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...

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...

The adaptive significance of certain enzyme polymorphisms in steelhead trout (Salmo gairdneri)

Creator:: Redding, Joseph Michael
Abstract:: Mean weights, lengths, and condition factors of three isozyme phenotypes of lactate dehydrogenase (LDH) enzyme differed significantly for experimentally reared winter steelhead trout (Salmo gairdneri) fry. Time of emergence from the gravel was unrelated to LDH phenotype. Relative mortality of the phenotypes between eyed-egg stage and emergence was unaffected by...

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...

Effects of steelhead trout (Oncorhynchus mykiss) on chinook salmon (O. tshawytscha) behavior and physiology

Creator:: Kelsey, Denise A.
Abstract:: Three experiments were designed to determine if and how steelhead trout, Oncorhynchus mykiss, may affect chinook salmon, O. tshawytscha, when they are confined together as in a raceway or on a barge. We observed groups of chinook and steelhead together and groups of only chinook in a behavioral experiment to...

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...
