Trout is a ray-finned marine or freshwater fish closely related to the salmon.
The brown trout (sea trout, lake trout and river trout) is widely distributed in Europe. It extends from the Arctic Ocean to the Atlas Mountains in North Africa.
The rainbow trout is native to cold-water tributaries of the Pacific Ocean in Asia and North America.
The steelhead is a sea-run form of the coastal rainbow trout, which can spend two or three years at sea before returning to fresh water to spawn.
Wild-caught and hatchery-reared forms of rainbow trout have been transplanted and introduced for food or sport in at least 45 countries. Aquaculture of the species are major industries in Chile and Australia.
To distinguish a trout from other species, look for a second adipose fin along the back, near the tail.
Sea trout are generally silvery and river trout olive brown, both having spotted fins and sides.
Coloration of rainbow trout varies widely, but all adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males.
The rainbow trout that spend their lives in streams and rivers average between 1 and 5 lb (0.5 and 2.3 kg); others, called steelhead trout, live in the ocean or the Great Lakes for two to three years before returning to fresh water to spawn, and may reach 20 lb (9.1 kg).
Franz Schubert wrote a lied "Die Forelle" (The Trout) about fishing. Later Schubert's Piano Quintet in A major, D. 667 was nicknamed the Trout Quintet because the fourth movement is a set of variations on the composer's earlier "Die Forelle"
The steelhead is the official state fish of Washington.
The biggest ever trout caught by a fisherman was a 73.29-pound lake trout caught by Scott Enloe on May 5, 2023 in Blue Mesa Reservoir in Colorado. The roughly 47-inch fish had a 37-inch girth, which means it was bigger around than the angler himself. Enloe was fishing with his son, Hunter, when he caught the massive trout. The fish was so big that they both needed to work together to pull it into the boat. Enloe released the fish alive after taking measurements and weighing it.

Fishing lakes in remote areas of California are stocked by throwing baby trout out of planes flying over the water at 200 mph.
