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...

Oregon coastal salmon spawning surveys and straying of private hatchery coho salmon from Yaquina and Coos bays

Creator:: McGie, Alan M. and Oregon. Dept. of Fish and Wildlife. Research and Development Section
Abstract:: In addition to standard spawning surveys for coho salmon, this report contains additional sampling in the Yaquina River, at the Salmon River Hatchery and tributaries of Coos Bay "to document straying of private hatchery coho salmon from the Oregon Aqua-Foods (OAF) facility at South Beach, Yaquina Bay, and Anadromous, Inc.,...

Regions to streams : spatial and temporal variation in stream occupancy patterns of coho salmon (Oncorhynchus kisutch) on the Oregon coast

Creator:: Flitcroft, Rebecca L.
Abstract:: Aquatic ecological investigation is expanding to encompass considerations of multiple scales across large landscapes. Much of the analysis included in this work focuses specifically on coho salmon (Oncorhynchus kisutch) in multiple subbasins on the Oregon coast. Coho salmon were chosen for an investigation of spatial scales, network connections, and life...

Seasonal changes in distribution and abundance of salmonids and habitat availability in a coastal Oregon basin

Creator:: Sleeper, Jack David
Abstract:: Visual estimation techniques were used to quantify habitat characteristics, habitat type (pool, riffle) use and longitudinal distribution of steelhead (Oncorhynchus mykiss), cutthroat trout (0. clarki), and coho salmon (0. kisutch) in spring, summer and fall in 8.8 km of Cummins Creek, a basin in the central coast of Oregon. Fish...

Climate warming effects on the life cycle of the parasite Ceratomyxa shasta in salmon of the Pacific Northwest

Creator:: Chiaramonte, Luciano V.
Abstract:: Aquatic ecosystems continue to be increasingly affected by climate warming. For salmonids in the Pacific Northwest of North America, increasing temperatures pose tighter thermal constraints on their habitat use as well as aspects of their individual performance, such as disease resistance. This thesis examines the effect of temperature on the...

Basin-scale variation in the spatial pattern of fall movement of juvenile coho salmon in the West Fork Smith River, Oregon

Creator:: Hance, Dalton J.
Abstract:: from the summer dry season to the winter wet season. Such movement that connects summer and winter habitats may be particularly important for coho salmon, O. kisutch, because availability of overwintering habitat can limit freshwater survival for this species. Here, I describe basin-scale variability in the spatial pattern of fall...

Multiscale assessment of thermal patterns and the distribution of chinook salmon in the John Day River Basin, Oregon

Creator:: Torgersen, Christian E.
Abstract:: This study examined the distribution and behavior of adult spring chinook salmon (Oncorhynchus tshawytscha) related to patterns of stream temperature and physical habitat at channel unit, reach, and basin-wide spatial scales in both a wilderness stream and a disturbed stream in the John Day River basin in northeastern Oregon. Thermal...

The distribution and aggregation of Chinook salmon stocks on the Oregon Shelf as indicated by the commercial catch and genetics

Creator:: Ireland, Robert
Abstract:: Project CROOS, Collaborative Research on Oregon Ocean Salmon, is a unique partnership of scientists and commercial fishermen that combines catch location data with stock assignments obtained from genetic micro-satellite analysis to investigate the distribution of Oregon Chinook across multiple spatial scales. Using catch data collected by collaborating Oregon troll fishermen,...

Assessing landscape complexity using remotely sensed and field based measurements : does landscape complexity drive leafroller parasitism rates on Oregon caneberry farms?

Creator:: Winfield, Tammy L.
Abstract:: Landscape heterogeneity is thought to differ among farm management types (i.e. organic and conventional), and this difference is hypothesized to result in variations in pest control by natural enemies. However, it is unclear if these variations in pest control are driven by landscape structure or by farm management practices themselves....
