In addition to standard spawning surveys for coho salmon, this report contains additional sampling in the Yaquina River, at the Salmon River Hatchery and tributaries of Coos Bay "to document straying of private hatchery coho salmon from the Oregon Aqua-Foods (OAF) facility at South Beach, Yaquina Bay, and Anadromous, Inc.,...
Natural and gabion modified habitats containing coho salmon
(Oncorhynchus kisutch) were observed and measured seasonally in East
Fork Lobster Creek, a fifth order stream in western Oregon. Coho
salmon usually inhabited backwater and secondary channel pools in
winter. Large wood debris complexes and undercut banks were the
primary sources of...
In spite of the progressive restrictions of the commercial river fishery during the past fifty years, the trend of the salmon populations of the coastal rivers has been downward. It is almost impossible to isolate and analyze separately the causes of this decline, and any attempt to saddle one factor...
An apparent increase in the survival rate of experimental groups of coho salmon was demonstrated after two generations of selective breeding. Recoveries of 2-year-old coho were obtained from experimental groups of interstock and intrastock parent crosses.

The Troll Salmon Investigation is responsible for obtaining fishery and biological data, analyzing these data, and recommending appropriate management options for the troll fishery. Proposed management options are designed to achieve the optimum use of the salmon resource on a sustained basis. Activities pursued during FY 1977 included the sampling...
Estuarine residence and growth of juvenile chum salmon
(Oncorhynchus keta) from Netarts Bay, Oregon were estimated
from daily-formed growth increments of sagittal otoliths
which are distinguishable from accretion patterns formed
during freshwater residence. Estuarine residence time was
inversely related to the average size at which juvenile chum
salmon entered Netarts...

The Independent Multidisciplinary Science Team (IMST) was directed to evaluate the extent of predatory impacts of marine mammals and seabirds on salmonids and to recommend actions to mitigate impacts. IMST focused on the Oregon Department of Fisheries and Wildlife Action Plans because they provide the programmatic direction for the State...
This volume of the PMFC bulletin focuses on salmon troll fisheries, with descriptions of the California and Oregon fisheries as well as a research report on the Washington State troll fishery.
Fish Commission of Oregon personnel seined selected locations of Tillamook Bay, Oregon, from June to September 1972, to determine if juvenile salmon were rearing in the estuary and to get some concept of relative numbers of fish in the various parts of the bay. These data then could be compared...
This is the first report on the Independent Multidisciplinary Science Team’s (IMST) review of the hatchery-related measures in the Oregon Plan for Salmon and Watersheds (Oregon Plan). This report focuses on the consistency of the Oregon Plan with issues common to the findings of three independent scientific panels regarding hatchery...
This report on departmental activities describes "physical stream and lake surveys, spawning fish surveys and individual investigations of particular human activities which might affect the well being of the salmon resource. The advent of federal cooperation has allowed an expansion of activities to include intensive collection of data on streams...
