Note: Each data point represents the mean of four replicates (n = 4, mean ± SEM). Means between the CON and the HL groups. Means in each row sharing the different superscripts are significantly different () among the HL, HLLB, and HLHB groups. P_linear means statistical results of orthogonal polynomial contrasts. ns, no significant. The following variables were calculated: survival rate (SR, %) = Nt × 100∕No. weight gain rate (WGR, %) = (Wt − Wo) × 100∕Wo. Specific growth rate (SGR, %d − 1) = (LnWt – LnWo) × 100∕t. Feed conversion rate (FCR, %) = 100 × (total amount of the feed consumed∕(Wt − Wo)). Condition factor (CF, g/cm³) = 100 × (Wt − Wo)∕(body length)³. Hepatosomatic index (HSI, %) = 100 × (liver weight∕Wt). Viscerosomatic index (VSI, %) = 100 × (visceral weight∕Wt). Where Wt and Wo were final body weight (FBW, g) and initial body weight (IBW, g), Nt and No were final and initial number of fish, respectively, and it was the duration of experimental days. Treatment groups: CON, control group; HL, high lipid diets group; HLLB, high lipid diets supplementing with 0.025% bile acid group; and HLHB, high lipid diets supplementing with 0.05% bile acid group.
