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...

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...
