Salmon as food

Salmon is a common food fish classified as an oily fish^[1] with a rich content of protein and omega-3 fatty acids.^[2] Norway is a major producer of farmed and wild salmon, accounting for more than 50% of global salmon production. Farmed and wild salmon differ only slightly in terms of food quality and safety, with farmed salmon having lower content of environmental contaminants, and wild salmon having higher content of omega-3 fatty acids.^[2]
