We evaluated the effectiveness of using hatchery coho salmon Oncorhynchus kisutch presmolts to rebuild wild populations in Oregon coastal streams. Juvenile and adult populations were monitored in 15 stocked and 15 unstacked streams from summer 1980 until summer 1985. During the summers following the planting of presmolts, the number of...
Gives standard spawning data for salmon in Oregon and adds information "to document straying of private hatchery coho salmon from Oregon Aqua-Foods'(OAF) facility at Yaquina Bay. . . The program was conducted in response to concerns by fisheries managers and the public on the possible long-term effects of interbreeding wild...
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...
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...
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...
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...
This report describes private Chinook, chum and coho hatcheries in Oregon in the mid-1980s. It includes a map of hatchery locations, statistical tables, and a section discussing opposition to private salmon hatcheries (PSHs). "In this report I will discuss the development of the PSH regulations, status of current permits, permits...
Reports on private Chinook, chum and coho salmon hatcheries (PSHs)in Oregon in the mid-1980s. Includes a map of hatchery operation sites, and statistical tables. Oregon State University's facility at Whiskey Creek, Netarts Bay, was back in operation. Suspected impacts of a private hatchery on the run of coho salmon on...
Describes private Chinook, chum and coho salmon hatcheries in Oregon in the early 1980s. Map, statistical tables. "As hatchery diets and rearing techniques improved in recent years, private citizens again became interested in propagating salmon. Research at 0regon State University (OSU)in hatching chum salmon using inexpensive streamside incubators increased public...
This report describes private Chinook, chum and coho hatcheries in Oregon. It includes a map of hatchery locations, statistics, and a discussion of issues associated with straying of hatchery salmon. "This report summarizes information on development, monitoring, evaluation, and gives production and return information for 1983." (from the Introduction)
Reports on private Chinook, chum and coho salmon hatcheries in Oregon. Includes statistics and a map showing hatchery locations. "This report provides information on developments, shows progress in 1982, and summarizes production and return information." (from the Introduction)
Provides information on private Chinook, chum and coho salmon hatcheries in Oregon. Includes statistics and a map showing hatchery locations. Mentions the end of Oregon State University's involvement with the Whiskey Creek hatchery in Netarts Bay. "This report provides information on recent developments, progress in 1981, with summaries of production...
This document gives information on private Chinook, chum and coho hatcheries in Oregon in the late 1970s. Includes statistics and a map of hatchery sites. "This review of private hatchery development includes some discussion on the limitations and problems pertinent to continued development." (from the Introduction)
Describes private Chinook, chum and coho hatcheries in Oregon. Includes map, b+w photographs, statistics. "This review of developments in Oregon's private salmon industry includes information on experimental development, progress of private permit holders, and current regulations governing private salmon hatchery operations in Oregon. A brief review of Oregon State University's...
Understanding the origin and nature of intra specific biodiversity enables us to better conserve and manage animal populations. Biological diversity is seen at different scales and for different traits such as behavior, morphology, physiology, and life history. Behavior is especially important since behavioral changes are believed to precede changes in...
Private hatchery operations continued in 1973 and 1974 on more of an experimental than production basis. For 1973-brood chums, OSU increased their production at Whiskey Creek to a release of 761,000 fry and the state sold 247,500 eggs to private operators. AduIt returns to Whiskey Creek in 1973 were encouraging...
Reports on potential sites for a salmon hatchery on the Yaquina River. "Each tributary has been carefully studied and special attention given to those creeks on which possible hatchery sites were found. Items given consideration on each stream were: pond site locations, flow of water, drop of stream bed, nature...
Under July 1, 1972 - June 30, 1973 cost levels for the Little White Salmon and Willard National Fish Hatcheries, small budget reductions made by reducing expenditures for fish food resulted in sharp increases in average total cost per pound of salmon produced.
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...
