Relative abundance of most abundant genera in European seabass gut microbial communities when fed the experimental diets, and these were a basal diet with no supplement (CTRL) or supplemented with Gracilaria gracilis powdered biomass at 2.5% (ALGAE2.5), at 5% (ALGAE5) or with the seaweed extract at 0.35% inclusion rate (EXTRACT). Bars and errors indicate mean ± SD of differentially abundant genera (ANOVA, P < 0.05).
