Feasibility of supplementary sampling of the commercial groundfish landings in Oregon using seafood plant workers

Creator:: Builder, Tonya L.
Abstract:: Fishery dependent data--length distributions, sex ratios, maturity schedules, and species composition of landed catches--are necessary for stock assessments. These data are currently collected by state port biologists using a sampling design that randomly selects samples from a small percentage of a very large target population. Sampling programs may need to...

Bacteriophages Significantly Reduce Mortality of Larval Pacific Oysters Crassostrea gigas from Infection by the Pathogenic Bacterium Vibrio coralliilyticus RE98

Creator:: Madison, David B.
Abstract:: Vibrio coralliilyticus (Vcor) is a bacterial pathogen that is well adapted to shellfish hatcheries and is very pathogenic to the larvae of the Pacific oyster Crassostrea gigas. Vcor has been associated with several large scale larval mortality events in the Pacific Northwest that interrupt the supply of seed oysters available...

Competitive interactions and resource partitioning between northern spotted owls and barred owls in western Oregon

Creator:: Wiens, J. David
Abstract:: The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...

Identification of optimal broodstock for Pacific Northwest oysters

Creator:: Stick, David A.
Abstract:: The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

Redd site selection and spawning habitat use by fall chinook salmon

Creator:: Geist, David R.
Abstract:: The spawning habitat associated with fall chinook salmon (Oncorhynchus tshawytscha) redd clusters was investigated in the Hanford Reach of the Columbia River. A conceptual spawning habitat model is proposed that describes how geomorphic features of river channels create hydraulic processes, including hyporheic flows, that influence where salmon spawn in unconstrained...

Fisherman versus management : perceptions and conflicts in the salmon fishery

Creator:: Mrakovcich, Karina Lorenz
Abstract:: Fishermen's and managers' perceptions of fishery issues are an important factor to consider when studying conflicts between the two groups. According to theories of conflict management, differences in perceptions may cause situations to be characterized by misunderstanding and mistrust, and may add to the difficulties in managing the conflict. A...

The Impacts of Multiple Stressors on Aquatic Invertebrate Communities in the Umatilla River

Creator:: Clark, Hannah
Abstract:: Rivers impacted by human activities often have multiple stressors present. The effects of multiple stressors on biological communities can often be difficult to predict, due to the potential for complex interactions between stressors and communities. This thesis explores the impacts of two stressors often associated with agricultural land use, increased...
