Mushroom stem-based diets elicit region-specific shifts in rainbow trout gut microbiota.

ABSTRACT: The intestinal microbiota of fish plays a crucial role in host condition and health, exhibiting region-specific functions influenced by dietary components. This study evaluated the effects of mushroom stem meals from Agaricus bisporus (AB), Lentinula edodes (LE), and Pleurotus ostreatus (PO), used as sustainable ingredients on the intestinal microbiota and histomorphology of rainbow trout (Oncorhynchus mykiss). Experimental diets containing 30% mushroom stem meals were tested for 42 days under standard conditions in juvenile rainbow trout (120.1 ± 0.4 g). Mushroom stem meals did not affect the integrity of the intestinal mucosa while inducing a subtle region-specific shift in the intestinal microbial communities. These changes were reflected in intra-individual and inter-individual diversi
