Found in streams, ponds, rivers and lakes. Individuals spend 1 to 5 years in fresh water and 6 months to 5 years in salt water. Lacustrine populations undertake migration to tributaries and lake outlets to spawn. Spawns in rivers and streams with swift current, usually characterized by downward movement of water intro gravel. They prefer cold, well-oxygenated upland waters although their tolerance limits are lower than those of rainbow trout and favors large streams in the mountainous areas. Each female produces about 10.000 eggs. Sea and lake trouts forage in pelagic and littoral habitats, while sea trouts mainly close to coast, not very far from estuary of natal river. Juveniles feed mainly on aquatic and terrestrial insects; adults on mollusks, crustaceans and small fish. Marketed fresh and smoked; eaten fried, broiled, boiled, cooked in microwave, and baked.
