Principal coordinates (PCo) analysis plots of beta-diversity of gut microbiota of fish fed the experimental diets. The four beta-diversity indices used are; (A) Jaccard distance, (B) Unweighted Unifrac distance (C) Aitchison distance and (D) PhILR transformed Euclidean distance. The samples are grouped by diets; FM—fishmeal-based; SBM—soybean meal-based; 4 experimental diets containing 300 g/kg SBM and 100 g/kg of ICJ—inactivated Cyberlindnera jadinii; ACJ—autolyzed C. jadinii; IWA—inactivated Wickerhamomyces anomalus; AWA—autolyzed W. anomalus diets
