Chemical contaminants in fish feeds used in federal salmonid hatcheries in the USA Chemical contaminants in fish feeds used in federal salmonid hatcheries in the USA
Recent studies have demonstrated that fish feeds contain significant concentrations of contaminants, many of which can bioaccumulate and bioconcentrate in fish. Organochlorine (OC) contaminants are present in the fish oils and fish meals used in feed manufacture, and some researchers speculate that all fish feeds contain measurable levels of some contaminants. To determine the...

Genotyping of Korean isolates of infectious hematopoietic necrosis virus (IHNV) based on the glycoprotein gene Genotyping of Korean isolates of infectious hematopoietic necrosis virus (IHNV) based on the glycoprotein gene
Glycoprotein (G) gene nucleotide sequences of four Korean isolates of infectious hematopoietic necrosis virus (IHNV) were analyzed to evaluate their genetic relatedness to worldwide isolates. All Korean isolates were closely related to Japanese isolates of genogroup JRt rather than to those of North American and European genogroups. It is believed that Korean IHNV has been most likely...

Evolutionary history of the ABCB2 genomic region in teleosts Evolutionary history of the ABCB2 genomic region in teleosts
Gene duplication, silencing and translocation have all been implicated in shaping the unique genomic architecture of the teleost MH regions. Previously, we demonstrated that trout possess five unlinked regions encoding MH genes. One of these regions harbors ABCB2 which in all other vertebrate classes is found in the MHC class II region. In this study, we sequenced a BAC contig for the...

Developing methods to assess and predict the population level effects of environmental contaminants. Developing methods to assess and predict the population level effects of environmental contaminants.
The field of ecological toxicity seems largely to have drifted away from what its title implies--assessing and predicting the ecological consequences of environmental contaminants--moving instead toward an emphasis on individual effects and physiologic case studies. This paper elucidates how a relatively new ecological methodology, interaction assessment (INTASS), could be useful in...

Coastal habitats in Puget Sound: A research plan in support of the Puget Sound Nearshore Partnership Coastal habitats in Puget Sound: A research plan in support of the Puget Sound Nearshore Partnership
The purpose of this research plan is to identify high-priority research goals and objectives and delineate the critical questions and information gaps that need to be addressed to provide natural-resource managers and policy- and decisionmakers with tools to effectively undertake restoration planning and adaptive management of the nearshore ecosystems of Puget Sound.

Science for maintaining riverine ecosystems: Actions for the USGS identified in the workshop "Analysis of Flow and Habitat for Aquatic Communities" Science for maintaining riverine ecosystems: Actions for the USGS identified in the workshop "Analysis of Flow and Habitat for Aquatic Communities"
Federal and state agencies need improved scientific analysis to support riverine ecosystem management. The ability of the USGS to integrate geologic, hydrologic, chemical, geographic, and biological data into new tools and models provides unparalleled opportunities to translate the best riverine science into useful approaches and usable information to address issues faced by river...

Survival estimates of migrant juvenile Salmonids through Bonneville Dam using radio telemetry, 2004 Survival estimates of migrant juvenile Salmonids through Bonneville Dam using radio telemetry, 2004
During 2004, the USGS evaluated the survival of radio-tagged yearling and subyearling Chinook salmon and steelhead trout through the ice and trash sluiceway and the minimum gap runner (MGR) turbine unit at Bonneville Dam’s powerhouse 1. Survival was estimated using paired release-recapture models with paired releases made directly into these passage routes and in the tailrace of...

Range expansion of an exotic Siberian prawn to the Lower Snake River Range expansion of an exotic Siberian prawn to the Lower Snake River
The introduction of non-native plant and animal species in aquatic systems is of increasing concern because of their potentially negative ecological and economic impacts (Sytsma et al. 2004). There are many examples of food web repercussions resulting from non-native invertebrate introductions. For example, in Flathead Lake, Montana, the kokanee salmon (Oncorhynchus nerka) population...
