The brown trout (Salmo trutta) is an originally European species of salmonid fish. It includes both purely freshwater populations, referred to Salmo trutta morpha fario and S. trutta morpha lacustris, and anadromous forms known as the sea trout, S. trutta morpha trutta. The latter migrates to the oceans for much of its life and returns to freshwater only to spawn. Sea trout in the UK and Ireland have many regional names, including sewin (Wales), finnock (Scotland), peal (West Country), mort (North West England) and white trout (Ireland).
The specific epithet trutta derives from the Latin trutta, meaning, literally, "trout".
The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates stocks spawn on wind-swept shorelines of lakes. S. trutta morpha fario forms stream-resident populations, typically in alpine streams, but sometimes in larger rivers. Anadromous and nonanadromous morphs coexisting in the same river evidently can be genetically identical. What determines whether or not they migrate remains unknown.

Famous quotes containing the words brown and/or trout:
“His reversed body gracefully curved, his brown legs hoisted like a Tarentine sail, his joined ankles tacking, Van gripped with splayed hands the brow of gravity, and moved to and fro, veering and sidestepping, opening his mouth the wrong way, and blinking in the odd bilboquet fashion peculiar to eyelids in his abnormal position. Even more extraordinary than the variety and velocity of the movements he made in imitation of animal hind legs was the effortlessness of his stance.”
—Vladimir Nabokov (1899–1977)
“The heart beats thick,
Big trout muscle out of the dead cold;”
—Ted Hughes (b. 1930)
