An equal mixture of soybean and horse gram flour was added to the - traditional carp diet (a mixture of 1:1 rice bran and oilcake in powder form) and fed to triplicate groups of common carp (Cyprinus carpio) fry at 10, 20, 30% inclusion levels. Traditional feed mixture without supplementation served as the control diet. All the diets were provided in pellet form to the fish reared in out door cement tanks for 90 days. The test diets significantly (P<0.05) improved fish growth. Survival of fish ranged from 80 to 87.5%. Net fish production was the highest with the 30% inclusion diet. Carcass protein and lipid levels were significantly higher in fish fed the test diets. Activity of digestive enzymes was also affected by the test diets.
