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,...

Gene expression in the liver of rainbow trout, Oncorhynchus mykiss, during the stress response

Creator:: Momoda, Tracey S.
Abstract:: The extent to which responses to stress are maladaptive or adaptive to the long-term survival of fish remains to be better understood. The aim of this study was to identify differentially expressed genes in the livers of rainbow trout, Oncorhynchus mykiss, responding to an experimental stressor. Gene expression responses were...

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...

Survival and behavior of juvenile steelhead trout (Oncorhynchus mykiss) in two small estuaries in Oregon

Creator:: Romer, Jeremy D.
Abstract:: A number of steelhead (Oncorhynchus mykiss) populations are at risk throughout Oregon, including five populations that are federally listed as threatened or endangered. However, little is known about behavior and survival of these fish as they transition from freshwater to seawater. We investigated whether estuarine survival varies on a temporal...

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...

Pacific lamprey Entosphenus tridentatus : integrating traditional ecological knowledge and contemporary values into conservation planning, and stream substrate associations with larval abundance in the Willamette River Basin, Oregon, U.S.A.

Creator:: Sheoships, Gabe
Abstract:: Pacific lamprey Entosphenus tridentatus is a valuable icon and traditional food source for Indigenous people of western North America. Native Americans have utilized traditional ecological knowledge (TEK) since time immemorial to guide their ways of life, transmitting cultural values and natural history to further generational knowledge. Pacific lamprey are in...

Habitat selection of hatchery and wild juvenile salmonids in Eagle Creek Basin, Oregon

Creator:: Brignon, William R.
Abstract:: To best manage Eagle Creek National Fish Hatchery and minimize any negative impacts that the current hatchery program may be having on Endangered Species Act-listed salmonids in the Eagle Creek Basin, I determined if wild fish are being displaced from preferred habitats by hatchery salmonids Oncorhynchus spp. This thesis had...

Effects of acute stress and exercise on subsequent seawater adaptation and cortisol dynamics in juvenile steelhead trout (Oncorhynchus mykiss)

Creator:: Liebert, Anja M.
Abstract:: The present study investigated the effects of stress and exercise on seawater (SW) adaptation and cortisol dynamics in juvenile steelhead (Oncorhynchus mykiss). To examine the effects of stress, fish acclimated to freshwater (FW) were subjected for 3 hours to confinement stress in FW, and subsequently SW (25 ppt) was introduced...

Stress induced differential gene expression in the brain of juvenile steelhead trout, (Oncorhynchus Mykiss)

Creator:: Schwindt, Adam R.
Abstract:: Gene expression profiles of tissues and cell-lines can be powerful tools for documenting the genetic response to a particular treatment, such as stressors. However, there is a paucity of information on the genetic stress response in the brain. Therefore, we attempted to profile gene expression in the brain of juvenile...
