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...

Bioenergetics individual based model explorations of juvenile coho salmon growth during their first summer on the Oregon shelf

Creator:: Reser, Brendan Alexander
Abstract:: Salmon survival and eventual recruitment success have long been thought to be determined within the first summer following ocean migration. Juvenile growth during this period is largely influenced by ocean conditions such as temperature, prey availability, abundance, and quality. Shifts in these conditions due to climatic perturbations are particularly prevalent...

Impacts of multispecies parasitism on coho salmon (Oncorhynchus kisutch) in Oregon

Creator:: Ferguson, Jayde A.
Abstract:: Diseases caused by parasites are recognized as significant sources of mortality in wild fish populations. I assessed the impacts of multispecies parasitism on a threatened stock of juvenile coho salmon (Oncorhynchus kisutch). A crucial prerequisite to this research was proper identification of parasites, which can be difficult for species lacking...

Effects of beaver on streams, streamside habitat, and coho salmon fry populations in two coastal Oregon streams

Creator:: Bruner, Karen L.
Abstract:: The effects of beaver (Castor canadensis) on stream morphology, riparian zones, and coho salmon (Oncorhynchus kisutch) fry in Cape and Cummins Creeks, Oregon, were examined using stream surveys, vegetation transects, and coho salmon fry counts in 1987. The basin around Cape Creek has been extensively logged since the late 1940's....

Juvenile Coho Salmon (Oncorhynchus kisutch) Diet in Brackish and Freshwater Habitats in the Stream-estuary Ecotones of Coos Bay, Oregon

Creator:: Mackereth, Kailan F.
Abstract:: Loss of lowland estuarine and freshwater off-channel habitats along the Pacific Northwest coast has contributed to the decline of salmonid populations. These habitats serve as nursery grounds for juvenile salmonids providing them with food, winter shelter, and a transition zone between freshwater and saltwater. Lowland areas have undergone anthropogenic alterations...

Contribution of subyearling estuarine migrant coho salmon (Oncorhynchus kisutch) to spawning populations on the southern Oregon coast

Creator:: Nordholm, Katherine E.
Abstract:: The typical coho salmon life history has been characterized by juvenile fish that spend their entire first year in freshwater habitats before migrating into estuaries as smolts. However, reports of early migrating coho fry (age 0), including migration downstream to estuarine habitats, date back to the 1960s. Until a few...

Juvenile coho salmon movement, growth and survival in a coastal basin of southern Oregon

Creator:: Weybright, Adam D.
Abstract:: Juvenile salmonids display highly variable spatial and temporal movement patterns that are influenced by density dependent (e.g., competition, predation) and density independent (e.g., genetics, stream discharge, physical habitat conditions) factors. The effects of these factors differ with fish life history stage, but will ultimately affect how salmonids utilize freshwater nursery...

Winter ecology of juvenile coho salmon (Oncorhynchus kisutch) in modified and unmodified sections of a coastal stream

Creator:: Phillips, Stephen H. (Stephen Homes), 1957-
Abstract:: Natural and gabion modified habitats containing coho salmon (Oncorhynchus kisutch) were observed and measured seasonally in East Fork Lobster Creek, a fifth order stream in western Oregon. Coho salmon usually inhabited backwater and secondary channel pools in winter. Large wood debris complexes and undercut banks were the primary sources of...

Patterns of natural selection and demography in coastal Oregon coho salmon (Oncorhynchus kisutch) populations : evidence from neutral and olfactory receptor gene-linked markers

Creator:: Johnson, Marc Aaron
Abstract:: For Pacific salmon, the evolution of local adaptations depends upon the species' propensity to return, or "home", to natal streams at time of reproduction. Pacific salmon use olfactory cues to guide homing behavior, yet little is known about the genetics of olfaction in salmon. In this study, I use putatively...
