Impacts of earlier emerging steelhead fry of hatchery origin on the social structure, distribution, and growth of wild steelhead fry

Creator:: Noble, Sandra M. (Sandra Marie)
Abstract:: Newly emerged steelhead fry (Oncorhynchus mvkiss) of hatchery and wild origins were studied in laboratory stream channels and natural streams. Objectives of the study were to determine if and how earlier emerging hatchery fry influence the emigration, realized densities, growth, habitat use, social structure, and activity patterns of localized populations...

Patterns of genetic inheritance and variation through ontogeny for hatchery and wild stocks of Chinook salmon

Creator:: Hulett, Patrick L.
Abstract:: Although differences between selective pressures in hatcheries and streams have been theorized to cause genetic divergence between hatchery and wild salmonids, evidence of this is lacking. This study was initiated to document the presence or absence of genetic change in hatchery and wild stocks by characterizing genetic traits in fish...

An evaluation of the use of coho salmon presmolts to supplement wild production in Oregon coastal streams

Creator:: Solazzi, Mario F., Nickelson, Thomas E., Johnson, Steven L., and Oregon Department of Fish and Wildlife
Abstract:: 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...

Review of the hatchery measures in the Oregon plan for salmon and watersheds. Part I: consistency of the Oregon Plan with recommendations from recent scientific review panels

Creator:: Independent Multidisciplinary Science Team (Or.)
Abstract:: 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...

Rearing density as a driver of adaptation to captivity and traits under selection by domestication in hatchery reared steelhead (Oncorhynchus mykiss)

Creator:: Thompson, Neil F.
Abstract:: Releasing hatchery reared salmon and steelhead to supplement threatened and endangered populations is a widely used conservation tool. One issue with this strategy is hatchery fish have lower reproductive fitness than wild fish when spawning in the wild. One of the drivers of fitness loss in steelhead is adaptation to...

Conservation hatcheries and supplementation strategies for recovery of wild stocks of salmonids: report of a workshop : Independent Multidisciplinary Science Team, Portland, OR, June 19-21, 2000

Creator:: Independent Multidisciplinary Science Team (Or.)
Abstract:: The Independent Multidisciplinary Science Team (IMST) convened regional leaders in hatchery management and salmon recovery on June 19-21, 2000 for a scientific workshop on Conservation Hatcheries and Supplementation Strategies for the Recovery of Wild Stocks of Salmonids. The purpose was to provide better information (a) to help the IMST with...

Transcriptomic analysis using high-throughput sequencing and DNA microarrays

Creator:: Fox, Samuel E.
Abstract:: Transcriptomics and gene expression profiling enables the elucidation of the genetic response of an organism to various environmental cues. Transcriptomics enables the deciphering of differences between two closely related organisms to the same environment and in contrast, enables the elucidation of genetic responses of the same organism to different environmental...

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...

Evaluation of Research Priorities for the Oregon Plan, 2001-2003

Creator:: Independent Multidisciplinary Science Team (Or.)
Abstract:: The Oregon Plan for Salmon and Watersheds, Technical Reports from the Independent Multidisciplinary Science Team (IMST) and numerous other documents identify an extensive array of research needed to recover depressed stocks of wild salmonids in Oregon. The limitation of such listings is that they do not prioritize the research needs,...

A phenotypic comparison of thirty-eight steelhead (Oncorhynchus mykiss) populations from coastal Oregon

Creator:: Hatch, Keith Martin
Abstract:: An aspect of the genetic structure of coastal Oregon steelhead was explored and found to gradually change in a north to south pattern for the allelic frequencies of several enzymes. Isocitrate dehydrogenase and superoxide dehydrogenase were the clearest examples of this pattern of variation. This pattern was most evident in...
