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...
