主要參考文獻 Muus, B.J. and P. Dahlström, 1974
附註 Juveniles feed mainly on aquatic insects and crustaceans. At sea the Atlantic salmon is pelagic, usually found feeding near the surface (Ref. 59043) preying on fish and crustaceans (Ref. 35387). May make long distance feeding migrations while at sea (e.g. individuals from European rivers may migrate to rich feeding grounds around the Faeroes Islands and in western Greenland (Ref. 58137)). Adults do not feed in freshwater during the spawning and post-spawning migrations (Refs. 30578, 51442, 59043). Preyed upon by American mergansers, kingfishers, harbor seals, grey seals, sharks, pollock and tuna.
