Partial replacement of fishmeal protein by soybean meal protein in the diet of mrigal, Cirrhinus cirrhosus (Ham.) fry
To find out a suitable balance diet for Cirrhinus. cirrhosus fry substituting fish meal protein by full-fat soybean meal protein as dietary protein source for C. cirrhosus fry (1.29g) was studied in 12 aquaria for 60 days. The fishes were fed with four iso-nitrogenous(30% protein) and iso-caloric experimental diets viz. diet 1 (100% fish meal protein), diet 2 (75% fishmeal protein and 25% soybean meal protein), diet 3 (50%fishmeal protein and 50% soybean meal protein) and diet 4 (25% fish meal protein and 75% soybean meal protein). Among the diets the best growth, FCR and PER wereobtained with diet 3 fed fishes and no significant difference (p<0.05) was observed between diet 1 and 2 and diet 4 offered the worst performance. Therefore, considering fish growth, FCR and PER, it can be suggested that fish meal protein might be replaced 50% by soybean meal protein in the diet of C. cirrhosus fry for better growth.
