Ecological relation of sympatric steelhead and resident rainbow trout in the Deschutes River, Oregon

Creator:: Zimmerman, Christian E.
Abstract:: Sympatric steelhead and resident rainbow trout (Oncorhynchus mykiss) are known to exist in many rivers throughout the Pacific Rim. Whether sympatric steelhead and resident rainbow trout are polymorphisms within a single gene pool or two reproductively isolated populations has significant implications concerning the study and conservation of this polytypic species....

1993 Calf Creek migrant trapping results and juvenile steelhead (Oncorhynchus mykiss) emigration estimate

Creator:: Harkleroad, Glenn R.
Abstract:: Trapping migrating steelhead trout smolts was done in the spring and early summer of 1993 as part of the 1990 Umpqua National Forest Land and Resource Management Plan. Calf Creek was monitored to "validate smolt output estimates" and to "determine if changes in habitat quality are occurring." (Introduction)

Survival and behavior of juvenile steelhead trout (Oncorhynchus mykiss) in two small estuaries in Oregon

Creator:: Romer, Jeremy D.
Abstract:: A number of steelhead (Oncorhynchus mykiss) populations are at risk throughout Oregon, including five populations that are federally listed as threatened or endangered. However, little is known about behavior and survival of these fish as they transition from freshwater to seawater. We investigated whether estuarine survival varies on a temporal...

Reconnecting aquatic habitats : validating historical habitat use by anadromous fishes using telemetry and stable isotope analysis above barriers

Creator:: Lewis, Sierra Koch
Abstract:: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My...

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...

Siletz River summer steelhead study

Creator:: Weber, Walter G., Fortune, John D., Jr, and Oregon. Wildlife Commission
Abstract:: "The Siletz River ... is the only short coastal stream in Oregon inhabited by a run of what are generally thought to be native summer steelhead. Hatchery-reared progeny from Siletz River stock have been released into and have become established in two other Oregon coastal streams, the Nestucca and Wilson...

Description and prediction of broad-scale spatial variability in expression of anadromy in female Oncorhynchus mykiss in the John Day River, Oregon, USA

Creator:: Mills, Justin S.
Abstract:: Partial migration is a common migratory behavior where some individuals in a population migrate and others do not. Patterns of partial migration can vary dramatically, especially for species that inhabit a wide range of environments. I described and predicted spatial variation in marine migration (anadromy) of female Oncorhynchus mykiss (steelhead...
