Relationships between oceanographic factors and the distribution of juvenile coho salmon (Oncorhynchus kisutch) off Oregon and Washington, 1982-1983

Creator:: Chung, Alton W.
Abstract:: Juvenile coho salmon (101-400 mm) were sampled by purse seine off the Pacific Coast from Waatch Point, Washington to Four Mile Creek, Oregon, out to 30 mi offshore, during the months of May, June, and September in 1982 and 1983. Sea surface temperature, surface salinity, surface chlorophyll-a concentration, and Secchi...

Estimated net economic benefits to visitors of selected Columbia River fish hatcheries

Creator:: Larson, Douglas M.
Abstract:: This research has addressed an area of outdoor recreation economics which presents difficulties in estimation of demand and valuation. The focus was on visitors to three Columbia River fish hatcheries, and the net benefits realized from partaking in the recreational/educational experience which fish hatcheries offer. Three characteristics of the recreation...

Relationships between fish species distribution and habitat in the Willamette River drainage in western Oregon

Creator:: Kruse, Amy Ellen
Abstract:: The objectives of this study were to (1) describe physical environmental conditions and species composition at several sites along an Upstream/downstream gradient in a number of tributaries of the Willamette River in western Oregon; and (2) identify possible relationships between species distributional patterns and physical habitat parameters using detrended correspondence...

Biology and production of the red-band trout (Salmo sp.) in four southeastern Oregon streams

Creator:: Kunkel, Clair
Abstract:: The red-band trout is native to many small, isolated streams in southeastern Oregon. A study of the red-band population of Three- mile Creek and Reservoir was conducted from August 1973 to June 1975. Data were collected concerning population size, age composition, growth, biomass, recruitment, fecundity, and habitat. During the spring...

Estimates of genetic variance and heterosis in F₁ winter x spring barley crosses (Hordeum vulgare, L.)

Creator:: Harrabi, Moncef Mohamed
Abstract:: Four winter and four spring barley cultivars along with their F₁ hybrids were grown on the Hyslop Agronomy Farm near Corvallis, Oregon, a high rainfall site (over 1000 mm annually) located in the Willamette Valley. The experiment consisted of four replications. Ten seeds of each F₁ and parents were seeded...

A comparison of three systems of phenotypic selection for grain yield in three spring barley populations

Creator:: Hayes, Patrick M.
Abstract:: Concerns regarding the most effective means of evaluating segregating generations of spring barley prompted this investigation. Three methods of selection were considered: bulk, pedigree, and single seed descent. F₆ lines derived by each method were grown in a replicated yield trial. The effectiveness of each method was measured in terms...
