The feasibility of a consumptive wild trout sport fishery on the North Fork of the Middle Fork of the Willamette River

Creator:: Nicholas, Jay W.
Abstract:: The objective of this study was to determine whether wild populations of trout in the North Fork of the Middle Fork of the Willamette River can support a catch rate of 0.3-0.5 trout per hour at current levels of effort and to predict how different size and bag limits would...

The physiological response of larval Pacific lamprey to chronic heat stress

Creator:: Carilli, Patrick B.
Abstract:: Pacific lamprey is an important cultural and ecological species to freshwater ecosystems of the Pacific Northwest. Lamprey often rear in low gradient portions of watersheds that have high exposure to climate warming, yet very little is known about their thermal physiology in comparison with other anadromous fishes such as Pacific...

Life histories of juvenile Chinook salmon (Oncorhynchus tshawytscha) in the Columbia River estuary as inferred from scale and otolith microchemistry

Creator:: Campbell, Lance A.
Abstract:: Despite evidence that juvenile Chinook salmon (Oncorhynchus tshawytscha) utilize North Pacific estuaries for growth and salinity acclimation, research in the Columbia River estuary has lead to opposing hypotheses about the estuary’s importance as a salmon rearing environment. Many contemporary tagging studies indicate that salmon residency within the estuary is short...

Factors influencing within-watershed genetic variation of coastal cutthroat trout in Camp Creek, Oregon

Creator:: Wofford, John E.B.
Abstract:: Because human land use activities often result in increased fragmentation of headwater stream habitats, a better understanding of the effects of fragmentation on the genetic heterogeneity of stream salmonids is useful for effective management. We used eight microsatellites to examine the genetic structure of potamodromous coastal cutthroat trout (Oncorhynchus clarki...

Aspects of the early life history of juvenile salmonids in the Dungeness River Estuary

Creator:: Sather, Nichole K.
Abstract:: The decline of many Pacific salmon stocks has stimulated interest in the early life history and habitat requirements of juvenile salmon. Although estuarine habitat associations of juvenile salmon have been investigated in many coastal areas of the eastern Pacific Ocean, until recently, little was known about juvenile salmonid ecology within...

A phenotypic comparison of thirty-eight steelhead (Oncorhynchus mykiss) populations from coastal Oregon

Creator:: Hatch, Keith Martin
Abstract:: An aspect of the genetic structure of coastal Oregon steelhead was explored and found to gradually change in a north to south pattern for the allelic frequencies of several enzymes. Isocitrate dehydrogenase and superoxide dehydrogenase were the clearest examples of this pattern of variation. This pattern was most evident in...

Comparative behavior of the progeny of hatchery and wild steelhead trout (Salmo gairdneri)

Creator:: Bieber, Glen F.
Abstract:: The objectives of this study were to determine whether changes in the selective pressures which occur in a hatchery could cause inherited modifications in the behavior of steelhead trout (Salmo gairdneri) that would affect their survival in the wild. Environmental effects on the behavior of the offspring of hatchery and...

Foraging ecology and reproductive energetics of the Kittlitz's murrelet (Brachyramphus brevirostris) in Southeast Alaska

Creator:: Hatch, Nick R.
Abstract:: The Kittlitz's murrelet (Brachyramphus brevirostris) is a species of conservation concern over the entirety of its known range, which spans coastal Alaska and northeastern Russia. Concerns about the status of the species have been raised due to evidence of population declines in key breeding areas, low reproductive output, and perceived...
