A fish survey of the White River, Nevada A fish survey of the White River, Nevada

In spring and summer 1991 and 1992, we surveyed fishes of the White River system, Nye and White Pine Counties, Nevada, to determine the status of natives. There are 5 known native fishes to the White River: Lepidomeda albivallis (White River spinedace), Crenichthys baileyi albivallis (Preston White River springfish), Crenichthys baileyi thermophilus (Moorman White River springfish)...

Spatial partitioning and asymmetric hybridization among sympatric coastal steelhead trout (Oncorhynchus mykiss irideus), coastal cutthroat trout (O. clarki clarki) and interspecific hybrids Spatial partitioning and asymmetric hybridization among sympatric coastal steelhead trout (Oncorhynchus mykiss irideus), coastal cutthroat trout (O. clarki clarki) and interspecific hybrids

Hybridization between sympatric species provides unique opportunities to examine the contrast between mechanisms that promote hybridization and maintain species integrity. We surveyed hybridization between sympatric coastal steelhead (Oncorhynchus mykiss irideus) and coastal cutthroat trout (O. clarki clarki) from two streams in Washington State, Olsen Creek (256 individuals sampled) and...

Imaging fall Chinook salmon redds in the Columbia River with a dual-frequency identification sonar Imaging fall Chinook salmon redds in the Columbia River with a dual-frequency identification sonar

We tested the efficacy of a dual-frequency identification sonar (DIDSON) for imaging and enumeration of fall Chinook salmon Oncorhynchus tshawytscha redds in a spawning area below Bonneville Dam on the Columbia River. The DIDSON uses sound to form near-video-quality images and has the advantages of imaging in zero-visibility water and possessing a greater detection range and field of...

Molecular characterization of birnaviruses isolated from wild marine fishes at the Flemish Cap (Newfoundland) Molecular characterization of birnaviruses isolated from wild marine fishes at the Flemish Cap (Newfoundland)

Several isolates of aquatic birnaviruses were recovered from different species of wild fish caught in the Flemish Cap, a Newfoundland fishery close to the Atlantic coast of Canada. The nucleotide sequence of a region of the NS gene was identical among the isolates and was most similar to the Dry Mills and West Buxton reference strains of infectious pancreatic necrosis virus (IPNV)...

White sturgeon mitigation and restoration in the Columbia and Snake rivers upstream from Bonneville Dam, Annual progress report April 2002 - March 2003. Report C White sturgeon mitigation and restoration in the Columbia and Snake rivers upstream from Bonneville Dam, Annual progress report April 2002 - March 2003. Report C

During 1 April 2002 through 31 March 2003, the U.S. Geological Survey (USGS) continued work on several tasks, including quantifying habitat suitable for white sturgeon Acipenser transmontanus spawning, a long-term survey of young-of-the-year (YOY) white sturgeon recruitment in the lower Columbia River, and a laboratory study investigating predation on larval and juvenile white sturgeon...

Cloning, expression, cellular distribution, and role in chemotaxis of a C5a receptor in rainbow trout: The first identification of a C5a receptor in a nonmammalian species Cloning, expression, cellular distribution, and role in chemotaxis of a C5a receptor in rainbow trout: The first identification of a C5a receptor in a nonmammalian species

C3a, C4a, and C5a anaphylatoxins generated during complement activation play a key role in inflammation. C5a is the most potent of the three anaphylatoxins in eliciting biological responses. The effects of C5a are mediated by its binding to C5a receptor (C5aR, CD88). To date, C5aR has only been identified and cloned in mammalian species, and its evolutionary history remains ill-defined...

Bi-parentally inherited species-specific markers identify hybridization between rainbow trout and cutthroat trout subspecies Bi-parentally inherited species-specific markers identify hybridization between rainbow trout and cutthroat trout subspecies

Eight polymerase chain reaction primer sets amplifying bi-parentally inherited species-specific markers were developed that differentiate between rainbow trout (Oncorhynchus mykiss) and various cutthroat trout (O. clarki) subspecies. The primers were tested within known F1 and first generation hybrid backcrosses and were shown to amplify codominantly within hybrids. Heterozygous...
