different prevalences of renibacterium salmoninarum detected by elisa in alaskan chinook salmon oncorhynchus tshawytscha spawned from freshwater and seawater.	soluble antigen of renibacterium salmoninarum (rs) was detected by a polyclonal enzyme-linked immunosorbent assay (elisa) at significantly higher prevalences in adult chinook salmon oncorhynchus tshawytscha that matured in freshwater than in the same cohort of fish spawned after maturation in seawater. the cumulative results were consistent during 4 yr of comparison at the little port walter hatchery on baranof island, alaska, usa. possible causes for this difference are discussed. maturation of ...	1999	10092972
pcbs, pcdd/fs, and organochlorine pesticides in farmed atlantic salmon from maine, eastern canada, and norway, and wild salmon from alaska.	farmed atlantic salmon (salmo salar) from maine and eastern canada, wild alaskan chinook salmon (oncorhynchus tshawytscha), and organically farmed norwegian salmon samples were analyzed for the presence of polychlorinated biphenyls (pcbs), dioxin-like pcbs, polychlorinated dibenzo-p-dioxins (pcdds), dibenzo-p-furans (pcdfs), and chlorinated pesticides. pcdd and pcdf congeners were not detected in > 80% of the samples analyzed. total pcb concentrations (7.2-29.5 ng/g, wet weight, ww) in the farme ...	2006	16999109
first report of erythrocytic inclusion body syndrome (eibs) in chinook salmon oncorhynchus tshawytscha in alaska, usa.	juvenile seawater-reared chinook salmon oncorhynchus tshawytscha at a hatchery on baranoff island, alaska, usa, sustained chronic mortality associated with anemia and mixed infections by various obligate and opportunistic pathogens including a cytoplasmic erythrocytic virus resembling the agent of erythrocytic inclusion body syndrome (eibs). this is the first case report of eibs in alaska and is a range extension of the disease.	2007	17760390
residues of pbdes in northeastern pacific marine fish: evidence for spatial and temporal trends.	in the flesh (skinless fillet) of chinook, chum, coho, pink, and sockeye salmon (oncorhynchus tshawytscha, o. keta, o. kisutch, o. gorbuscha, and o. nerka, respectively), sablefish (anoplopoma fimbria) and walleye pollock (theragra chalcogramma) from several sites in the northeast pacific sampled between 2002 and 2008, tetra- and pentabrominated diphenyl ethers (bdes) (bde 47, 49, 99, and 100) dominated the congener distribution. chinook and sablefish contained the highest concentrations, follow ...	2011	21360729
genetic differentiation of alaska chinook salmon: the missing link for migratory studies.	most information about chinook salmon genetic diversity and life history originates from studies from the west coast usa, western canada and southeast alaska; less is known about chinook salmon from western and southcentral alaska drainages. populations in this large area are genetically distinct from populations to the south and represent an evolutionary legacy of unique genetic, phenotypic and life history diversity. more genetic information is necessary to advance mixed stock analysis applica ...	2011	21429177
self-sustaining populations, population sinks or aggregates of strays: chum (oncorhynchus keta) and chinook salmon (oncorhynchus tshawytscha) in the wood river system, alaska.	small populations can provide insights into ecological and evolutionary aspects of species distributions over space and time. in the wood river system in alaska, usa, small aggregates of chinook (oncorhynchus tshawytscha) and chum salmon (o. keta) spawn in an area dominated by sockeye salmon (o. nerka). our objective was to determine whether these chinook and chum salmon are reproductively isolated, self-sustaining populations, population sinks that produce returning adults but receive immigrati ...	2011	22026559
ichthyophonus-infected walleye pollock theragra chalcogramma (pallas) in the eastern bering sea: a potential reservoir of infections in the north pacific.	in 2003, the alaska walleye pollock industry reported product quality issues attributed to an unspecified parasite in fish muscle. using molecular and histological methods, we identified the parasite in bering sea pollock as ichthyophonus. infected pollock were identified throughout the study area, and prevalence was greater in adults than in juveniles. this study not only provides the first documented report of ichthyophonus in any fish species captured in the bering sea, but also reveals that ...	2014	23941303
