Fingerlings of Catla catla, Labeo rohita and Cirhinus mrigala were fed on experimental diets. It is evident by the results that growth is highly affected by dietary ingredients and its level of inclusion in diet. With increasing level of fishmeal, a noticeable decrease in growth was observed, as Control I, II and III produced 67.3 g, 50.5 g and 39.6 g mean weight gain respectively. While opposite trend of growth was observed with APCM based diet i.e., APCM III (45% inclusion of APCM) produced significantly higher growth with a decreased FCR. The two-way analysis of variance for weight, DFA, SGR and FCR against months showed highly significant relationship in all diets. Except moisture and ash, fish carcass composition was significantly affected by protein source and its inclusion level. Keywords : Chicken meal, Carps, polyculture
