Ecosystem Functions of Pacific Northwest Estuaries: The Role of Ocean and Watershed Drivers in Eelgrass and Coho Salmon Dynamics

Creator:: Magel, Caitlin L.
Abstract:: Interest is expanding for the potential role of estuaries, particularly seagrass and salt marsh habitats, to sequester carbon, mitigate ocean acidification, and support abundant fisheries. The important functions of estuaries are part of a broader set of ecosystem services, or benefits to humans, which are regulated by ocean and watershed...

Redd site selection and spawning habitat use by fall chinook salmon

Creator:: Geist, David R.
Abstract:: The spawning habitat associated with fall chinook salmon (Oncorhynchus tshawytscha) redd clusters was investigated in the Hanford Reach of the Columbia River. A conceptual spawning habitat model is proposed that describes how geomorphic features of river channels create hydraulic processes, including hyporheic flows, that influence where salmon spawn in unconstrained...

Watershed councils and woodland owners : the Oregon experience

Creator:: Rickenbach, Mark G., 1968-
Abstract:: Oregon's watershed councils are local, non-regulatory, collaborative forums charged with the recovery of endangered salmon and improving water quality under The Oregon Plan for Salmon and Watersheds. Private forest landowners, given their prominence is owning riparian areas, are central to success of these efforts. Using a statewide survey of watershed...

Anthropogenic activities associated with the status of salmon stocks in Pacific Northwest watersheds

Creator:: Mrakovcich, Karina Lorenz
Abstract:: Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...

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...

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...

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....

The Influence of Scale in a Structured Decision Making Framework for Chinook Salmon Management

Creator:: McDonnell, Kevin N.
Abstract:: The goal of my dissertation was to explore how scale influences stream restoration prioritization strategies for an anadromous species and identify influential uncertainties that exist at different scales. My objectives were to (1) produce a comprehensive review of the Chinook salmon management challenges in California’s Central Valley and identify the...
