Marked yearling hatchery‐reared steelhead smolts were stocked at varying distances from tidewater in two Oregon coastal streams in April of 1964 and 1965 and the numbers of returning adults caught in the sport fishery were determined. Objectives of the study were to determine the preciseness of the homing mechanism in directing the returning adult fish to particular locations in a stream and the contribution to the sport fishery of adult fish of different release origins. Homing imprint was demonstrated to be influenced by stocking site within a stream. A contribution to the fishery of a particular release group was found to be dependent on a delay in upstream migration in the geographic area of stocking and on the fishing effort in the area.
