Fatty acids of exercised and non-exercised salmon

Creator:: Saddler, James Bryan
Abstract:: The fatty acids of coho salmon were identified and then a study was conducted to determine the effects of exercise on the fatty acids of salmon forced to swim against water velocities of 52, 54, 56, and 59 cm/sec, The shorter and lighter salmon were less competent at a given...

Changes in plasma cortisol concentration of juvenile salmonids during stress

Creator:: Strange, Richard Jackson
Abstract:: I investigated changes in plasma cortisol concentration over time in juvenile salmonids subjected to various stressors that might be encountered in their normal life cycle. This work was directed at finding a general indicator for stress in fish that could be used be used to aid fisheries research and management....

Quality of salmon fry from gravel incubators

Creator:: Poon, Derek Clinton
Abstract:: The performances of newly-established gravel incubation systems designed to use unfiltered water for production of unfed salmon fry were evaluated at Netarts Bay, Oregon, and at Little Port Walter, Alaska. Research was divided into two phases. The first consisted of laboratory studies to develop fry quality testing procedures and to...

A latitudinal cline in the Chinook salmon (Oncorhynchus tshawytscha) Clock gene: evidence for selection on PolyQ length variants

Creator:: O'Malley, Kathleen G. and Banks, Michael A.
Abstract:: A critical seasonal event for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which adults migrate from the ocean to breed in freshwater. We investigated whether allelic variation at the circadian rhythm genes, OtsClock1a and OtsClock1b, underlies genetic control of migration timing among 42 populations in North America. We...

Feeding Ecology and Food Web Linkages of Yearling Chinook Salmon (Oncorhynchus tshawytscha) Migrating Through the Lower Columbia River and Estuary

Creator:: Munguia, Angelica
Abstract:: The Columbia River Basin historically supported abundant populations of Pacific salmon (Oncorhynchus spp.) but, largely due to anthropogenic influence, many populations are now listed as threatened or endangered under the U.S. Endangered Species Act. Habitat restoration efforts have been a critical component of salmon recovery plans. However, although the importance...

Evaluating Fish Rescue as a Drought Adaptation Strategy for Imperiled Coho Salmon: A Life-Cycle Modeling Approach

Creator:: Beebe, Brittany A.
Abstract:: Projected intensification of drought as a result of climate change may reduce the capacity of streams to rear fish, exacerbating the challenge of recovering ESA-listed salmon populations. Without management intervention, some stocks will likely go extinct as stream drying and fragmentation reduce juvenile survival to unsustainable levels. To offset drought-related...

Comparing Migratory Patterns and Survival Between Wild and Wild Fish Surrogate Juvenile Spring Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Pollock, Amanda M. M.
Abstract:: Anadromous salmonid populations in the Pacific Northwest have declined over the past 150 years. In 1999, wild spring Chinook salmon (Oncorhynchus tshawytscha) were federally listed as threatened within the Willamette Basin, OR. Currently, practices to restore wild populations in the upper Willamette Basin involve trapping wild adults at the base...

Using expressed behaviour of coho salmon (Oncorhynchus kisutch) to evaluate the vulnerability of upriver migrants under future hydrological regimes: Management implications and conservation planning

Creator:: Flitcroft, Rebecca, Lewis, Sarah, Arismendi, Ivan, Davis, Chante, Giannico, Guillermo, Penaluna, Brooke, Santelmann, Mary, Safeeq, Mohammad, and Snyder, Jeff
Abstract:: 1. Globally, river systems have been extensively modified through alterations in riverscapes and flow regimes, reducing their capacity to absorb geophysical and environmental changes. 2. In western North America and elsewhere, alterations in natural flow regimes and swimways through dams, levees, and floodplain development, work in concert with fire regime,...

Factors affecting the abundance of fall chinook salmon in the Columbia River

Creator:: Van Hyning, Jack M.
Abstract:: A study of the population ecology of Columbia River fall chinook salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt to determine the cause of a serious decline in this run which occurred in the early 1950's. Fluctuations in abundance of major salmon runs the North Pacific were examined to...
