Sex and life stage sensitivity of rainbow trout to xenoestrogens

Creator:: Carlson, David B., 1970-
Abstract:: Numerous natural and anthropogenic chemicals interact with endocrine systems of animals. The most widely studied of these endocrine active chemicals (EACs) are estrogen receptor agonists and antagonists. Because of the many important roles of estrogens in animals, xenoestrogens have the potential to impact environmental health. It has been proposed that...

Development of a progeny marker for steelhead

Creator:: Shippentower, Gene E.
Abstract:: This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...

Interaction and behavior of the redside shiner (Richardsonius balteatus) and the steelhead trout (Salmo gairdneri) in western Oregon : the influence of water temperature

Creator:: Reeves, Gordon H.
Abstract:: Water temperature influenced interactions between redside shiners and juvenile steelhead trout (≥1+) in the field and the laboratory. Distribution of the two species within various habitats was determined in three streams with different water temperature regimes. The range of habitats occupied by trout in allopatry at cool temperatures and at...

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...

An Evaluation of the Effects of Hatchery and Management Practices on Geomagnetic Orientation Behavior in Juvenile Pacific Steelhead Trout (Oncorhynchus mykiss)

Creator:: Scanlan, Michelle M.
Abstract:: Numerous populations of salmon and trout undergo extensive migrations, migrating from freshwater to the sea and throughout ocean basins. Years later they return to their natal streams with remarkable accuracy and precision. The outward migration is accomplished without the benefit of following experienced migrants or prior individual experience. Evidence suggests...

An evaluation of the effectiveness of instream structures for steelhead trout rearing habitat in the Steamboat Creek basin.

Creator:: Fontaine, Barbara L.
Abstract:: Several types of instream structures were evaluated for their potential to provide rearing habitat and to increase reach carrying capacity for steelhead trout (Salmo gairdneri). Evaluation was conducted in each season over the course of 1 year. Blast pools created in bedrock glides increased the carrying capacity of stream reaches...

Reconnecting aquatic habitats : validating historical habitat use by anadromous fishes using telemetry and stable isotope analysis above barriers

Creator:: Lewis, Sierra Koch
Abstract:: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My...

A comparative study of fish coloration and toxicant responses in a chromatophore cell-based biosensor

Creator:: Roach, Holly B.
Abstract:: Detection of both biological and chemical environmental toxicants is essential in the assessment of risk to human health. Cell-based biosensors are capable of activity- based detection of toxicity. Chromatophore cells, responsible for the pigmentation of poikilothermic animal, have shown immense potential as cell-based biosensors in the detection of a broad...
