AbstractSilage prepared by acid digestion of wastes from fish market and co-dried with rice bran was used as ingredient in experimental diet for rohu ( Labeo rohita ) fingerlings as source of animal protein by partial or complete replacement of fish meal. Four isonitrogenous and isocaloric diets were formulated replacing 0, 50, 75 and 100% of fish meal (FM) by fish silage co-dried with rice bran (CFS). The results of the study for six weeks indicated that, the control group that was fed with feed (0% replacement) made from FM showed highest weight increment with lower feed conversion ratio (FCR) and higher specific growth rate followed by the group fed diet made with 50% replacement of fish meal by CFS. The specific growth rate and feed conversion ratio between 100% and 50% FM-based diets were not significantly different (p<0.05), whereas it was significantly low (p>0.05) with 0% and 25% FM-based diets. The replacement of 50% FM by CFS in L. rohita fingerlings diets did not significantly affect the growth and feed utilisation parameters. Whereas, the higher replacing levels of FM by CFS (75 or 100%) in diets significantly (p<0.05) reduced the growth and feed utilisation parameters
