This document summarizes the 1966-67 winter steelhead fisheries on the Alsea and Wilson Rivers, and describes the effects of the three-fish bag limit on total harvest on the Wilson River.
This report the sizes for winter steelhead runs of the Willamette River and many of its tributaries from 1958-69, giving numbers and suggesting possible reasons for small runs.
Results of the first year of the Deschutes summer steelhead ecology and hatchery assessment. “This report covers the first year of a study of Deschutes summer steelhead ecology and factors limiting efficiency of hatchery production of summer steelhead smolts” (Contents).
This document contains a result of a study to determine the role of hatchery-reared winter steelhead in steelhead fisheries. The study examines the contribution of these salmon ‘with respect to’ angling intensity, number of fish stocked, contribution of native stocks, and several other factors. It also investigates survival of hatchery-reared...
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....
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...
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
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)
Trapping migrating steelhead trout smolts was done in the spring and early summers of 1991 and 1992 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)
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...
