The sample origin and diet effects on the beta-diversity of distal intestinal microbiota in seawater phase Atlantic salmon. The PCoA plots were built on Jaccard (a), unweighted UniFrac (b), Aitchison (c) and phylogenetic isometric log-ratio (PHILR) transformed Euclidean (d) distance matrix, respectively. PCo, principle coordinate; REF, reference diet; IM, insect meal diet; DID, distal intestine digesta; DIM, distal intestine mucosa
