Abstract :The current study\`s goal was to look at how stocking densities affected Bheda insert ignore into journalissuearticles values(Nandus nandus); growth and production over the course of a 120-day period. Three treatments were T1 insert ignore into journalissuearticles values(20,000 fish ha-1);, T2 insert ignore into journalissuearticles values(30,000 fish ha-1);, and T3 insert ignore into journalissuearticles values(40,000 fish ha-1);, each with three replicates. Those fishes were fed daily with commercial sinking feed and a live food mixture at 9-3% fish body weight up to harvest-ing. Temperature, dissolved oxygen, pH, and other water quality indicators were measured every two weeks, along with the growth performance of Bheda fish. T2 had the highest yield of Bheda insert ignore into journalissuearticles values(3439.08±207.31 kg ha-1);, followed by T3 insert ignore into journalissuearticles values(3422.78±224.42 kg ha-1);, and T1 insert ignore into journalissuearticles values(3136.62±150.00 kg ha-1);. The harvesting weight insert ignore into journalissuearticles values(g);, individual weight gain insert ignore into journalissuearticles values(g);, individual percent insert ignore into journalissuearticles values(%); weight gain insert ignore into journalissuearticles values(g);, SGR insert ignore into journalissuearticles values(% per day);, and survival rate insert ignore into journalissuearticles values(%); of fish were significantly higher insert ignore into journalissuearticles values(p<0.05); in T1, followed by T2 and T3, respectively, where combined production of fishes was significantly higher at T2 followed by T3 and T1. Net profit and benefit-cost ratio were significantly higher in T1 than T2 and T3. Based on the re-sults of this experiment, it can be concluded that stocking density of Bheda fingerlings at the rate of 20,000 fish ha-1 in T1 showed the highest production performance for profitable pond aquacul-ture. However, further research on the standardisation of stocking density with economic profitabil-ity of this fish at the on-station or on-farm level in ponds may be required before widespread dis-semination of this culture technology to farmers, particularly in Bangladesh and elsewhere.
