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 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...

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...

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...

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...

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...

Passage, migration behavior, and autoecology of adult Pacific lamprey at Winchester Dam and within the North Umpqua River Basin, Oregon, USA

Creator:: Lampman, Ralph Tatsuo
Abstract:: The extensive reduction in adult Pacific lamprey (Entosphenus tridentatus) counts at many hydroelectric dams in the northwestern USA signals a substantial decline in lamprey numbers across the entire region in the past 40 to 50 years. Among the many potential causes of this decline, obstruction of migration routes has likely...

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...
