A study was conducted to establish and optimal methods under twofeeding regime (poultry waste and supplimental) for the culture of Indian major carps by comparing the growth patterns and to develop a cost efficient feed and feeding technique through cost benefit analysis for future use in Bangladesh. Static 5.00 mg/L dissolved oxygen content was the remarkable observation during the investigation period in both study ponds except March‟14 at treatment I and treatment II. The ponds were slightly alkaline with pH values ranged from 6-7 Hardness, alkalinity and ammonia showed narrow difference in their mean value. All of the water variables showed significant deference (P<0.05) excepting water temperature. The ten months investigation showed the average final weights (gm) of Labeo rohita, Catla catla, and Cirrhinus mrigala were 700±2.89 , 900±0.78, 700±1.55 at treatment-I and 170± 2.23, 235± 1.22 165±0.45 at treatment II respectively. Monthly mean weight gain (gm.) of the species were 1.23±0.79 , 1.23±0.75, 0.92±0.67 at treatment I and 0.64±0.43, 0.64±0.56 and 0.50±0.47 at treatment II respectively and specific growth rate (%) of rohu, catla, and mrigal were 0.87%, 0.87% and 0.89% at treatment I and 0.40 and 0.39% at treatment II respectively. Weight gain pattern was same for both the treatments. Catla catla was the fastest growing species among species under investigation. Food conversation ratio was the lowest (0.034) in Catla catla which indicate better conversion of food into flash and followed by Labeo rohita and Cirrhinus mrigala (0.045) at treatment I. At treatment II, the calculated food conversion ratio showed highest value in Cirrhinus mrigala (5.74) followed by Labeo rohita (5.20) and Catla catla (3.67) indicated poor growth performance of species under investigation. CB indicate higher profit (53591Tk) at treatment I. The level of input given to the treatment produced 690kg at treatment I and 170kg at treatment II. Which were much higher than the break-even production level (120.24kg and 113.36 kg), the two feeding regimes are economically viable. It was also observed that there were many possibilities to increase production further by introducing and adopting better management practices
