Two Essays on the Management of the West Coast Salmon Fishery

Creator:: Vasquez-Caballero, Smit
Abstract:: The West Coast salmon fishery presents several complexities that have received little attention in the fisheries economics literature. Two of those complexities are reviewed and analyzed in this dissertation. The first, salmon fishermen participate in alternative fisheries within a season demonstrating a complex switching behavior between different species. Second, the...

Albacore tuna catches in the Northeast Pacific during summer 1969 as related to selected ocean conditions

Creator:: Panshin, Daniel Alexis
Abstract:: Oregon's commercial fishery for albacore tuna (Thunnus alalunga) is large, valuable, and variable. Little is known, however, about the oceanographic factors which determine abundance and distribution of albacore. Primarily using logbook data contributed by fishermen, this study compares albacore catches with selected ocean conditions. The study is limited to troll-caught...

Multiobjective model of the Pacific whiting fishery in the United States

Creator:: Enríquez Andrade, Roberto R.
Abstract:: Pacific whiting (Merluccius productus) is commercially and ecologically one of the most important fishery resources in the Pacific coast of the United States. The fishery is currently going through a period of rapid and profound transformation that could cause a substantial redistribution of benefits among domestic users. Benefits from the...

Life history and evolutionary adaptation of Pacific salmon and its application in management

Creator:: Wevers, Mary Jo
Abstract:: An approach to understanding and managing anadromous salmon, steelhead, and sea-run cutthroat trout (Oncorhynchus spp.) based on life history and evolutionary adaptive capacities of species and stocks is presented. Species, stocks, and local populations are viewed as systems that are continuously adapting to changing environmental conditions. They have the potential...

Determination of quality parameters for the Pacific whiting fishery using neural network and induction modeling

Creator:: Peters, Gregory J.
Abstract:: Pacific whiting, with a maximum sustainable yield between 150,000 and 250,000 metric tons, is the largest stock of fish found off Oregon. The majority of the fish are processed into surimi. Hundreds of variables could potentially affect surimi quality (gel strength). Alternative harvesting and processing input combinations, as well as...

Integrating fleets, markets and ocean dynamics : a bioeconomic analysis of the Oregon ocean shrimp fishery

Creator:: Gallagher, Charmaine Marie
Abstract:: Questions relating to economic performance, biological conservation and variation in resource abundance and harvest of ocean shrimp have led to increasing pressure for management action. Developing effective management policies for this highly variable resource requires a comprehensive understanding of the fishery and marine processes. Important factors in understanding the fishery...

Utilization of wastes from Pacific whiting surimi manufacturing : proteinases and protein hydrolysate

Creator:: Benjakul, Soottawat
Abstract:: Both liquid and solid wastes from Pacific whiting surimi manufacturing were characterized and value-added products were recovered. A proteinase in surimi wash water (SWW) was determined to be cathepsin L with Mr 54,200 on SDS-substrate gel. Heat treatment and acidification shifted the activity zone to M [subscript r] 39,500. No...

Characterization of biochemical, functional properties, and market potential of Pacific whiting fish sauce

Creator:: Tungkawachara, Somjintana
Abstract:: Biochemical properties, functional properties, and market potential of Pacific whiting (PW) fish sauce were investigated. Biochemical properties of fish sauce made from whole fish (W) and a mixture (1:1) of whole fish and surimi byproducts (WB) were compared. Market potential was evaluated through phone interviews and consumer panelists. Proteolysis was...

Regional analysis of the US groundfish fishery : implications of the extended fishery jurisdiction for the Pacific Northwest fishery

Creator:: Adu-Asamoah, Richard
Abstract:: The Fishery Conservation and Management Act of 1976 took effect on March 1, 1977. By this Act the United States extended its management over fisheries to 200 nautical miles from shore. Extended fishery jurisdiction was expected to promote industry development and expand the contribution of the fishing industry to the...

The effect of potassium bromate on the gel-forming ability of Pacific whiting (Merluccius productus) surimi

Creator:: Aguilar, Ramon Pacheco
Abstract:: The abundance and low fat content of Pacific whiting support Its use for the production of surimi. The degradation of muscle proteins by myxosporidian secreted proteinase(s) has been associated with its soft texture. High residual activity is retained through the washing process used in the production of surimi and precludes...
