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...

Effects of o,p'-DDE on the immune system of juvenile chinook salmon (Oncorhynchus tshawytscha)

Creator:: Milston, Ruth Helen
Abstract:: Environmental factors such as chemical contamination can have immunomodulatory effects on the immune response of fish and may be contributing to the decline in salmonid populations by augmenting disease susceptibility. Xenobiotics can interfere with the immune system at several levels of complexity, and different immune cells and processes have variable...

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...

The effects of environmental stressors on cardiac gene expression and contractility in rainbow trout (Oncorhynchus mykiss)

Creator:: Momoda, Tracey S.
Abstract:: Rainbow trout (Oncorhynchus mykiss) experience a variety of stressors in their natural environment as well as in aquaculture that can have negative effects on their physiology. The effects of physiological stress and endocrine disruption have been well described in fish. However, there is a scarcity of information on the effects...

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...

The effect of chronic exposure of chinook salmon to benzo(a)pyrene and cortisol of CYP1A1 induction and susceptibility to a microsporidian parasite, Loma salmonae

Creator:: Marie, Amarisa
Abstract:: Wild populations of fish are faced with a multitude of stressors, which may include human interaction, toxins, and disease. Benzo(a)pyrene (BaP), a known carcinogen and immunotoxin, has been reported in the stomach contents of juvenile chinook salmon, Oncorhynchus tshawytscha, in urban waterways. We investigated the impact of chronic dietary exposure...

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...

Behavioral and physiological indicators of stress in sablefish, Anoplopoma fimbria

Creator:: Spencer, Mara L.
Abstract:: The development of assays for stress in marine fishes is vital for studying the impacts of bycatch in fisheries and for determining the health of fish being cultured or used in research. This research developed behavioral and physiological assays for stress in juvenile sablefish, Anoplopoma fimbria, a species that comprises...

Hormonal and osmoregulatory aspects of smoltification in coho salmon, Oncorhynchus kisutch

Creator:: Specker, Jennifer Lee
Abstract:: Coho salmon smolts (Oncorhynchus kisutch) were transported at low and high densities. (12 and 120 g/L) for short and long periods (4 and 12 h). Because smolts can be transplanted directly to seawater, half of the fish in each treatment were transported to tanks containing seawater and half to tanks...

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...
