In the present study, various concentration of Moringa oleifera meal was explored as protein source on the growth, body composition and apparent digestibility on Labeo rohita fingerlings. The experimental fish (Labeo rohita) fingerlings with an average body weight of 5.7g were stocked in eight glass aquaria. Twenty two fingerlings were stocked in each aquarium. Four diets designated as treatments; T1, T2, T3, and T4 were prepared on the basis of Moringa oleifera inclusion level as 0%, 10%, 20% and 30% by replacing fish meal and fed to fish at 4% body weight for eight weeks. Highest weight gain (13.01±2.26g) and length increase (3.26±1.43cm) was observed in T1. Significant difference (P ≤ 0.05) was observed in FCR and SGR among the treatments. Better FCR (1.805±0.005) was observed in T1 while poor (3.10±0.0) was observed in T4. Highest SGR (2.14±0.01) was observed in T1 while lowest (1.425±0.025) was observed in T4. Significant (P ≤ 0.05) difference was observed in digestibility of crude protein (CP), fat and fiber among the treatments indicated the ability of Labeo rohita to digest the moringa leaf meal. These results indicated that increase of Moringa oilefera in feed decrease the growth of fish which may be due to the negative effect of some anti-nutrients.
