Oncorhynchus mykiss
One of the most beautiful and widely distributed fish in the world, the rainbow trout is named for the brilliant spectrum of colors along its side. Native to cold-water tributaries of the Pacific Ocean, it has been introduced worldwide for sport fishing and aquaculture. The sea-run form, called steelhead, migrates from the ocean to freshwater to spawn — one of nature's most remarkable journeys.
Cold, clear streams, rivers, and lakes with high oxygen content. Steelhead form migrates to the Pacific Ocean and returns to freshwater to spawn.
