Abstract The present study was conducted to investigate the effects of dietary bile acid (BA) on the growth performance, body composition, antioxidant responses and expression of lipid metabolism-related genes of juvenile large yellow croaker (Larimichthys crocea) (average weight, 12.00 ± 0.20 g). An optimal lipid diet formulated with 4.0% fish oil and 4.0% soybean oil was set as the positive control diet (MO), while a high-lipid diet formulated with 6.5% fish oil and 6.5% soybean oil was used as the negative control diet (HO). The other three diets were supplemented with 150 (HOB150), 300 (HOB300) and 450 mg/kg (HOB450) BA on the basis of the negative control diet. The results showed that the survival rate (SR) was not significantly different among dietary treatments (P > 0. 05). Compared with the positive control, there were no significant differences in final body weight (FBW) and weight gain rate (WGR) among fish fed diets with high lipid contents. With increasing supplementation of BA in diets, the FBW and WGR gradually increased. Compared with the negative control, fish fed the diet with 300 mg/kg BA had significantly higher FBW and WGR (P
