Scallop fisheries are often characterized by variable abundance and periodic mass mortality occurrences. Area rotation is a respected management tool for sedentary species. A bioeconomic simulation model that incorporates the spatial and temporal distribution of scallop beds and fishing effort is presented. The model is user-friendly and was designed for...
Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management
indicators tied to outcomes described in management plans or on the achievement of a single objective such as an
increase in the size or number of older, more fecund female fish in a protected...
Stock assessment techniques currently used in the United States are extremely costly to implement, involve significant data requirements, and are inaccessible to all but a few stock assessment scientists. A systematic decrease in fishery yields and the designation of several species as overfished on the west coast of the United...
The traceability practices of 48 seafood businesses were assessed as part of an evaluation of nine global seafood value chains (from harvest to retail). The research was conducted through direct interviews and written surveys in order to assess the reasons why traceability systems were used to strengthen business performance. The...
Fisheries nationwide are facing major challenges that require collection of real time (RT) and near real time (NRT) information. High-resolution RT and NRT data are critical for addressing a variety of fishery needs including quota accounting, observer coverage, bycatch management, electronic logbook and fish ticket requirements, research and monitoring, spatial...
Oregon ocean shrimp annual harvest relies on the successful recruitment and growth of age one shrimp. Changes in oceanic conditions appear to have major impacts on recruitment, spatial abundance and growth rates. Successful recruitment has been identified with the timing and strength of the spring transition generating oceanic conditions favorable...
The role of discounting in determining the optimal harvest of natural resources has been extensively debated in the economic and natural resources literature. Differing approaches to discounting to address sustainability and intergenerational equity issues have the potential to significantly affect the allocation of resources between harvesting and conservation for this...
Understanding seasonal migration and localized persistence of populations is critical for effective species harvest and conservation management. Pacific salmon (genus Oncorhynchus) forecasting models predict stock composition, abundance, and distribution during annual assessments of proposed fisheries impacts. Most models, however, fail to account for the influence of biophysical factors on year-to-year...
This study was commissioned and funded by the Coastal Oregon Marine Experiment Station (COMES) to 1) identify the scientific and management issues constraining the advancement of the Oregon bay clam commercial industry, 2) explore scientific, management, and economic opportunities for the enhancement of the fishery, 3) outline and suggest mechanisms...
Many fisheries management agencies struggle with developing management frameworks that can deliver sustainable
fisheries. Over fishing, by-catch of non-target fish species, marine mammals, seabirds, and damage to benthic
habitats remain serious problems. Management methods based on traditional command and control approaches may
meet with initial successes yet additional progress is...
