Abstract:
A feeding trial of 60 days was conducted to determine the effect of mango leaf meal on digestibility of Cyprinus carpio fingerlings. The fishes were collected from wild habitat and distributed homogenously at the rate of 10 fishes/tank in five treatment group each with four replicates. The five experimental diets (T₀ (control), T₁ (5%), T₂ (10%), T₃ (15%), and T₄ (20%) were made by adding mango leaf meal to the basal diet at five different levels. Each of these diets replaced an equivalent portion of the basal diet. Feeding 3% of body weight was administered to the fish once day. The highest crude protein content in fish carcasses was found to be 16.266±0.0260 in T₃, the highest moisture content in fish carcasses 71.176±0.0480 in T₃, the highest fat content in fish carcasses 5.340±0.2300 in T₃ and the highest carbohydrate content in fish carcasses 4.026±0.0260 in T₁. From the results mentioned above, it can be concluded that adding 15% mango leaf meal to fish diets can improve fish growth and aquaculture output.
