Selenium is an essential element important for anti-oxidant function and is thought to have a protective role against physical stress. The natural Se level in fish feeds based on marine feed ingredient inclusion clearly covers the Se requirement in cultured salmon while also exceeding maximum upper limits. The question is whether this represents a hazard to fish health or food safety or just reflects natural conditions in the marine food web. The future use of alternative feed ingredients of terrestrial origin will reduce the level of the marine based Se and hence require a Se fortification to the natural levels found in marine ingredients to guarantee a strong and robust farmed Atlantic salmon. Such supplementation to the natural marine Se levels is currently not permitted due to exceeding of current Se legislation. The current upper limit of Se in fish feeds limits the replacement of marine proteins with alternative terrestrial proteins that have natural lower levels of Se while maintaining Se levels in fish feeds. Few aquaculture studies exists that form a basis for the current upper safe limit of Se in Atlantic salmon feed. Such upper limit assessment includes fish welfare, food safety (carry-over), and environmental impact. Data from Atlantic salmon experiments are required in order to set appropriate maximum limits in aquaculture feeds. This information includes (1) Selenium speciation in feed and fillet; (2) Carry-over of different forms of Se from feed to the edible part of Atlantic salmon; (3) Environmental impact through loss by faeces; (4) Sublethal toxic effects in fish (fish welfare).
This project aims to provide knowledge on the upper limits for Se in Atlantic salmon feed. Sub aims: (1) Selenium speciation in salmon feeds and Atlantic salmon fillet; (2) Establish Se feed-to-fillet carry-over models; (3) Establish threshold adverse effect levels for Se in Atlantic salmon feeds; (4) Generate knowledge for risk assessment which may forms the basis for recommendations on the current maximum level of Se in Atlantic salmon feeds.
