Brown trout, or sea trout (Salmo trutta) was first described in 1758 by the Swedish scientist Carl Linnaeus (1707 – 1778). Juveniles swim in rivers, large individuals inhabit lakes (“lake trout”) and the coastal part of seas at depths of up to 28 meters, usually up to 1-2 meters, swimming upstream to the river for spawning. The recorded maximum length is 140 cm. Specimens up to 70 cm long are more common. The maximum weight is 50 kilograms. It feeds on insects, mollusks and fishes.
