Effects of dietary mannan oligosaccharide (MOS) supplementation in relation to intestinal integrity, microbiota, health and production of cultured fish species

A series of investigations were conducted in order to evaluate the effect of MOS supplementation in finfish aquaculture. Fish with great potential in aquaculture industry were tested with regards to effect of dietary MOS supplementation on intestinal histology and microbiology as well as overall ani...
