Creator:: Hastie, James D.
Abstract:: Anadromous fish populations in the Pacific Northwest have undergone substantial change throughout the past century. Historical periods of over-harvest and the construction of numerous dams throughout the region have contributed to declines in the runs of naturally spawning stocks. Management efforts to rebuild fish populations have focused on the restriction...

Creator:: Larkin, Sherry L.
Abstract:: The relationship between intrinsic fish quality (fish condition before handling), production efficiency, product price, and the optimal management of commercial "wild" fisheries was explored in four companion papers. The optimal management plan-consisting of quotas and harvest schedules - would maximize the discounted net industry revenues (NPV) given a minimum biomass...

Creator:: Kingsbury, Leigh
Abstract:: This study used contingent valuation techniques to model the probability of participation in Oregon's CREP as a function of the incentive payment and a vector of socio-economic variables. Possible reasons for non-participation were evaluated and landowner preferences for various program components were assessed. Recommendations for program improvement and implementation were...

Creator:: Watanabe, Michio
Abstract:: The spatial and dynamic pattern of landscape changes has a profound effect on the supply of environmental services, including the provision of habitat for fish and wildlife. Spatial heterogeneity is a common feature of landscapes in the Pacific Northwest, most notably in areas important to the production of salmonid fish...

Creator:: Cerda, Arcadio Alberto
Abstract:: This thesis focuses on the economic efficiency of alternative habitat, streamfiow, and land use allocations within a major drainage of the Pacific Northwest. Specifically, productivity of present habitat and streamfiow conditions is evaluated with respect to anadromous fish species (chinook salmon and steelhead trout) in the John Day River Basin,...
