Brown Trout
Salmo trutta
Adult brown trout inhabit cool rivers, streams, lakes, and reservoirs, with some populations migrating to sea before returning to fresh water. They are opportunistic predators, eating aquatic insects, crustaceans, smaller fish, frogs, and other prey that can be seized with a fast strike. Adults often hold near undercut banks, boulders, weed beds, or deep pools and rush out to intercept passing food. A notable feature of the species is its flexibility, with resident, lake-running, and sea-running forms all occurring within Salmo trutta.
