A cooperative effort to track Humboldt squid invasions in Oregon

Creator:: Chesney, Tanya A.
Abstract:: Interannual variability of Humboldt squid (Dosidicus gigas) occurrence in the northern California Current System is largely unknown. In Oregon, the distribution of this versatile predator and what is influencing their range expansion from Mexico is poorly understood due to the recent nature of their "invasion" and a lack of monitoring....

A phenotypic comparison of thirty-eight steelhead (Oncorhynchus mykiss) populations from coastal Oregon

Creator:: Hatch, Keith Martin
Abstract:: An aspect of the genetic structure of coastal Oregon steelhead was explored and found to gradually change in a north to south pattern for the allelic frequencies of several enzymes. Isocitrate dehydrogenase and superoxide dehydrogenase were the clearest examples of this pattern of variation. This pattern was most evident in...

Assessment of the potential for conflict between existing ocean space use and renewable energy development off the coast of Oregon

Creator:: Sullivan, Colleen M.
Abstract:: Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing...

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...

Conditions in the Oregon Commercial Fishery Based on the Salmon, Crab and Shrimp Industries from 1967 to 1980

Creator:: Lewis, Mary J
Abstract:: Changes in the Oregon salmon, crab and shrimp fisheries were documented from 1967 to 1980. The related socio-economic conditions in fishing communities were described. Trends indicated that the overall importance of fisheries to port communities has declined and ports are not planning for an increase in the fishing industry. Chinook...

Consumer preferences for seafood information attributes

Creator:: Fonner, Robert C.
Abstract:: Changes in consumer preferences have created a need for developing differentiated and higher valued seafood products. Providing consumers with more information about seafood products at the time of purchase has been suggested as a way of differentiating seafood and promoting healthy fisheries. A discrete choice experiment conducted at high-end grocery...

Contribution of subyearling estuarine migrant coho salmon (Oncorhynchus kisutch) to spawning populations on the southern Oregon coast

Creator:: Nordholm, Katherine E.
Abstract:: The typical coho salmon life history has been characterized by juvenile fish that spend their entire first year in freshwater habitats before migrating into estuaries as smolts. However, reports of early migrating coho fry (age 0), including migration downstream to estuarine habitats, date back to the 1960s. Until a few...

Distribution and assemblages of demersal fish in Oman

Creator:: Ambusaidi, Hilal Saud
Abstract:: The Sultanate of Oman has 1700 km of coastline extending from the Arabian Gulf south to the Arabian Sea. The demersal fish distributions and assemblages have not previously been well defined. In winter, variations in the oceanography of the area are minimal. In summer, however, the Arabian Sea is strongly...

Forest harvest patterns on private land in western Oregon from 1972 to 2002

Creator:: VanNatta, Lisa R.
Abstract:: This project examined the harvest patterns found on private forestland in western Oregon (46000 1cm2) between 1972 and 2002. The research addressed hypotheses concerning the behaviors of different classes of owners as defined by total amount of forestland owned. Existing forest stand disturbance data and ownership data were combined using...

Impacts of Policy and Environmental Change: Understanding Factors of Vulnerability and Resilience in the Face of Change in Oregon Fishing Communities

Creator:: Strawn, Astrea
Abstract:: Commercial fisheries are coupled human-natural systems that cross state borders and integrate private, public, academic sectors and interests. These systems integrate complicated relationships between coastal socioeconomics, resource management and environmental realms. Previous findings from West Coast-based studies have identified aging trends in commercial fisheries participation, commonly referred to as the...

Integration of oceanographic information off the Washington and Oregon coasts into west coast groundfish ecology and fisheries management

Creator:: Juan Jorda, Maria Jose
Abstract:: To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...
