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...

White sturgeon (Acipenser transmontanus) passage at the Dalles Dam, Columbia River, USA White sturgeon (Acipenser transmontanus) passage at the Dalles Dam, Columbia River, USA
White sturgeon (Acipenser transmontanus) ???95 cm TL were monitored using acoustic and radio telemetry at a large hydroelectric dam (the Dalles Dam) on the Columbia River, during March 2004 through November 2005 to determine timing and routes of passage and to characterize general movements. Transmitters were surgically implanted into 148 fish during the study; 90 were released into the...

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...

Behavior of White Sturgeon near hydroprojects and fishways Behavior of White Sturgeon near hydroprojects and fishways
During March 2004 through November 2005, white sturgeon movements were monitored at The Dalles Dam to characterize their distribution and movements in the immediate vicinity of the dam and to determine timing and routes of passage. A combination of radio and acoustic telemetry technologies were used to detect tagged fish within fishways and at strategic locations along the dam, the...

Survival estimates of migrant juvenile salmonids through Bonneville Dam using radio telemetry, 2005 Survival estimates of migrant juvenile salmonids through Bonneville Dam using radio telemetry, 2005
During 2005, we evaluated the survival of radio-tagged yearling and subyearling Chinook salmon and steelhead trout through the Bonneville Dam spillway, powerhouses 1 and 2, the corner collector and juvenile bypass system (JBS) at powerhouse 2, and through all routes collectively using the route-specific survival model. Radio-tagged fish were released at The Dalles Dam and in the tailrace...
