【 摘 要 】

High price of fish meal for artificial feed provides an alternative solution to use maggot meal as fish meal substitute for decreasing production cost, because it is cheaper and easier to be obtained. The study aimed to determine and analyze the substitution of fish meal with maggot meal derived from various wastes as artificial feed, for improving carp (Cyprinus carpio) production and quality. The study used experimental method with completely randomized design (CRD). This study used four treatments and three replications. About 120 of carps with 0.62±0.14 g/fish of average individual weight maintained at 1 fish/L of stock density for 45 days. Pellet-shaped feed with 30% of protein content was used. The feed was given to tested fish with fixed feeding rate three times a day. The treatments conducted in this study were: 150g/L tofu waste (A); 50g/L fruit waste + 100g/L tofu waste (B); 50g/L vegetable waste + 100g/L tofu waste (C); 50g/L chicken manure + 100g/L tofu waste (D). Primary data were Total Feed Consumption (TFC), Feed Utilization Efficiency, Protein Efficiency Ratio (PER), Specific Growth Rate (SGR), and Survival Rate. The result of fish meal substitution with maggot meal for artificial feed which cultured with 50g/L chicken manure + 100g/L tofu waste gave a significant effect (P0.05) on TFC. The results were 74.93±0.91 of feed utilization efficiency, 2.24% of protein efficiency ratio, 2.81% of specific growth rate, and 91.11% of survival rate. The best lysine amino acid profile was 32.83%, and the highest linoleic fatty acid was 7.26%.
