Beta diversity results of mucosal gill microbiomes of farmed Atlantic salmon. PCoA plots of Beta diversity measurements (A) Bray–Curtis dissimilarity of all Atlantic salmon (B) Unweighted Unifrac of all Atlantic salmon (C) Unweighted Unifrac of hatchery Atlantic salmon (D) Unweighted Unifrac of seawater farmed Atlantic salmon. Difference colours indicate difference sites, while ellipses represent 95% confidence interval of standard error of groups. Icons indicate salmon rearing unit. Hand drawn lines divides freshwater and seawater groups in A & B. FT = Flowthrough, RAS = Recirculating aquaculture system and Loch indicates water system of each hatchery and hatchery of origin for seawater sites
