Discussion on the use of escape ports in crab traps

Creator:: Stewart, Nelson E. and Oregon Fish Commission
Abstract:: "Prepared for the State/Federal Dungeness Crab Management Program, Policy Committee Meeting, April 1974." "At the present time most traps used in the Dungeness crab fishery have at least one escape port for the purpose of allowing small crabs to escape. The problem is that there is considerable variation in the...

Discussion on crab mortality associated with certain fishery practices

Creator:: Stewart, Nelson E., Oregon. Fish Commission, and State/Federal Dungeness Crab Management Program
Abstract:: "Prepared for the State/Federal Dungeness Crab Management Program. May 1974." "One of the initial objectives of the State/Federal Dungeness Crab Management Program is to evaluate crab mortality caused by certain fishery practices. The areas of most concern include mortality caused by trawling, handling of softshell and sublegal crabs, lost pots...

Stakeholder evaluation of market based approaches towards managing the adverse impacts of commercial fishing on the marine environment

Creator:: Swart, Brycen
Abstract:: Over fishing, by-catch of non-target fish species, marine mammals, seabirds, and damage to benthic habitats remain serious problems in fisheries management. Management methods based on traditional command and control (CAC) approaches may meet with initial successes yet additional progress is often marginal, requiring managers to implement additional regulations to achieve...

Response of marine stratus to successive polluting events by ships

Creator:: Sechrist, B.
Abstract:: Ship tracks have proven to be an ideal laboratory for studying the response of marine stratocumulus to an increase in aerosol pollution. Here the response of already polluted marine stratocumulus to further pollution was examined by studying the clouds where two ship tracks cross. 78 crossings of ship tracks were...

Diversity of bacterioplankton and plastid SSU rRNA genes from the eastern and western continental shelves of the United States

Creator:: Rappé, Michael Stephen
Abstract:: The phylogenetic diversity of two continental shelf picoplankton communities was examined by analyzing SSU (16S) ribosomal RNA (rRNA) genes amplified from environmental DNA with bacterial-specific primers and the polymerase chain reaction (PCR). Picoplankton populations collected from the pycnocline (10 m) over the eastern continental shelf of the United States near...

The role of selected regulations on the distribution of West Coast groundfish

Creator:: Earley, Jim V.
Abstract:: Expanding groundfish production on the West Coast and in the United States in total, over the past decade, has increased competition in the groundfish market. During the same period, regulations have evolved to control production in the groundfish industry for the purpose of conserving the resource. Other regulations exist to...

Foraging behavior of the Pacific harbor seal (Phoca vitulina richardii) in the Pacific Northwest and potential impacts of coastal hypoxia on foraging efficiency

Creator:: Steingass, Sheanna M.
Abstract:: In the last decade, the California Current Large Marine Ecosystem has experienced a trend of increased severity of upwelling-driven coastal hypoxia. This thesis strove to examine the potential upper trophic level impacts of moderate and severe hypoxia in the CCLME. Initially I conducted a literature review of Pacific harbor seal...

The biology of a shallow-water methane vent

Creator:: Juhl, Andrew R.
Abstract:: In September of 1989, the site of an active seafloor methane vent was confirmed approximately 20 km off the coast of Oregon in shelf waters 135 m deep. The location of the vent had been described to Oregon State University oceanographers by a local commercial fisherman. Preliminary observations in 1989...

Characterizing the response of coralline algae to ocean acidification and nutrient changes in the California Current system

Creator:: Letzing, Sandy
Abstract:: Ocean acidification (OA) has emerged as an important focus of research and policy in this decade. Ocean acidification specifically refers to changes in the inorganic carbon system in the ocean resulting from its absorption of human-released CO₂ from the atmosphere. Anthropogenic atmospheric CO₂ levels are rapidly increasing; much of this...

Evaluating Coastal Protection Services Associated with Restoration Management of an Endangered Shorebird in Oregon, U.S.A.

Creator:: Carroll, Lindsay J.
Abstract:: Coastal sand dunes and beaches offer a variety of ecosystem services such as coastal protection, sand stabilization, species conservation, and recreation. However, the management and balance of ecosystem services offered by dunes and beaches is challenging when ecosystem services interact across the landscape. Management focusing only on one ecosystem service...
