit Tk. 1052.02 m-3 in four month followed by T2 (Tk. 793.96) and T1 (Tk. 532.65). So the present study revealed that highest stocking density (100 m-3) of Vietnamese koi is most suitable in terms of production and economics in cage culture.
