Growth performance and feed conversion ratio (FCR) of fingerlings Catla catla fed on Honey bee pupae meal

The excellent alternative to fish meal is the high dietary value of honey bee pupae meal, a waste product of the apiculture rearing industry. 46-50% of crude protein and 20-30% crude fat in dried pupae make up this premium insect protein source, which also contains a rich, balanced amount of important amino acids. Fish feed facilities are currently looking for additional sources of protein because traditional fish meals are becoming more and more expensive. Four distinct diets were employed to accomplish this goal: one was the control diet consisting of groundnut and maize, while the other three contained 25%, 50%, and 75% protein from the usual diet with honey bee pupae meal. In comparison to 25% and control feed, 50% and 75% honey bee pupae meal was found to have the best results. As a result, the study suggests using honey bee pupae meal in place of fish meal in Catla catla diets, either completely or in parts.
