The current practice in the aquaculture industry towards increased replacement of marine ingredients with plant ingredients affects both the natural Se levels and the chemical forms of Se in the feeds. In organisms, the biological functions related to Se are mediated by the expression of selenium-bound proteins, i.e. the selenoproteins. Little is known about the bioavailability of Se in marine-based feed compared to plant-based feed, and how supplementation of Se (e.g. in the form of Se-enriched yeast or other Se-sources) in feeds affect the expression of selenoproteins in farmed fish. The present project will apply novel analytical approaches based on proteomics and advanced trace element analysis for characterising and identifying selenoproteins in fish feed and in farmed Atlantic salmon fed different dietary sources of Se. To date there are few studies on the selenoproteome in Atlantic salmon, and through this project valuable information on how the chemical forms of Se in feeds affect the bioavailability of Se and the selenoprotein expression in fish, will be obtained.
