Prespawning Mortality of Fall Creek Willamette Chinook Salmon (Oncorhynchus tshawytscha): Evaluation of the Effects of a New Trap at the Adult Fish Collection Facility

Creator:: Carey, Katherine
Abstract:: Annual rates of prespawn mortality (PSM) in adult Chinook salmon (Oncorhynchus tshawytscha) trapped and transported upstream of dams in the Willamette River basin are high (often >40%) and could limit the ability to restore natural populations of spring Chinook salmon if not reduced. Improvements at the U.S. Army Corps of...

Development of a Structured Adaptive Approach to Klamath Basin Sucker Recovery Planning

Creator:: Barajas, Miguel F.
Abstract:: Listed as endangered in 1988, the Lost River sucker (Deltistes luxatus) and Shortnose sucker (Chasmistes brevirostris) were once abundant and widely distributed in the Klamath Basin in Southern Oregon and Northern California. Populations of both species have been declining since the late 1960’s. Factors thought responsible for declines include naturally...

Influence of Novel Ocean Conditions on Life History Characteristics of a Nearshore Rockfish with Implications for Population Assessment and Management

Creator:: Rosemond, Rebecca C.
Abstract:: The California Current Large Marine Ecosystem (CCLME), located on the eastern boundary of the North Pacific Ocean, is highly dynamic, with variable conditions driven by seasonal upwelling, regional oceanography, and broad scale climate patterns. In the last decade, the northeast Pacific Ocean has experienced several marine heatwaves (MHWs), prolonged periods...

Maternal effects, the environment, and age structure: A mechanistic fine-scale approach to describe a complex set of factors contributing to larval growth and survival

Creator:: Arnold, Linsey M.
Abstract:: The relationship between population characteristics and population productivity is fundamental to sustainable fisheries management, but predicting productivity remains a challenging task. Proposed mechanisms driving the variability in productivity at a given population size have included environmental and demographic factors related to the age structure of the population, but the broad-scale...

Investigating Demographic and Evolutionary Factors Important for Fish Reintroduction

Creator:: Sard, Nicholas M.
Abstract:: Reintroduction programs are used to re-establish species back into their historical habitat. Most reintroduction programs have failed and few papers have evaluated factors that may be important to Pacific salmon. The 158 meter tall Cougar Dam has blocked Chinook salmon (Oncorhynchus tshawytscha) from accessing 40 kilometers of historical spawning and...

Big Fishery, Big Data, and Little Crabs: Using a Genomic Approach to Examine Larval Recruitment Patterns of Dungeness Crab (Cancer magister) in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J.
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. In this thesis, a genotyping-by-sequencing (GBS) approach was used to examine genomic variation in an early life stage of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...

Bioenergetic evaluation of diel vertical migration by bull trout

Creator:: Eckmann, Madeleine
Abstract:: I evaluated hypotheses related to growth as a driver of depth use and diel vertical migration by bull trout (Salvelinus confluentus) in a thermally stratified reservoir. I applied a bioenergetic model to evaluate growth of bull trout in relation to potential patterns of diel depth use by bull trout in...

Oxygen consumption during acclimation to increasing salinity in the freshwater euryhaline cichlid Oreochromis niloticus (Linnaeus, 1757)

Creator:: Alablani, Salam A.
Abstract:: Two sets of experiments measured changes in the oxygen consumption of the euryhaline teleost Oreochromis niloticus during acclimation to progressively increased salinity. Six acrylic respirometers were constructed for this purpose. The salinities tested were 9, 18, 27 and 36 ppt, with 36 ppt considered as full strength seawater. Fish were...

Evaluating the data-poor fishery stock assessment method, DB-SRA

Creator:: Owashi, Brandon R.
Abstract:: Depletion-Based Stock Reduction Analysis (DB-SRA; Dick and MacCall, 2011) is a catch-only fisheries stock assessment model that has been developed to estimate an overfishing limit (OFL) in data-poor situations. DB-SRA projects the biomass trajectories of a stock by means of a catch time series and five parameters: the instantaneous, per...

Habitat selection of hatchery and wild juvenile salmonids in Eagle Creek Basin, Oregon

Creator:: Brignon, William R.

Mortality threshold for juvenile Chinook salmon (Oncorhynchus tshawytscha) in an epidemiological model of Ceratomyxa shasta

Creator:: Ray, R. Adam
Abstract:: The myxozoan parasite, Ceratomyxa shasta, is the most significant pathogen of juvenile Chinook salmon (Oncorhynchus tshawytscha) in the Klamath River, CA, USA. This parasite requires two hosts - a freshwater polychaete (Manayunkia speciosa) and a salmonid - to complete its life cycle. The complex life cycle and large geographic area...

Seasonal dynamics of a riparian food web in the Oregon Coast Range mountains

Creator:: Robillard, Amanda Lynn
Abstract:: Riparian areas are eco-tones where aquatically- and terrestrially-derived insect biomass is exchanged between habitats, presenting consumers with new sources of energy, and resulting in a reciprocal subsidy. The relative contribution of energy exchange and the resulting impacts on vertebrate riparian consumers, such as fish or birds, remains poorly understood. We...

Genetic patterns of demography and diversity in eastern North Pacific rockfishes (genus Sebastes)

Creator:: Johansson, Mattias L.
Abstract:: The 100 North Pacific rockfish species in the genus Sebastes are highly diverse. Rockfishes fertilize their eggs internally and release swimming larvae. Complex courting behaviors may allow female rockfish to be selective about their mates and may promote and maintain speciation. In this study, I applied genetic techniques to survey...

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...

Modeling abiotic influences on disease dynamics for the complex life cycle of the myxozoan parasite Ceratomyxa shasta

Creator:: Ray, Robert Adam
Abstract:: Most parasites and their hosts live in a balance within their environment; however a disease outbreak can occur when either the parasite, host, or environment, are perturbed. Myxozoan parasites are associated with a wide variety of cultured and wild fish populations. Most myxozoans are relatively benign to their vertebrate host;...

Ecological Effects of Reservoir Water Level Management and Implications for Juvenile Chinook Salmon

Creator:: Murphy, Christina A.
Abstract:: Large dams and their respective reservoirs can provide renewable energy and water security, but also profoundly alter riverine ecosystems. In the Pacific Northwest, dams and reservoirs cause discontinuities in river networks that have been particularly problematic for anadromous fishes. As barriers to the upstream and downstream migration of anadromous fishes,...
