Using remote sensing, in situ observations, and geographic information systems to map benthic habitats at Heceta Bank, Oregon

Creator:: Whitmire, Curt E.
Abstract:: Dramatic declines in many species of demersal fishes off the West Coast have resulted in the designation of nine commercially important species as being overfished. While the causes of those declines are not clearly understood, the fact remains that a paucity of life history and abundance data exists for many...

Management of the red sea urchin fishery : a biological approach

Creator:: Ubeda, Armando J.
Abstract:: The red sea urchin, Strongylocentrotus franciscanus, is one of the three species of strongylocentroids found on the west coast of North America between Baja California and Kodiak, Alaska. It belongs to the phylum Echinodermata, and it is one of the largest species of sea urchins. Since 1970, red sea urchins...

Mapping surficial geologic habitats of the Oregon continental margin using integrated interpretive GIS techniques

Creator:: Romsos, Christopher G.
Abstract:: We map the regional physiography and surficial lithology (Surficial Geologic Habitat or SGH) over the continental margin of Oregon. This thesis develops, describes, and implements an iterative interpretive method to map seafloor habitat types from disparate geological and geophysical datasets including: bathymetric images, sidescan sonar images, seismic reflection profiles, sediment...

Capturing local knowledge for cooperative fisheries management using a participatory geographic information system (GIS) approach in Port Orford, Oregon

Creator:: Wedell, Victoria A.
Abstract:: This study demonstrates the utility of combining available scientific data with local ecological knowledge in a Geographic Information System (GIS) to support community-based fisheries management. The approach used provides both the framework for capturing important ecological, economic and social information relevant to marine fisheries management, and also offers coastal citizens...

Movement and abundance of lingcod (Ophiodon elongatus) in Yaquina Bay Estuary, Oregon: evidence for essential habitat designation

Creator:: Schwager, Tad W.
Abstract:: Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...

Age, growth and maturity of the longnose skate (Raja rhina) for the U.S. west coast and sensitivity to fishing impacts

Creator:: Thompson, Josie E.
Abstract:: In the past, sharks, skates and ray species have mainly occurred in incidental fisheries. Now they are increasingly being directly targeted due to the depleted status of traditionally targeted species. The life history characteristics of many elasmobranch species make them more sensitive to high rates of fishing mortality. The combination...

Mapping a path to sustainable utilization of bay clam resources in Oregon’s 21st century estuaries : an investigation into the potential of Oregon’s commercial bay clam fishery : Report to the Oregon Department of Fish and Wildlife and the Oregon Commercial Bay Clam Industry

Creator:: Endreny, Polly A. and Sylvia, Gil
Abstract:: 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...

Community-based sea turtle monitoring and management at Helen Reef, Hatohobei State, Republic of Palau

Creator:: Barr, Julie M.
Abstract:: Remote areas are frequently homes to regional subpopulations of endangered green sea turtles (Chelonia mydas) and their essential habitat. Local communities are often the users and primary stewards of this valuable and charismatic resource. Recognizing this, a Hatohobeian community group in Palau has engaged in longterm monitoring and conservation management...

Fishermen in Ocean Observing Research

Creator:: Holmes, Susan
Abstract:: Recent observational programs to understand the coastal ocean, like the Oregon Coastal Ocean Observing System (OrCOOS) are under development (www.orcoos.org). A challenge in facing observing systems is achieving spatial and temporal coverage at scales that are useful for ocean modeling. Observational buoys are relatively few and towed arrays and gliders...

Are there two subgroups of albacore, Thunnus alalunga, in the North Pacific? Evidence from variability in catch, seasonal migrations, and length composition for two subgroups in the coastal fishery of North America

Creator:: Barr, Charles M.
Abstract:: North Pacific albacore (Thunnus alalunga) is a highly migratory and commercially valuable species of tuna. All stock assessments and management decisions for North Pacific albacore are presently based on the assumption of a single, uniform stock. However, a growing body of evidence from diverse sources suggests that there are two...
