The experiment was carried out for 94 days in the renowned Ratargul Freshwater Swamp Forest of Bangladesh in order to assess the production performance and economics among three locally high-demand catfish species with a view to selecting suitable species for cage culture. Magur (Clarias batrachus), pabda (Ompok pabda) and pangas (Pangasianodon hypophthalmus) were stocked in Treatment-1 (T 1 ), Treatment-2 (T 2 ) and Treatment-3 (T 3 ), respectively at stocking densities of 40 fish/m 3 , 60 fish/m 3 and 40 fish/m 3 , respectively with three replications each. The mean initial weights of fish were 25.35±0.55 g in T 1 , 15.45±0.30 g in T 2 , and 18.16±0.55 g in T 3 . Fishes were supplied with commercial floating starter feed at the rates of 10-5% live body weight of fish for the first month, and grow-out feed at the rate of 4% body weight from the second month to till the end of the experiment. Species were sampled monthly. Results show that the average individual harvesting weight of fish was 141.93±9.86 g in T 1 , 53.22±3.07 g in T 2 and 363.75±12.09 g in T 3 at the end of the experiment which was significantly different among the treatments. Total yield was found significantly higher in pangas (13.20±0.69 kg/m 3 ) than magur (3.71±0.14 kg/m 3 ) and pabda (2.86±0.27 kg/m 3 ). Though there were no significant differences among the benefit-cost ratios for all the treatments, the highest was accounted for T 3 (1.25±0.08), followed by T 1 (1.22±0.05) and T 2 (1.19±0.11). The findings of the present experiment suggest that pangas could be a suitable species followed by magur and pabda for cage farming in freshwater swamps.
