Prevalence, geographic distribution, and biology of a dungeness crab, Cancer magister, microsporidian parasite

Creator:: Childers, Richard K.
Abstract:: The microsporidian parasite Nadelspora canceri infects Dungeness crabs, Cancer magister, along the United States Pacific Northwest coast. The prevalence and seasonal variation of N. canceri in Dungeness crabs from Alsea Bay, Oregon, are described based on examination of 2991 crabs collected at monthly intervals from October, 1991 to June, 1993....

Bycatch in the ocean shrimp Pandalus jordani fishery

Creator:: Hoover Krutzikowsky, Vicki
Abstract:: The purpose of this research was to explore the impact of finfish bycatch on the ocean shrimp Pandalus jordani fishery using two methods. One method looked at the breakage of the shrimp by finfish bycatch in the nets. The other looked at the impact of bycatch on fishing decisions. At-sea...

Evaluation of length distributions and growth variance to improve assessment of the loggerhead sea turtle, (Caretta caretta)

Creator:: Vaughan, Jason R.
Abstract:: Nest counts from the largest subpopulation of the loggerhead sea turtle (Caretta caretta) in the Atlantic, peninsular Florida, have been declining since 1998. Analyzing trends of nests and adult females is insufficient to determine the overall status of a sea turtle population, due to variation in nesting frequency and a...

Oregon Coastal Residents' Attitudes on Community Participation in Fisheries Management

Creator:: Hanson, Emily E.
Abstract:: The purpose of the research project leading to this paper was to determine if a community management approach to fishery management would be feasible in Oregon. The basis for answering this question was a survey of residents in Oregon's eleven incorporated fishing port communities.

Bioeconomic Simulation Modeling of Fisheries : Three Essays

Creator:: Cusack, Christopher Inju
Abstract:: Researchers rely on bioeconomic models to guide research and generate fishery management advice for commercial fisheries. Due partly to a paradigm shift towards ecosystem based fishery management, increasing complexity in the characteristics of the problems has meant that bioeconomic simulation models are becoming more prevalent in the fisheries literature. However...

Value of Prior and Novel Information in Managing a Mixed-Stock Recreational Chinook Salmon Fishery

Creator:: Jensen, Alexander J.
Abstract:: Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...

Settlement, distribution, growth, and mortality of juvenile dover sole (Microstomus pacificus) off northern Oregon

Creator:: Toole, C. L. (Christopher L.)
Abstract:: Demographic characteristics of juvenile Dover sole (Microstomus pacificus) were examined in relation to physical and biotic factors to develop a hypothesis explaining annual variations in recruitment. Surveys were conducted along the Oregon continental shelf at depths between 50-400 m bimonthly during 1989 and annually (in March) between 1990 and 1993....

Biological and mathematical modeling of dynamics of furunculosis in chinook salmon (Oncorhynchus tshawytscha) and infectious hematopoietic necrosis (IHN) in rainbow trout (Oncorhynchus mykiss)

Creator:: Ogut, Hamdi
Abstract:: A series of experiments with Aeromonas salmonicida and infectious hematopoietic necrosis virus (IHNV) were carried out to determine dynamics of the spread of infection in chinook salmon (1.2-1.98g) and rainbow trout (1.2-3.1g). It was found in experiments with A. salmonicida that fish infected by bath immersion became infectious at 4...

Sea urchin-kelp forest communities in marine reserves and areas of exploitation : community interactions, populations, and metapopulation analyses

Creator:: Moctezuma, Gabriela Montaño
Abstract:: Marine ecosystems can be exposed to natural and anthropogenic disturbances that can lead to ecological failures. Marine reserves have been lately suggested to protect marine populations and communities that have been affected by habitat destruction and harvest. This research evaluates the potential role of two marine reserves established in Oregon...
