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...

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...

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...

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....

Treaty past, treaty present : an interdisciplinary analysis of the Pacific Salmon Treaty through examination of the values, culture and political structures that provide definition

Creator:: Evans, Paul L.
Abstract:: The Pacific Salmon Treaty was established by Canada and the United States to secure sustainability of salmon harvests within the Pacific Northwest. Renewed in June 1999, the treaty functions to legitimize and empower the Pacific Salmon Commission as the agent of fishery sustainability. The Pacific Salmon Commission serves as a...

Evaluation of a U.S. West coast groundfish habitat conservation regulation via analysis of spatial and temporal patterns of trawl fishing efforts

Creator:: Bellman, Marlene A.
Abstract:: Recent emphasis on linkages between essential fish habitat and fish stock productivity has raised concerns about the management of fishing activities such as trawling, which have the potential to impact fish habitat. Knowing specifically where and how intensively trawl effort has occurred over time provides ecologists with the necessary background...

Assessment of the potential for conflict between existing ocean space use and renewable energy development off the coast of Oregon

Creator:: Sullivan, Colleen M.
Abstract:: Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing...
