In 1979 this study was initiated to determine the distribution, contribution, and value of artificially propagated fall chinook from the Columbia River. Tagging of hatchery fall chinook began in 1979 with the 1978 brood and was completed in 1982 with the 1981 brood of fall chinook at rearing facilities on the Columbia River system. Sampling for recoveries of these tagged fish in the sport and commercial marine fisheries from Alaska through California, Columbia River fisheries, and Columbia River hatcheries and adjacent streams occurred from 1980 through 1986. Estimated recoveries of the tagged fall chinook are available for 1980 through 1984 for most major salmon fisheries on the Pacific coast. Data for 1985 and 1986 are incomplete at this time. Hatchery return data are complete except for a few possible returns of tagged fish in 1987. Enough data are available to examine contributions to the fisheries and total survivals among broods, hatcheries within broods and releases within hatcheries for the same brood. The 1979 brood of fall chinook had the greatest average contribution to the fisheries of 3.9 tagged fish caught for every 1000 tagged fish released. The 1979 brood was followed by the 1978, 1980, and 1981 broods at 2.8, 2.3, and 2.1 tagged fish per 1000 releases respectively. There was considerable variation among rearing facilities within any brood. In the 1979 brood for example, the fishery contribution ranged from 12.7 fish per 1000 releases from Spring Creek Hatchery to 0.3 fish per 1000 releases from Little White Salmon Hatchery. 11 refs., 9 figs., 24 tabs.
