They often live in deep, cold streams or lakes with a current to circulate the water. Estimates of habitat niche Most often, the smallest rainbow trout are found in riffles. Rainbow trout also hybridize with other, less abundant trout species, ultimately impacting the species’ genetic makeup. They often displace native salmonids by outcompeting them for food and habitat. They compete with native brook trout and Atlantic salmon for food and habitat, which can drive native species to migrate away from their native habitats.
