Abstract

The popularity of red nile tilapia (Oreochromis sp.) in aquaculture commodities does not compensate for the cost of its feed. Therefore, the provision of alternative artificial feed that utilizes the availability of local ingredients, effective and efficientis needed. This study aimed to determine the potential effect of two spotted cricket (Gryllus bimaculatus) flour on commercial feed to increase energy and protein retention of red nile tilapia (Oreochromis sp.). This was an experimental study with a completely randomized design, consisting of five treatments and four replications. The addition of two-spotted cricket flour was given in several commercial feeds with different doses; P0 (0%), P1 (2% cricket flour), P2 (4% cricket flour), P3 (6% cricket flour), and P4 (8% cricket flour). The parameters observed were protein retention and energy retention. The data were analyzed using variance analysis (ANOVA) and Duncan’s Multiple Distance Test. The results showed the addition of two-spotted cricket on feed for 30 days had a significant effect (P<0.05) on protein rand energy retention of red nile tilapia (Oreochromis sp.). The highest protein retention was in P4 (83.03%) and the lowest was in P0 (57.04%). Whereas, the highest energy retention was in P4 (5.5174%) and the lowest was in P1 (2.1590%). The addition of two-spotted cricket (Gryllus bimaculatus) on commercial feed with a dose of 8% can increase protein retention and energy for red nile tilapia (Oreochromis sp.)
