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....

Development of a progeny marker for steelhead

Creator:: Shippentower, Gene E.
Abstract:: This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...

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...

Cormorant harassment to protect juvenile salmonids in Tillamook County, Oregon

Creator:: Bayer, Range D., 1947-
Abstract:: The goal of the Oregon Plan is to restore wild coho and wild steelhead runs. Under the federal Endangered Species Act, wild coho salmon along the Oregon Coast are listed as Threatened and wild Oregon Coast steelhead are a candidate for listing. Although cormorants have been hazed at the Nehalem...

The Oregon Plan for Salmon and Watersheds : biennial report 2001-2003

Creator:: Oregon Watershed Enhancement Board
Abstract:: This is the fourth report on the Oregon Plan for Salmon and Watersheds. The first three reports focused on people – their stories and their efforts to restore watershed health and recover listed fish species. While these earlier reports contained what little information was available regarding the quantitative aspects of...

Seasonal life history of Oncorhynchus mykiss in the South Fork John Day River Basin, Oregon

Creator:: Tattam, Ian A.
Abstract:: Understanding seasonal changes in growth, survival, and movement rates is crucial to salmonid management. These life history characteristics provide a context for evaluation of management actions. We evaluated the life history of individually marked Oncorhynchus mykiss gairdneri in the South Fork John Day River basin in Northeastern Oregon. This thesis...

Managing adult hatchery summer steelhead for a recreational fishery with reduced hatchery and wild interactions

Creator:: Schemmel, Eva M.
Abstract:: Hatcheries whose purpose is to provide for a recreational fishery must minimize impacts on wild fishes. Management to reduce hatchery and wild interactions is especially important on river systems that contain Endangered Species Act (ESA) listed species. I examined adult hatchery summer steelhead, Oncorhynchus mykiss, behavior, current management and a...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

Habitat selection of hatchery and wild juvenile salmonids in Eagle Creek Basin, Oregon

Creator:: Brignon, William R.
Abstract:: To best manage Eagle Creek National Fish Hatchery and minimize any negative impacts that the current hatchery program may be having on Endangered Species Act-listed salmonids in the Eagle Creek Basin, I determined if wild fish are being displaced from preferred habitats by hatchery salmonids Oncorhynchus spp. This thesis had...
