The Ocean Salmon Management Program is responsible for obtaining fishery and biological data, analyzing these data and recommending appropriate management options for the ocean fisheries. Proposed management options are designed to achieve the optimum use of the salmon resource on a sustained basis. The ocean salmon recreational fishery is now...
This report consists of tables summarizing data regarding streams receiving hatchery-reared rainbow trout since 1952. It includes data such as sources, sizes of fish, and water temperatures at the planting sites. It also averages data from creel reports from 1965-1972.
This report the sizes for winter steelhead runs of the Willamette River and many of its tributaries from 1958-69, giving numbers and suggesting possible reasons for small runs.
Results of the first year of the Deschutes summer steelhead ecology and hatchery assessment. “This report covers the first year of a study of Deschutes summer steelhead ecology and factors limiting efficiency of hatchery production of summer steelhead smolts” (Contents).
This report summarizes research on coastal cutthroat trout from the beginning of more intensive studies in 1962 through 1965. Early work involved studies of the growth, survival and catch of hatchery-reared cutthroat in coastal lakes, with a change in 1965 to research in coastal streams and estuaries. Research is continuing,...
This document gives the history of the Striped Bass in Coos County, Oregon. It includes commercial fishing intensity, average weight, and sampling data for 1949 to 1957.
The lower Deschutes River of northcentral Oregon has a historically uniform discharge record. Significant reductions in discharge below the seasonal norms will degrade the environment for migratory and resident salmonids by increasing siltation and gravel compaction, and by reducing intragravel water dissolved oxygen content. Fish spawning will be limited by...
This report discusses public interaction with personal-use fisheries. It also discusses reasons for razor clam violations and means taken to try and decrease them. Finally, it gives the total harvest and age composition data, and contains the results of a survey of clam diggers on Clatsop County beaches for 1965.
Fintrol-5 was experimentally tested in six isolated gold dredge ponds in Sumpter Valley. The tests revealed all coarse fish in treated ponds were killed in a period varying between 7 hours and 144 hours; toxic water subbing from treated ponds would kill fish in downstream ponds if water table dillution...
