'''Steelhead''', or occasionally '''steelhead trout''', is the [[Fish migration#Classification|anadromous form]] of the [[coastal rainbow trout]] {{nowrap|(''Oncorhynchus mykiss irideus'')}} or [[Columbia River redband trout]] (''O. m. gairdneri'', also called '''redband steelhead''').<ref name=Behnke2002-67>{{cite book |last=Behnke |first=Robert J. |others=Tomelleri, Joseph R.

Like other sea-run (anadromous) [[trout]] and [[salmon]], steelhead [[spawn (biology)|spawn]] in freshwater, [[Juvenile salmon|smolts]] migrate to the ocean to forage for several years and adults return to their natal streams to spawn.  Steelhead are [[iteroparous]], although their survival rate is approximately only 10–20%.<ref name=Behnke2002-76>{{cite book |last=Behnke |first=Robert J. |others=Tomelleri, Joseph R.
