Effects of Current Hatchery Practices on Salmon Odor Recognition and Responses

Creator:: Lemanski, Joseph R.
Abstract:: Salmon hatcheries have been utilized throughout the Pacific Northwest for many decades to mitigate losses, supplement natural spawning populations, and to provide tribal, sport and commercial fishing opportunities. Currently, there is substantial debate on their efficacy and the potential threats hatchery-reared salmonids pose to natural populations. These concerns have lead...

Factors Affecting the Efficacy of Depuration for Decreasing Vibrio parahaemolyticus Contamination in Pacific Oysters (Crassostrea gigas)

Creator:: Hou, Yishu
Abstract:: Vibrio parahaemolyticus is a foodborne pathogen recognized as the leading cause of acute gastroenteritis associated with consumption of raw and undercooked seafood, particularly raw oysters, with major symptoms of nausea, vomiting, abdominal cramps and diarrhea. It is estimated that 45,000 cases of V. parahaemolyticus infection occur each year in the...

Cooling characterization and practical utilization of sub-micron slurry ice for the chilling of fresh seafood

Creator:: Keys, Dustin R.
Abstract:: Consumption of seafood products continues to grow each year, but post-harvest losses and inedible seafood waste remain as high as 25%. Ice-based systems are the most common form of preservation to increase shelf life, preserve product quality, and enhance product safety. Slurry ice is a type of chilling media, consisting...

Contribution of subyearling estuarine migrant coho salmon (Oncorhynchus kisutch) to spawning populations on the southern Oregon coast

Creator:: Nordholm, Katherine E.
Abstract:: The typical coho salmon life history has been characterized by juvenile fish that spend their entire first year in freshwater habitats before migrating into estuaries as smolts. However, reports of early migrating coho fry (age 0), including migration downstream to estuarine habitats, date back to the 1960s. Until a few...

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...

Exploring perceptions and experiences of the U.S. West Coast shellfish industry dealing with ocean acidification

Creator:: Mabardy, Rebecca Anne
Abstract:: Nearshore and estuarine environments along the U.S West Coast are ocean acidification (OA) "hotspots". Carbon dioxide-enriched water has been correlated with production losses of Pacific oyster (Crassostrea gigas) larvae at hatcheries in the Pacific Northwest. Limited and unreliable supply of larval seed has implications for the economic well-being of commercial...

Development of the fisheries of the Eastern North Pacific : a natural-cultural systems perspective

Creator:: Deimling, Elisabeth A.
Abstract:: The eastern margin of the Eastern North Pacific Ocean was classified into physiographic regions based on a suite of physical characteristics. Information on cultural and biological characteristics of this area was meshed with this classification. The result was a classification of the Eastern North Pacific into natural-cultural systems whose boundaries...

A cooperative effort to track Humboldt squid invasions in Oregon

Creator:: Chesney, Tanya A.
Abstract:: Interannual variability of Humboldt squid (Dosidicus gigas) occurrence in the northern California Current System is largely unknown. In Oregon, the distribution of this versatile predator and what is influencing their range expansion from Mexico is poorly understood due to the recent nature of their "invasion" and a lack of monitoring....

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...
