Capture-related stressors impair sablefish, Anoplopoma fimbria, immune system function

Creator:: Lupes, Sarah C.
Abstract:: Sablefish, Anoplopoma fimbria, is a valuable North Pacific Ocean species caught in several commercial fisheries and is often discarded due to size or catch limits. Managers must account for the mortality of discarded fish to assess fish populations and harvest impacts, yet discard mortality rates of specific fisheries are generally...

Distribution and movements of Chinook salmon, Oncorhynchus tshawytscha, returning to the Yukon River basin

Creator:: Eiler, John H.
Abstract:: Chinook salmon, Oncorhynchus tshawytscha, returning to the Yukon River basin and other large river systems in western Alaska have declined dramatically since the late 1990s. This continuing trend has raised concerns over the future status of the returns, and severely impacted commercial and subsistence fisheries within the drainage. Management is...

Effects of atrazine on olfactory-mediated behaviors in Pacific lamprey (Entosphenus tridentatus)

Creator:: Smith, April G.
Abstract:: Pacific lamprey (Entosphenus tridentatus) are experiencing population declines throughout their range. Xenobiotics could be an important risk factor for lamprey populations. Our goal was to establish if common herbicides, as used in forest management, could affect reproductive fitness. We determined that atrazine was a likely compound of greatest concern to...

Linking Moral Obligations, Assumption-based Research, and Structured Decision Making to Inform Bull Trout Recovery

Creator:: Brignon, William R.
Abstract:: More than 1500 species of plants and animals in the United States are listed as threatened or endangered under the Endangered Species Act (ESA). The U.S. Departments of Interior and Commerce are required, under Section 4(f)(1) of the ESA, to develop recovery plans for ESA-listed species under the respective agency...

Interrenal and metabolic responses to stress and their modifying factors in juvenile salmonid fishes

Creator:: Barton, Bruce Alexander
Abstract:: Genetic, ontogenetic, and environmental factors modified characteristic interrenal and glycemic responses to stress in juvenile salmonid fishes. During continuous confinement stress, plasma cortisol rose more quickly in chinook salmon, Oncorhynchus tshawytscha, acclimated to high rather than medium or low temperatures; hyperglycemia following either acute or chronic stress was also highest...

The effects of elevated temperature and stress on immune function in juvenile chinook salmon (Oncorhynchus tshawytscha)

Creator:: Harrahy, Laura Nicole Martini
Abstract:: Stress, including extreme or rapidly changing temperatures, are known to have deleterious effects on fish health and physiology. This thesis examines the combined effects of elevated acclimation temperature and acute handling stress on the number of antibody producing cells, plasma lysozyme concentrations, and the number of pronephric leukocytes in juvenile...

Evolution and risk in conservation of Pacific salmon

Creator:: Currens, Kenneth P.
Abstract:: Identifying appropriate units for conservation requires knowledge of evolutionary patterns and risks of managing at different geographical and genetic scales. I examined genetic diversity at different geographical scales among 11,400 rainbow trout (Oncorhynchus mykiss) from 243 locations in 13 major river basins throughout much of their range and among coho...

Effects of stress on the reproductive performance and physiology of rainbow trout (Oncorhynchus mykiss)

Creator:: Contreras Sánches, Wilfrido M.
Abstract:: The environment under which fish are maintained as broodstock before reproduction is often stressful; however, the impact of stress on broodstock and gamete quality is not well known. We investigated the effects of stress over the final stages (i.e. the 3 months preceding ovulation) of sexual maturation of female rainbow...

A macroscopic to microscopic study of the effects of barotrauma and the potential for long-term survival in Pacific rockfish

Creator:: Pribyl, Alena L.
Abstract:: Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...

Physiological ecology of juvenile Chinook salmon (Oncorhynchus tshawytscha) rearing in fluctuating salinity environments

Creator:: Hackmann, Crystal R.
Abstract:: Estuaries provide juvenile salmonids with highly productive feeding grounds, refugia from tidal fluctuations and predators, and acclimation areas for smoltification. However, these dynamic, fluctuating salinity environments may also be physiologically stressful to growing juvenile fish. In order to evaluate the costs and benefits of estuarine marshes to juvenile Chinook salmon,...
