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...

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...

Cortisol and the immune system of juvenile Pacific salmon during stress and development

Creator:: Maule, Alec G.
Abstract:: Plasma concentrations of cortisol, a glucocorticoid hormone that is immunosuppressive in mammals, increase during stress and smoltification of salmonids. There was a reduction in the ability of lymphocytes to generate antibody producing cells (APC) in vivo concurrent with increased plasma cortisol titers during smoltification of coho salmon (Oncorhvnchus kisutch). Cortisol...

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...

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...

Early development of the endocrine system in salmonids : regulation of sex differentiation and ontogeny of the stress response

Creator:: Floyd, Donald J.
Abstract:: Sex steroids, follicle stimulating hormone (FSH), luteinizing hormone (LH) and gonadotropin releasing hormone (GnRH) were measured in monosex and mixed sex populations of rainbow trout during early development. Steroids declined following fertilization, increased at hatch, then fell and remained constant thereafter. Trends toward differences in steroids between males and females...

Early self-sorting behavior in Chinook salmon is correlated with variation in growth, behavior and morphology later in life.

Creator:: Unrein, Julia R.
Abstract:: Juvenile Chinook salmon (Oncorhynchus tshawytscha) exhibit an array of life history tactics in Oregon's Willamette River Basin, yet we do not know to what extent it is driven by phenotypic plasticity or whether it is predetermined and how conditions in the early rearing environment may affect phenotype expression. We have...
