An examination of differential survival in downstream migrating coho salmon smolts
The smolt stage of the life history of Pacific salmon (Onchorhynchus sp.) has received little attention relative to the other life history stages. I examined mortality during the downstream migration of coho salmon (0. kisutch) smolts by trapping and marking smolts high in the watershed and …

Recovery of Oregon Coast Coho Salmon (Onchorhynchus kitsutch) through Restoration of Freshwater Habitats
<p>Pacific salmon populations are significantly lower than historic levels on the Western Coast of the United States. The Oregon Coast coho salmon Evolutionary Significant Unit (ESU) was listed as threatened under the Endangered Species Act in February 2008. The total number of adult coho salmon …

Corticosteroid receptor dynamics and smolting in hatchery-reared and wild coho salmon (Oncorhynchus kisutch)
… in corticosteroid receptors (CR) in the gills of coho salmon (Oncorhynchus kisutch) were examined to determine what effect smolting and rearing environment had on gill tissue sensitivity to cortisol. CR concentration and affinity were found to change seasonally with the increases in gill …

Impacts of sedimentation on early-life phenotypes and gene expression in coho salmon (Oncorhynchus kisutch)
… on phenotypic outcomes and gene expression in coho salmon (Oncorhynchus kisutch). I obtained O. kisutch eggs from the Sugsaw Hatchery located on Vancouver Island, BC, and reared them in one of three substrate (0% fine sediment, 10% fine sediment, 20% fine sediment) or one of two no substrate …

Detecting Change in Central California Coast Coho Salmon Habitat in Scotts Creek, California, from 1997–2013
… supports the southernmost extant population of Coho Salmon (<em>Oncorhynchus kisutch</em>) in North America. In 1997, the California Department of Fish and Game (now Fish and Wildlife) conducted an extensive habitat typing survey of mainstem Scotts Creek, describing all habitat units from the …

Influence of Early Life Stage Hatchery Enhancement Practices on Maternal Reproductive Investment in Coho Salmon (Oncorhynchus kisutch)
… are a central component of Canadian Pacific salmon management, supporting commercial, recreational, cultural, and conservation objectives. However, the consequences of captive rearing environments for the reproductive phenotype of returning adults remain poorly understood. In salmonids, …

Chemical, Physical and Sensorial Compositions of Farmed and Wild Yellow Perch (Perca flavescens), Southern Flounder (Paralichthys lethostigma) and Coho Salmon (Oncorhynchus kisutch)
… Wild, farmed and growth-enhanced transgenic coho salmon (market-size) were compared, regarding their body composition and nutritional value. All treatments showed highest lipid levels in the ventral frontal sections and lowest in the tail (p ≤ 0.05). Overall wild fish showed lower lipid …

Lepeophtheirus salmonis, parasitizing three species of pacific salmon (Oncorhynchus spp.): host variations in load, morphology, fecundity, and genetics of the salmon louse
… study is to determine biological parameters of salmon lice (Lepeophtheirus salmonis) as they parasitize different species of Pacific Ocean salmonids off the north Pacific coast of Washington State. Parasite load counts of L. salmonis were made and individuals were collected from salmonids in …

Resource use and life history patterns of juvenile Coho and Chinook salmon in an Alaskan estuary
… valuable nursery grounds for anadromous Pacific salmon supplying diverse habitats, quality foraging grounds, and a transition between freshwater and saltwater environments. By providing alternative rearing habitats, estuaries may also bolster the life history diversity expressed in a population, …

Spatial dynamic groundwater regulation to ensure adequate instream flows for salmon
… irrigation by farmers has harmed the local coho salmon species by reducing the natural flows of stream habitats. The coho salmon have been listed as Threatened under the state and federal Endangered Species Acts, and therefore must be protected. The results indicate that wells located …

DIET ANALYSIS OF NATIVE AND NON-NATIVE JUVENILE SALMONIDS IN A LAKE SUPERIOR TRIBUTARY
<p>Introductions of Pacific salmonids to the Great Lakes and their tributaries have caused concerns about potential competition with native brook trout (<em>Salvelinus fontinalis</em>) of the region. My research evaluated the diet of five fish size categories (FSCs) of brook trout, non-native …

Impacts to Anadromous Fish through Groundwater Extraction
… aquifer in Northern California and impacts to coho salmon (Oncorhynchus kisutch) within a shallow, mostly unconfined alluvial aquifer. Section three studies the Cosumnes River aquifer in the Central Valley and impacts to fall-run Chinook salmon (Oncorhynchus tschawytscha) within a deep alluvial …

Influence of physical and biological habitat variables on juvenile salmonid and invertebrate drift abundance in southwest British Columbia streams
… that influence the abundance of juvenile salmonids in British Columbia streams will improve management practices. Habitat models are tools that provide insight into organisms’ habitat needs and provide a more efficient mechanism for estimating population abundance than direct measurement. …

Factors influencing infectious agent communities and infection burden in free-ranging migratory adult salmonids across Canada
… culturally, and economically important salmonid species to characterize biological and environmental factors that mediate host response and survival associated with relative infection burden (RIB). To achieve this goal, a synthesis of the current state of wild fish epidemiology was …

Lower Scotts Creek Floodplain and Habitat Enhancement Project
… population of Central California Coast (CCC) Coho Salmon (endangered) in addition to CCC steelhead (threatened). Fisheries biologists believe overwinter mortality due to lack of refuge habitat is the primary factor limiting salmonid production. Instream rearing habitat may also be limiting, …
