Natal source contributions of Pacific cod (Gadus macrocephalus) recruits in the southeastern Bering Sea

Creator:: DiMaria, Ruth A.
Abstract:: Effective and sustainable fisheries management not only depends on identifying and defining stocks (fundamental unit of management), but also on having knowledge of factors influencing the abundance, distribution and connectivity of stocks. Population structure of Pacific cod (Gadus macrocephalus) in the southeastern Bering Sea (EBS) remains unresolved although genetic data...

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...

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...

Management Applications of Remotely Sensed Dynamic Seascapes: Two Case Studies

Creator:: Klajbor, Willem C.
Abstract:: Dynamic seascapes, which are classified using a combination of remotely sensed data and model output, represent a potential tool for dynamic ecosystem-based management in marine systems. This work explores the utility of seascape classification in the context of marine resource management by examining two case studies: one involving biological relationships...

Identifying habitat factors for canary rockfish (Sebastes pinniger) off Washington and Oregon using environmental data and trawl logbooks

Creator:: Vestfals, Cathleen D.
Abstract:: If fisheries managers are to effectively manage commercially exploited fish populations, a basic understanding of the factors that influence fish distribution and abundance is required. In 2005, efforts to identify Essential Fish Habitat (EFH) for the 82 groundfish species managed by the Pacific Fishery Management Council along the West Coast...

Spatial and temporal distribution of juvenile Steller sea lion (Eumetopias jubatus) predation events in the Gulf of Alaska

Creator:: Vazquez, Norma A.
Abstract:: The first objective of this study was to quantify the intensity of space use of 70 juvenile (12-26 months old) Steller sea lions (SSLs) from the western Distinct Population Segment (DPS) in the Kenai Fjord(KF)/Prince William Sound (PWS) region of Alaska as derived from externally attached ARGOS satellite transmitter tags....

Drivers of Euphausiid Abundance and Biomass in the Kitimat Fjord System, BC Canada

Creator:: Qualls, Katelyn M.
Abstract:: Euphausiids are recognized as essential components of marine food webs throughout the world’s oceans due to their role as prey for many species including whales, seabirds, and commercial fishes. The Kitimat Fjord System is an important fisheries area and is the only fjord habitat on the British Columbia coast that...

Bioenergetics individual based model explorations of juvenile coho salmon growth during their first summer on the Oregon shelf

Creator:: Reser, Brendan Alexander
Abstract:: Salmon survival and eventual recruitment success have long been thought to be determined within the first summer following ocean migration. Juvenile growth during this period is largely influenced by ocean conditions such as temperature, prey availability, abundance, and quality. Shifts in these conditions due to climatic perturbations are particularly prevalent...

Unrealized Economic Benefits in the West Coast Non-Whiting Groundfish Trawl Fishery

Creator:: Gann, Aaron K.
Abstract:: In Oregon, commercial fishing is estimated to contribute $544 million in income and 10,000 jobs per year to coastal communities. However not all fisheries are reaching their allocated quotas for catch. In 2017, 187.6 million pounds of non-whiting groundfish trawl quota worth $67 million was not attained, nearly three times...

The Factors Affecting the Diets of Groundfish in the Gulf of Alaska : Ecological and Modeling Considerations

Creator:: Thompson, Kevin A.
Abstract:: Marine systems undergo changes in community composition over time as a result of a variety of environmental and anthropogenic factors. Understanding these community changes and the factors that drive them is critical for ecosystem management of marine resources. The Gulf of Alaska (GOA) is a large marine ecosystem that includes...
