Originally a Pacific Coast species, the rainbow has been widely stocked in Ontario and is primarily a lake fish. Spawning occurs after the spring break-up when the fish migrate upstream to gravel beds.
The rainbow trout is a highly regarded gamefish. The difference between the rainbow trout and the steelhead trout is the rainbow lives its entire life in streams. The steelhead is the migratory form of the rainbow trout--meaning it's a rainbow that hatches in a stream or river, migrates to the lake where it lives, feeds, and grows, then migrates back to the original river to spawn. Unlike Pacific salmon, a percentage of these fish survive the spawn and make the migration several times in a lifetime.
