A Bayesian network for prioritizing restoration of aquatic connectivity

Creator:: Andersen, Eric J.
Abstract:: Re-establishing connectivity is a primary restoration activity for enhancing the recovery of migratory fishes, but actions are often limited by lack of funds and understanding of the benefits of individual projects. The objective of this study was to develop a Bayesian Network (BN) to assess priorities for restoration of aquatic...

Assessing disease impacts of hatcheries on downstream salmonids in the Willamette River Basin, Oregon

Creator:: Jakaitis, Michelle
Abstract:: Hatcheries are often perceived as a source of pathogen amplification, potentially increasing disease risk to free-ranging populations; at the same time, free-ranging fishes may introduce pathogens into hatcheries through untreated water sources. Many pathogens exist naturally within the environment (with the exception of introduced pathogens) and the presence of a...

Basin-scale variation in the spatial pattern of fall movement of juvenile coho salmon in the West Fork Smith River, Oregon

Creator:: Hance, Dalton J.
Abstract:: from the summer dry season to the winter wet season. Such movement that connects summer and winter habitats may be particularly important for coho salmon, O. kisutch, because availability of overwintering habitat can limit freshwater survival for this species. Here, I describe basin-scale variability in the spatial pattern of fall...

Born to run? Integrating individual behavior, physiology, and life histories in partially migratory steelhead and rainbow trout (Oncorhynchus mykiss)

Creator:: Sloat, Matthew R.
Abstract:: Steelhead and rainbow trout are common names for marine-migratory (anadromous) and freshwater-resident forms of Oncorhynchus mykiss, a partially migratory salmonid fish. Anadromous and resident forms are sympatric and can produce offspring with a life history different from their own (i.e., steelhead parents can produce rainbow trout offspring and vice versa)....

Breeding site selection by coho salmon (Oncorhynchus kisutch) in relation to large wood additions and factors that drive reproductive success

Creator:: Clark, Steven
Abstract:: The fitness of female Pacific salmon (Oncorhynchus spp.) with respect to breeding behavior can be partitioned into at least four components: survival to reproduction, competition for breeding sites, success of egg incubation, and suitability of the local environment near breeding sites for early rearing of juveniles. Accordingly, breeding sites should...

Climate warming effects on the life cycle of the parasite Ceratomyxa shasta in salmon of the Pacific Northwest

Creator:: Chiaramonte, Luciano V.
Abstract:: Aquatic ecosystems continue to be increasingly affected by climate warming. For salmonids in the Pacific Northwest of North America, increasing temperatures pose tighter thermal constraints on their habitat use as well as aspects of their individual performance, such as disease resistance. This thesis examines the effect of temperature on the...

Connecting Tidal-fluvial Life Histories to Survival of McKenzie River Spring Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Rose, Gordon W.
Abstract:: Chinook salmon returns to the Columbia River basin have declined due to impacts of a growing human population, despite significant mitigation expenditures. Consequently, fisheries managers have become focused on recovery and long-term viability of at-risk populations. A viable population depends, in part, on the connectivity and quality of diverse habitat...

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...

Cool, pathogen free refuge lowers pathogen associated prespawn mortality of Willamette River Chinook salmon (Oncorhynchus tshawytscha)

Creator:: Benda, Susan
Abstract:: Spring Chinook salmon, Oncorhynchus tshawytscha, are transported above dams in the Willamette River to provide access to blocked spawning habitat. However, 30-95% of these transplants may die before spawning in some years. To varying degrees, salmon in other tributaries--both blocked and unblocked--have similar prespawn mortality (PSM). Our study determined if...

Distribution and coinfection of microparasites and macroparasites in juvenile salmonids in three upper Willamette River tributaries

Creator:: Roon, Sean Robert
Abstract:: Wild fish populations are typically infected with a variety of micro- and macroparasites that may affect fitness and survival, however, there is little published information on parasite distribution in wild juvenile salmonids in three upper tributaries of the Willamette River, OR. The objectives of this survey were to document (1)...
