Steelhead trout are a type of fish belonging to the salmon family, known scientifically as Oncorhynchus mykiss. They are native to the Pacific Ocean and its tributaries, primarily found along the western coast of North America. Steelhead are unique because they can live both in freshwater and saltwater, migrating between the two environments. These fish are recognized for their silvery skin and pinkish stripe along their sides. Steelhead trout are popular among anglers due to their fighting ability and are often sought after for sport fishing. They are also an important species in ecosystems and contribute to the health of aquatic habitats.
