A diet-change modulates the previously established bacterial gut community in juvenile brown trout (Salmo trutta)

The aim of the present study was to investigate the impact of dietary plant proteins on the gut microbiome of first feeding brown trout ( Salmo trutta ) reproduced from wild stocks and to evaluate whether the initial microbiome of brown trout fry can be permanently manipulated by the first feeding diet. Therefore, brown trout fry was fed diets based on either 0%, 50% or 90% plant-derived proteins from first feeding onwards and via 16S rRNA gene...
