This study aimed to determine the level of increasing of omega-3 fatty acids EPA, Hepatosomatic Index (HSI), Specific Growth Rates (SGR), and Average Daily Growth (ADG) with the addition of soybean oil to feed as supplement. This research method uses a Complete Randomized Design (CRD) consisting of 4 treatments and 4 tests. The different concentration of soybean oil in the feed were considered as treatment, A (0%); B (2%); C (4%); and D (6%). The test fish used was catfish (Clarias sp) from Bandung Regency, West Java. Feed as much as 2.5% of the biomass weight is given 2 times a day, namely at 07 a.m and 16 p.m for 30 days in a biofloc tank. The conclusion of this study was that the addition of soybean oil showed the best result is in the addition of 4% soybean oil to the feed. The dose showed that the addition of soybean oil as much as 4% to the feed was able to have the best influence on the increase in Omega-3 eicosapentaenoic acid/EPA fatty acids by 25 mg/100g with the highest Hepatosomatic Index (HSI) value of 1.52 ± 0.11, the best Specific Growth rate (SGR) value of 1.1% and Average Daily Growth (ADG) value of 0.27%.
