As global protein consumption rises, fish protein has become an important component of food security. However, the scarcity of fishmeal necessitates the development of sustainable aquaculture solutions based on cost-effective plant-based alternatives. This study investigates the growth performance of replacing fishmeal with 0%, 30%, and 45% mixtures of Moringa oleifera leaf meal and Leucaena leucocephala leaf powder in the diet of pangasius and common carp. Each of the three-tank contained 5:1 pangasius and common carp, with an average weight of 2.80 ± grams. Protein efficiency ratio (PER), feed conversion ratio (FCR), feed conversion efficiency (FCE), growth, survival rate, and specific growth rates (SGR) of pangasius and common carp were evaluated. The results of the study showed that the (T2) diet, which, had the lowest FCR and the highest mean weight growth, SGR, PER, and FCE.With a maximum survival rate, as compared to T1 and control. According to the current study’s findings, the growth performances of pangasius and common carp were considerably impacted by the substitution of 30% and 45% Moringa oleifera and Leucaena leucocephala leaf meal.
