Red drum reared from captive-spawned eggs were used in a 2 × 4 factorial experiment comparing eight diets with soybean oil (SBO) or menhaden oil (MHO) added to a basal diet (about 3.4% lipid from practical ingredients) at 1.5, 5.2, 9.0, or 12.7%. Triplicate groups of 20 early juveniles (mean 0.4 g) were stocked in 1000 litre fiberglass tanks supplied with filtered estuarine water (17–26 °C, mean 22 °C; 15–35‰) and hand fed twice a day to apparent satiation for 56 days. The fish (range 0.3–9.4 g) appeared to utilize up to 1.5–5.2% dietary SBO (in 5.4–8.7% total lipid). With 0.67% EPA + DHA (eicosapentaenoic and docosahexaenoic acids) in the basal diet, no EFA-deficiency signs were observed. Dietary MHO was utilized up to 12.7%, but fish fed diets with more than 1.5% SBO had lower growth rates and increased feed conversion ratios (especially with 9.0 and 12.7% SBO).
