Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower...
Recent successes of hatcheries in producing coho salmon have stimulated searches for additional hatchery locations in coastal watersheds. In the past hatcheries were designed with gravity flow water supplies, but in more recent years pumping the water has proven feasible. Because of the acceptance of pumping, naturally impounded waters are...
"Kokanee salmon, Oncorhynchus nerka (Walbaum), are well distributed over much of central and eastern Oregon but are relative newcomers to lakes along the Oregon coast. Kokanee were first introduced into coastal waters in 1952 when 51,802 fry were planted in Woahink Lake, a few miles south of Florence. So far...
The School of Oceanography, Oregon State University, conducted three cruises (May 19-June 2, June 7-22, and September 4-14) in 1982 to study the distribution, abundance, migration, growth and feeding habits of juvenile salmonids during their first summer in the ocean. This is the second year we have had a series...
The Independent Multidisciplinary Science Team (IMST) convened 19 regional leaders in salmon management and research in a workshop on Goals for Recovery of Oregon Coastal Native (OCN) Stocks on August 4-5, 1999. The main purposes of the workshop were to 1) define the concept of recovery and 2) to identify...
Coho salmon have been the most important variety of salmon caught commercially in Oregon. Until recently, coho were also the most common variety in most coastal streams. Based on records from salmon canneries, coho in Oregon north of Cape Blanco (near Port Orford) numbered about 1.25 million adults annually 100...
A study of the scales of Umpqua River spring chinook salmon was made from mid-September to December 1, 1951. The study was undertaken to determine the age composition and probable life history of spring Chinooks in this river. The study was made at the Oregon State College Fisheries Research Laboratory...
