An experimental investigation of the effects of temperature and dissolved oxygen on the growth of juvenile English sole and juvenile Dungeness crab

Creator:: Bancroft, Morgan P.
Abstract:: In the past two decades, occurrences of summertime upwelling-driven low dissolved oxygen (DO) events, or hypoxia, have increased along the northeast Pacific coast. If hypoxic events are severe enough to cause marine species mortality, the areas affected are often called "dead zones." In 2002 and again in 2006, the events...

Validity and Value of Wave Energy Generation as Blackout Risk Mitigation for the Central Oregon Coast

Creator:: Burright, Jeffrey, Clark, Caitlyn E., Johnson, Brandon, and Sharp, Christopher
Abstract:: Energy security is a vital but often unmet requirement for community resiliency. Electricity availability is essential to the functioning of the economy, individual households, and the collective essential services that provide health, safety, and the basic human needs to sustain life. Coastal communities in Oregon face special vulnerability because they...

Effects of Dissolved Oxygen, Temperature, and Dietary Carbon Sources on the Condition of Juvenile English Sole (Parophrys vetulus) from the Oregon Coast

Creator:: Stowell, Michelle A.
Abstract:: Observations of the Oregon coast’s physical oceanography over the last few decades have revealed falling dissolved oxygen levels associated with seasonal upwelling, as well as rising water temperatures. In extreme cases, these changes have been associated with die-offs, redistribution, and decreased abundance and diversity of benthic fish and invertebrates. Many...

Change in Oregon’s Nearshore Groundfish Trawl Fishery: Perspectives from Science and Industry Data

Creator:: Howard, Rebecca A.
Abstract:: The commercial groundfish fishing industry and groundfish research have a long concurrent history of activity on the Oregon continental margin. Within the non-whiting groundfish fishery, the target species are primarily flatfishes, sablefish, lingcod, and rockfishes, though landings of each have fluctuated over time. Recent work shows that over the past...

Pacific Coast Groundfish Fishery Assessment and Management: Incorporating Nearshore Surveys into the Fishery Management Framework

Creator:: Haven, Katlyn M. M.
Abstract:: The Pacific coast groundfish fishery is a diverse, important and lucrative commercial and recreational fishery. Part of this fishery’s monitoring process includes regular fishery-independent surveys for stock assessment. Although these fishery-independent surveys are cost-effective, they are susceptible to scientific uncertainty, and they do not currently sample in nearshore (water depth...

Ecology of Greenland halibut (Reinhardtius hippoglossoides) during the early life stages in the Eastern Bering Sea and Aleutian Islands

Creator:: Sohn, Dongwha
Abstract:: Greenland halibut (Reinhardtius hippoglossoides) have decreased in the eastern Bering Sea and Aleutian Islands since the 1970s. The reasons behind the poor recruitment are unknown, and important knowledge gaps of the ecology of the early life stages have been identified. The objectives of thesis research were (1) to examine geographic...

Marine Neritic and Epipelagic Community Dynamics: An Investigation of the 'Yin' and 'Yang', No-Analog, and Refugia from a Multi-species Perspective

Creator:: Barceló, Caren
Abstract:: Changes in ocean conditions influenced by climatic fluctuations have lead to changes in individual species distributions, which alter the diversity, communities and species interactions across marine ecosystems worldwide. Assessing the species composition and identifying regions and habitats that can safeguard the persistence of biota are critically important. In this dissertation,...

Predicting Fish Recruitment in the Northeast Pacific Using Climate Indices

Creator:: Riley, Shannon L.
Abstract:: Predicting recruitment, which is dependent on parent stock size and climate, is vital for forecasting productivity of fish stocks. The effects of climate can be analyzed via the use of climate indices. Three climate indices, the Pacific Decadal Oscillation, the North Pacific Gyre Oscillation, and the Oceanic Niño Index, describe...

Distribution, Abundance, and Settlement of Slope-spawning Flatfish during Early Life Stages in the Eastern Bering Sea

Creator:: Sohn, Dongwha
Abstract:: Changes in environmental conditions in marine ecosystems could directly or indirectly influence distribution, abundance, settlement, and size at settlement of flatfish. Understanding species-specific and age-specific responses to environmental variability is important for managing commercially important flatfish stocks. Slope-spawning flatfish whose offspring rely on extensive drift from the slope (spawning) to...

Informing and Enhancing Scientific and Management Understanding of Oregon’s Nearshore Groundfish Trawl Fishery by Engaging Local Ecological Knowledge

Creator:: Sjostrom, Anja J. C.
Abstract:: Oregon’s Coastal nearshore ecosystems are a nexus between living marine resources and coincident human recreational, industrial and socio-economic development. These nearshore regions also provide habitats vital to early life history stages of commercial non-whiting groundfish species, which supplied 21% of the Oregon fishing economy in 2018. The very shallow portions...
