Steelhead Trout
(Oncorhynchus mykiss)


Recently designated the same genus as the Pacific salmon, steelhead are large rainbow trout that go to sea. Young steelhead spend two to three years in streams developing. In estuaries, larger smolts feed on insects, small crustaceans, and crab larvae. Studies show that steelhead from the Puget Sound area are genetically distinct from other regions. There may also be some genetic differentiation between populations from northern and souther Puget Sound. Even when Puget Sound steelhead migrate to the ocean, they may spend considerable time as juveniles or adults in the protected waters of the Sound.

Returning steelhead fresh out of ocean carry a blue-black spotted back with silver sides and an alabaster belly (known as "chromers"). Fish that spend time in the river return to their traditional colors of a rainbow trout.
