Evolution and risk in conservation of Pacific salmon

Creator:: Currens, Kenneth P.
Abstract:: Identifying appropriate units for conservation requires knowledge of evolutionary patterns and risks of managing at different geographical and genetic scales. I examined genetic diversity at different geographical scales among 11,400 rainbow trout (Oncorhynchus mykiss) from 243 locations in 13 major river basins throughout much of their range and among coho...

A macroscopic to microscopic study of the effects of barotrauma and the potential for long-term survival in Pacific rockfish

Creator:: Pribyl, Alena L.
Abstract:: Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...

Pacific lamprey Entosphenus tridentatus : integrating traditional ecological knowledge and contemporary values into conservation planning, and stream substrate associations with larval abundance in the Willamette River Basin, Oregon, U.S.A.

Creator:: Sheoships, Gabe
Abstract:: Pacific lamprey Entosphenus tridentatus is a valuable icon and traditional food source for Indigenous people of western North America. Native Americans have utilized traditional ecological knowledge (TEK) since time immemorial to guide their ways of life, transmitting cultural values and natural history to further generational knowledge. Pacific lamprey are in...

Passage, migration behavior, and autoecology of adult Pacific lamprey at Winchester Dam and within the North Umpqua River Basin, Oregon, USA

Creator:: Lampman, Ralph Tatsuo
Abstract:: The extensive reduction in adult Pacific lamprey (Entosphenus tridentatus) counts at many hydroelectric dams in the northwestern USA signals a substantial decline in lamprey numbers across the entire region in the past 40 to 50 years. Among the many potential causes of this decline, obstruction of migration routes has likely...

Phenotypic comparison of hatchery and wild coho salmon (Oncorhynchus kisutch) in Oregon, Washington, and California

Creator:: Hjort, Randy Carl
Abstract:: Phenotypic similarities of coho salmon (Oncorhynchus kisutch) stocks from Oregon, Washington, and California were compared using agglomerative and divisive cluster analyses. The phenotypic characters evaluated included the following: 1) the isozyme gene frequencies of transferrin and phosphoglucose isomerase; 2) the life history characters time of peak spawning and proportion of...

Distribution and movements of Chinook salmon, Oncorhynchus tshawytscha, returning to the Yukon River basin

Creator:: Eiler, John H.
Abstract:: Chinook salmon, Oncorhynchus tshawytscha, returning to the Yukon River basin and other large river systems in western Alaska have declined dramatically since the late 1990s. This continuing trend has raised concerns over the future status of the returns, and severely impacted commercial and subsistence fisheries within the drainage. Management is...

Value of Prior and Novel Information in Managing a Mixed-Stock Recreational Chinook Salmon Fishery

Creator:: Jensen, Alexander J.
Abstract:: Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...

Racial identification of chinook salmon (Oncorhynchus tshawytscha) and juvenile steelhead trout (Salmo gairdneri)

Creator:: Martin, James T.
Abstract:: Efforts to manage stocks of salmonids in Pacific Northwest stream systems are complicated by the occurrence of several runs of a species thought to represent races rearing sympatrically as juveniles. In order to collect the population statistics needed to properly manage these stocks, managers need a method of identifying juvenile...

Behavioral and physiological indicators of stress in sablefish, Anoplopoma fimbria

Creator:: Spencer, Mara L.
Abstract:: The development of assays for stress in marine fishes is vital for studying the impacts of bycatch in fisheries and for determining the health of fish being cultured or used in research. This research developed behavioral and physiological assays for stress in juvenile sablefish, Anoplopoma fimbria, a species that comprises...

Variation in mitochondrial DNA and allozymes discriminates early and late forms of chinook salmon (Oncorhynchus tshawytscha) in the Kenai and Kasilof Rivers, Alaska

Creator:: Adams, Noah Swayambhu
Abstract:: Genetic differences between early and late forms of Alaskan chinook salmon (Oncorhynchus tshawytscha) were identified using two genetic approaches: mitochondrial DNA (mtDNA) analysis and protein electrophoresis. The study populations consisted of early- and late-run chinook salmon in each of the Kenai and Kasilof rivers in Alaska, and a single population...
