| Abstract | ||||
| Silver carp (H. molitrix) fingerlings with initial weight of 20.1 g. were stocked at a rate of 2500 , 5000 and 10000 fish/cage in 6 cages (two cages per treatment) each of 9 × 6 × 3 m. The total duration of experiment was 10 months (300 day). Wight gain and specific growth rate were significantly decreased with increasing stocking density. The highest net return was obtained with stocking density of 5000fish/cage, while the lowest net return was obtained with stocking density of 2500fish/cage. Survival was negatively correlated with stocking densities through the experimental period. In conclusion, the optimum stocking density of Silver carp under the conditions of this experiment is 5000 fish/cage in terms of growth performance, total production and net return. | ||||
