Sea trout is the common name usually applied to anadromous (or sea-run) forms of brown trout (Salmo trutta), and is often referred to as Salmo trutta morpha trutta. Other names for anadromous brown trout are sewen (Wales), peel or peal (SW England), mort (NW England), finnock (Scotland), white trout (Ireland) and salmon trout (culinary). The term sea trout is also used to describe other anadromous salmonids--coho salmon (Oncorhynchus kisutch), brook trout (Salvelinus fontinalis), Arctic char (Salvelinus alpinus alpinus), cutthroat trout (Oncorhynchus clarkii) and Dolly Varden (Salvenlinus malma). Even some non-salmonid species are also commonly known as sea trout--Northern pikeminnow (Ptychocheilus oregonensis) and members of the weakfish family (Cynoscion). Anadromous brown trout are widely distributed in Europe along the Atlantic and Baltic coasts, the United Kingdom and the coasts of Iceland. They do not occur in the Mediterranean Sea but are found in the Black and Caspian Seas. and as far north as the Barents and Kara Seas in the Arctic Ocean. Brown trout introduced into freshwater habitats in Tasmania, Victoria, New Zealand, Falkland Islands, Kerguelen Islands, Chile and Argentina have established anadromous populations when there was suitable access to saltwater. Anadromous behavior has been reported in the Columbia river and its tributaries in the U.S. and in Canadian rivers on both the Pacific and Atlantic coasts.
