Rainbow trout can be raised in net pens in lakes, in ponds, and in tanks on land. This means that trout can be raised everywhere in Canada, even on the Prairies!

Depending on the type of rainbow trout, it can be raised in freshwater, saltwater, or both.

Until the 1870s, rainbow trout were only present along the Pacific Coast of North America. Humans have now domesticated the fish and introduced it to waterways around the world.
