Brown trout were first introduced to North America in 1883, and have since been found in nearly every Canadian province. In the past, it was believed that brown trout would displace native brook trout, through a combination of predation, competition, and communicable disease. It is now believed that the introduction of brown trout into brook trout streams subject to heavy angling may help to relieve the pressure on brook trout and to allow both species to develop self-sustaining populations. Brown trout are native to Europe and Asia.
