Abstract
Fortification of black soldier fly oil (BSFO) has the potential to improve feed quality through its saturated fatty acid (SFA) content, such as lauric acid and palmitic acid, which play a role in supporting juvenile fish growth. Combining it with squid oil (SQO), which is rich in unsaturated fatty acids, is expected to optimize the growth of juvenile giant gourami. Both oils are still rarely used in juvenile giant gourami feed formulations. This study evaluates the performance of black soldier fly oil and squid oil fortification as a substitute for commercial fish oil in juvenile giant gourami (Osphronemus gouramy) feed. The experiment was carried out under a completely randomized design (CRD) with one factor and four treatments, namely P1 fortified with 6% corn oil and three feed treatments fortified with BSFO and SQO with compositions of 3%:3% (P2 diet), 2%:4% (P3 diet) and 1.5%:4.5% (P4 diet). The parameters observed included feed fatty acid profile, absolute weight gain, survival rate, viscerosomatic index (VSI), hepatosomatic index (HSI), and feed conversion ratio. The results showed that fortifying feed with maggot oil and squid oil could improve nutritional quality and support the growth of juvenile gourami fish. The use of these two oils has the capacity to enhance growth outcomes and survival rate while also supporting the principle of resource circularity through the utilization of environmentally friendly alternative resources as a sustainable source of oil in aquaculture feed formulations.
