This paper presents a list of more than 200 references on topics associated with offstation releases of hatchery stocks of anadromous fish used to supplement or reestablish wild rearing. The narrative briefly reviews influences of genetics, rearing density of fish in the natural environment, survival rates observed from outplanted stocks, and estimation procedures for stocking rates and rearing densities. We have attempted to summarize guidelines and recommendations for fishery managers to consider. Based on tagging studies, a typical smolt release from a Willamette River hatchery would return 0.29% of the smolts to the stream of release as adults. Catch to escapement ratios for adult Willamette chinook vary widely between broods, but on average two fish are caught for each fish that escapes. The catch is about evenly divided between offshore and freshwater harvest. British Columbia is the primary location of offshore harvest, and the lower Willamette River is the primary location of freshwater harvest. Review of departmental policy indicates that only Willamette stock spring chinook are currently acceptable for use in a proposed outplant study within the Willamette basin. Further, most Oregon Department of Fish and Wildlife district management biologists would prefer not to transfer any stocks of spring chinook between drainage subbasins. State fishery managers identified 16 Willamette basin streams as being suitable for supplementation with spring chinook from hatcheries. We reviewed the potential for rearing salmon in reservoirs throughout the basin. Use of the Carmen-Smith spawning channel, which was constructed on the upper McKenzie River in 1960, has generally declined with the decline in populations of chinook salmon in this river. The Carmen-Smith channel still provides a spawning place for those relatively few adult chinook that still return each year, but more fishery benefits may result from other uses of this facility. 7 figs., 8 tabs.
