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 animal health and production. Two levels of MOS supplementation were applied 0.2% and 0.4%. Experimental fish were Atlantic salmon (Salmon salar), rainbow trout (Oncorhynchys mykiss), sole (Solea senegalensis) and gilthead sea bream (Sparus aurata). The results from the sea bream studies revealed that MOS supplementation may have a beneficial effect on growth performance of fish greater than 100 g. Additionally, there is a systemic improvement of the intestinal histology for all species investigated, especially when using 0.4% of MOS supplementation level. Both light and electron microscopy revealed increased intestinal surface and improved intestinal integrity of MOS fed fish. MOS alters the intestinal microbiota, ...
