Effects of microbe- and mussel-based diets on the gut microbiota in Arctic charr

Five experimental diets were fed to Arctic charr (Salvelinus alpinus) to investigate their effects on gut microbiota. The fish meal in a reference diet was replaced with either intact or extracted yeast cells of the species Saccharomyces cerevisiae, the filamentous fungi Rhizopus oryzae or meal from blue mussel (Mytilus edulis). The microbiota was characterised in samples collected from the proximal and distal intestine using 16S rRNA gene amplicon sequencing with Illumina MiSeq.
