  1. The four feeding groups (LS-0: Low-starch with 0 inulin; LS-In: Low-starch with 2% inulin; HS-0: high-starch with 0 inulin; and HS-In: high-starch with 2% inulin) were given to 63 fish per group (3 tanks per group) for 12 weeks. Data are presented as mean ± SD (n = 12 fish). Statistical differences were analyzed with a two-way ANOVA test and were considered statistically significant for P < 0.05
  2. In case of interaction, a post-hoc Tukey’s test was performed (P < 0.05). a,bDifferent superscripts indicated significant differences between groups
  3. NS Not significant, *P < 0.05, **P < 0.01, ***P < 0.001
