Abstract:
The present research was conducted for 60 days to assess the Effect of Mango Leaf meal as Supplementary Feed on Growth and Digestibility of Cyprinus carpio (Linnaeus, 1758) Fingerlings. Between July and November 2022, this experiment was carried out. Mango leaf meal was added to the basal diet at five different levels to create the experimental diets: T₀ (control), T₁ (5%), T₂, T₃, and T₄, which each replaced an equal amount of the basal diet. The fish were given feed 3% of their body weight once every day. The increased weight gain, percent weight gain, SGR, GCE, and lowest (best) FCR, combined with the enhanced proximate composition and digestibility of different treatments, convincingly indicate the efficacy of mango leaf meal supplemented diet. Growth parameters showed a significant difference (p<0.05) in T₃, with weight gain 38.686±0.0352 observed there compared to lowest 31.120±0.2800 in T₀ (control), The highest percent weight (105.491±0.2161), highest SGR (1.200±0.0021), highest GCE (0.398±0.0005), and the best feed use (lowest FCR 2.508±0.0034) were observed in T₃ during the experimental period. Thus, it can be surmised from the above observations that 15% inclusion of mango leaf meal in fish diets can enhance fish development and aquaculture performance.
