Microbial composition in the mid-intestinal section at phylum (a) and genus (b) levels after 12 weeks of feeding. In panel b, only the top 15 abundant genera are presented. Feeding groups are symbolized as 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. On panel c, the relative abundance of the Proteobacteria and Firmicutes phyla and the relative abundances of the Ralstonia, Bacillus, and Lactobacillus genus are indicated. Statistical differences were analyzed with a two-way ANOVA test and were considered statistically significant for P < 0.05. Significant differences are represented by asterisk. ^*P < 0.05, ^**P < 0.01, ^***P < 0.001. n = 12 fish per group
