Physical Climate Variables Associated with California Current Large Marine Ecosystem and Implications in Recreational Fisheries Management

Creator:: Miller, Tiffany A.
Abstract:: Climate variations within the California Current Large Marine Ecosystem (CCLME) have impacts on marine fish populations. It is proposed that these impacts will be reflected in recreational fishing catches which is explored in this study. A Pearson correlation analysis compares data from El Niño Southern Oscillation (ENSO) events and upwelling...

Fish for the Future: Fisheries Conservation Developments and Lessons Learned from Squaxin Tribal, and Washington State, Salmon Fisheries Management

Creator:: Peters, Joseph C.
Abstract:: Washington State fisheries and Washington State Treaty Tribes are becoming increasingly restricted in harvest of wild salmon due to US Endangered Species Act listings of salmon species, marine mammal predation by both ESA listed Southern Resident Killer Whale (SRKW) and US Marine Mammal Protection Act protected pinnipeds, salmon habitat destruction,...

Mapping surficial geologic habitats of the Oregon continental margin using integrated interpretive GIS techniques

Creator:: Romsos, Christopher G.
Abstract:: We map the regional physiography and surficial lithology (Surficial Geologic Habitat or SGH) over the continental margin of Oregon. This thesis develops, describes, and implements an iterative interpretive method to map seafloor habitat types from disparate geological and geophysical datasets including: bathymetric images, sidescan sonar images, seismic reflection profiles, sediment...

Foraging ecology and reproductive energetics of the Kittlitz's murrelet (Brachyramphus brevirostris) in Southeast Alaska

Creator:: Hatch, Nick R.
Abstract:: The Kittlitz's murrelet (Brachyramphus brevirostris) is a species of conservation concern over the entirety of its known range, which spans coastal Alaska and northeastern Russia. Concerns about the status of the species have been raised due to evidence of population declines in key breeding areas, low reproductive output, and perceived...

Evaluation of dungeness crab pots as platforms of opportunity for ocean-observing research

Creator:: Childress, Jeremy L.
Abstract:: Oregon Fishermen in Ocean Observing Research (OrFIOOR) is a cooperative research program between ocean scientists and fishermen in the Pacific Northwest. Dungeness crab fishermen attach sensor packages (temperature and dissolved oxygen) to crab pots. The pots serve as platforms of opportunity for ocean observing. This study examines three principle questions...

Catch per Unit Effort Associated with Species Regulation Changes in Recreational Fisheries Management

Creator:: Frink, Ashley M.
Abstract:: Recreational fisheries regulations at the state level along the US Atlantic coast are constantly changing to ensure the sustainability of marine fish populations. It is hypothesized that effective management of recreational fishing effort should have a positive impact on fish stocks. Using recreational catch per unit effort (CPUE) as a...

On the road to sustainability : Assessing Belize's fisheries management reform using a multiscalar governance approach

Creator:: Wade, Eric A.
Abstract:: The management of small-scale fisheries (SSF) around the world is facing increasing demands for reformation given ecological, social, and economic vulnerabilities. The governance of SSF is particularly important to foster the sustainability of these systems given that it combines regulatory instruments, interactive participation of diverse stakeholders, and the guiding values...

The Effects of Artificial Structures on Estuarine Infaunal Communities and Offshore Biofouling Communities

Creator:: Mendoza, Maritza
Abstract:: For hundreds of years, coastal and marine ecosystems have experienced increasing threats due to the cumulative effects of increasing population growth and dependence on these ecosystems. Thus, there has been increased enthusiasm to mitigate the negative effects of human actions through the use of cleaner sources of energy, like marine...

Accounting for the Effects of Fish Detectability in Fishery-independent Surveys

Creator:: McLeod, Montana
Abstract:: In recent years, there has been an increase in episodic coastal hypoxia along the mid to inner-shelf waters off the Oregon Coast. Wind-driven coastal upwelling events can exacerbate the magnitude of these hypoxic events, causing extremely hypoxic bottom water (<0.5ml l-1 dissolved oxygen) to move onshore towards the inner shelf....

Characterizing Microplastic Ingestion in Black Rockfish (Sebastes melanops) along the Oregon Coast

Creator:: Lasdin, Katherine S.
Abstract:: Microplastics (<5mm diameter) are present in a considerable number of marine and aquatic species. Understanding which species, the global spatial distribution, and what quantities of microplastics are present is extremely important for understanding the potential impacts they could have on recreationally important organisms and for the assessment of risk. We...
