Abstract Silver salmon, Oncorhynchus kisutch (Walbaum), of the 1950 brood year were reared at the Soos Creek Hatchery, State of Washington Department of Fisheries, until January 19, 1952. On that date, approximately 72,000 fingerlings were divided between the State of Washington salmon hatchery on Issaquah Creek and the ponds of the School of Fisheries, University of Washington. After two months of orientation, the two lots of fish were released to migrate to sea on March 18 and 19, 1952. The movement of the fish in the sea were followed by noting the return of the marked fish to the sport and commercial fisheries. Adult salmon returning during the winter of 1953–1954 were examined for marks. None of the marked fish returned to Soos Creek, their native stream. Those fish released at the School of Fisheries returned up the ladder to the rearing ponds and those released at Issaquah migrated to the head of the watershed, returning to the area of release.
