Efficiency in Oregon's commercial salmon fisheries : a historical perspective

Creator:: Hatley, Thomas Alfred
Abstract:: Historic changes that have taken place on Oregon's commercial salmon fisheries are described in terms of their effects on the efficiency of fishermen. This historical analysis provides a background for comparative efficiency studies of Columbia River gillnetters and ocean trollers with the objective of determining which harvester group was more...

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...

The distribution and aggregation of Chinook salmon stocks on the Oregon Shelf as indicated by the commercial catch and genetics

Creator:: Ireland, Robert
Abstract:: Project CROOS, Collaborative Research on Oregon Ocean Salmon, is a unique partnership of scientists and commercial fishermen that combines catch location data with stock assignments obtained from genetic micro-satellite analysis to investigate the distribution of Oregon Chinook across multiple spatial scales. Using catch data collected by collaborating Oregon troll fishermen,...

Foreign and domestic trade in canned salmon of the U.S. and Canada : the effect on the derived demand of the fishermen

Creator:: Onuorah, Michael Chukwuemeka
Abstract:: The principal objective of the study was first to present a historical discussion of foreign and domestic trade in canned salmon in the United States and Canada, and secondly, to estimate the ex-vessel derived demand characteristics for red and pink salmon facing the fishermen in both countries. Secondary sources were...

Application of multiattribute utility analysis in determining coho salmon policy

Creator:: Walker, Kevin D.
Abstract:: Policy decisions in fishery management are becoming increasingly complex and difficult. This is especially true for the salmon fisheries where policy outcomes affect the productivity of the salmon resource and the subsequent well-being of commercial fishermen, charter boat operators, Indian fishermen, and sport anglers. The objective of this study was...

Growth, residence, and movement of juvenile Chinook salmon within restored and reference estuarine marsh channels in Salmon River, Oregon

Creator:: Hering, David K.
Abstract:: Tidal wetland channels provide rearing habitat for juvenile Chinook salmon as they emigrate from freshwater habitat and prepare to enter the ocean. Widespread diking and drainage of estuarine marshes for agricultural and urban development may have contributed to a decline in salmon abundance in the Pacific Northwest, prompting efforts to...

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...

Changes in size and age at maturity of Columbia River upriver bright fall chinook salmon (Oncorhynchus tshawytscha) : implications for stock fitness, commercial value, and management

Creator:: Beaty, Roy E.
Abstract:: The average size and age of chinook salmon (Oncorhynchus tshawytscha) caught in commercial fisheries along the Pacific Coast of North America have decreased substantially in this century. These declines might be caused in part by changes in size and age at maturity within the stocks contributing to those fisheries. Upriver...
