Genus-level composition of the gut, skin and tank water microbiome at the final sampling point, with the samples grouped by treatment in each case. Each bar represents the relative abundance of the top 30 genera, expressed as a percentage of subsampled reads, in one individual fish or water sample. Replicate tank (a/b) and fish identities are indicated in sample name (x axis). Full taxonomy of each genus is included where available (P; phylum, C; class, O; order, F; family; G; genus).
