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...

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...

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...

Ecological influence of bacterial kidney disease on juvenile spring chinook salmon : effects on predator avoidance ability, smoltification, and physiological responses to stress

Creator:: Mesa, Matthew G.
Abstract:: Juvenile chinook salmon (Oncorhynchus tshawytscha) were experimentally infected with Renibacterium salmoninarum (Rs), the causative agent of bacterial kidney disease (BKD), to investigate the effects of BKD on three aspects of juvenile salmonid performance: (1) predator avoidance ability; (2) smoltification; and (3) physiological responses to stress. For these experiments, fish with...

Electrofishing mark-recapture and depletion methodologies evoke behavioral and physiological changes in cutthroat trout (Oncorhynchus clarki)

Creator:: Mesa, Matthew G.
Abstract:: We examined the behavioral and physiological responses of wild and hatchery-reared cutthroat trout Oncorhynchus clarki subjected to a single electroshock, electroshock plus marking, and multiple electroshocking in natural and artificial streams. In a natural stream, trout released after capture by electrofishing and marking showed distinct behavioral changes: fish immediately sought...

Endocrine regulation of final oocyte maturation and sex differentiation in salmonids

Creator:: Fitzpatrick, Martin S.
Abstract:: Sexual maturation and sex differentiation comprise facets of a common theme: reproduction. The endocrine system regulates many of the critical physiological processes necessary for reproduction and offers a framework within which technologies can be developed for controlling sexual maturation and sex differentiation. The studies described in this thesis were undertaken...

Evolution and risk in conservation of Pacific salmon

Creator:: Currens, Kenneth P.
Abstract:: Identifying appropriate units for conservation requires knowledge of evolutionary patterns and risks of managing at different geographical and genetic scales. I examined genetic diversity at different geographical scales among 11,400 rainbow trout (Oncorhynchus mykiss) from 243 locations in 13 major river basins throughout much of their range and among coho...
