- A 60 days experiment was carried out under laboratory conditions where Cirrhinus mrigala, mrigal fries (0.55±1g) were maintained in glass aquaria filled with fresh water. Three main protein sources fish meal (protein from animal source), sesame oil cake and soybean meal (protein from plant source) were used in diets. Further, soybean was taken in two forms raw and processed. Eight diets were formulated with equal proportion of raw soybean in 1-4 diets, and hydrothermically processed soybean in 5-8 diets following inclusion levels (65, 130, 195, 260 g kg-1 diet). While sesame oil cake was incorporated in all diets in equal amount. 100% fish meal based diet was used as control in this experiment. Fishes were randomly distributed @ 15 fish per aquarium with duplicates for each dietary treatment. Results showed that where mrigala fry fed on processed soybean based diet Growth % gain and SGR % significantly (P < 0.02) increased. Protein efficiency ratio recorded maximum in diet 5. Maximum values were increase in these parameters were observed in diet 6th, where fish meal and processed soybean meal were applied in equal amount in diet in comparison to fish fed on control diet. Feed intake was also declined with the increase in inclusion level of soybean meal, but the feed conversion ratio (FCR) and protein efficiency ratio (PER) maximum in diet 3 and reference were followed by other diets. Our results suggest that soybean meal can be a suitable source without compromising weight gain or feed efficiency in fry of C. mrigala
