2012, Open-File Report 2012-1236
Data on concentrations of chloride and sodium in groundwater in New Hampshire were assembled from various State and Federal agencies and organized into a database. This report provides documentation of many assumptions and limitations of disparate data that were collected to meet wide-ranging objectives and investigates temporal and spatial trends...
Slope-Area Computation Program Graphical User Interface 1.0—A Preprocessing and Postprocessing Tool for Estimating Peak Flood Discharge Using the Slope-Area Method
D. Nathan Bradley
2012, Fact Sheet 2012-3112
The slope-area method is a technique for estimating the peak discharge of a flood after the water has receded (Dalrymple and Benson, 1967). This type of discharge estimate is called an “indirect measurement” because it relies on evidence left behind by the flood, such as high-water marks (HWMs) on trees...
Application of empirical predictive modeling using conventional and alternative fecal indicator bacteria in eastern North Carolina waters
Raul Gonzalez, Kathleen E. Conn, Joey Crosswell, Rachel Noble
2012, Water Research (46) 5871-5882
Coastal and estuarine waters are the site of intense anthropogenic influence with concomitant use for recreation and seafood harvesting. Therefore, coastal and estuarine water quality has a direct impact on human health. In eastern North Carolina (NC) there are over 240 recreational and 1025 shellfish harvesting water quality monitoring sites...
Effect of survey design and catch rate estimation on total catch estimates in Chinook salmon fisheries
Joshua L. McCormick, Michael C. Quist, Daniel J. Schill
2012, North American Journal of Fisheries Management (32) 1090-1101
Roving–roving and roving–access creel surveys are the primary techniques used to obtain information on harvest of Chinook salmon Oncorhynchus tshawytscha in Idaho sport fisheries. Once interviews are conducted using roving–roving or roving–access survey designs, mean catch rate can be estimated with the ratio-of-means (ROM) estimator, the mean-of-ratios (MOR) estimator, or...
A novel antibody-based biomarker for chronic algal toxin exposure and sub-acute neurotoxicity
Kathi A. Lefebvre, Elizabeth R. Frame, Frances Gulland, John D. Hansen, Preston S. Kendrick, Richard P. Beyer, Theo K. Bammler, Frederico M. Farin, Emma M. Hiolski, Donald R. Smith, David J. Marcinek
2012, PLoS ONE (7) e36213
The neurotoxic amino acid, domoic acid (DA), is naturally produced by marine phytoplankton and presents a significant threat to the health of marine mammals, seabirds and humans via transfer of the toxin through the foodweb. In humans, acute exposure causes a neurotoxic illness known as amnesic shellfish poisoning characterized by...

Jan Lovy, N.L. Lewis, P.K. Hershberger, W. Bennett, T.R. Meyers, K.A. Garver
2012, Veterinary Microbiology (161) 66-76
Viral hemorrhagic septicemia virus (VHSV) genotype IVa causes mass mortality in wild Pacific herring, a species of economic value, in the Northeast Pacific Ocean. Young of the year herring are particularly susceptible and can be carriers of the virus. To understand its pathogenesis, tissue and cellular tropisms of VHSV in...
Geomorphic and hydrologic study of peak-flow management on the Cedar River, Washington
Christopher S. Magirl, Andrew S. Gendaszek, Christiana R. Czuba, Christopher P. Konrad, Mathieu D. Marineau
2012, Open-File Report 2012-1240
Assessing the linkages between high-flow events, geomorphic response, and effects on stream ecology is critical to river management. High flows on the gravel-bedded Cedar River in Washington are important to the geomorphic function of the river; however, high flows can deleteriously affect salmon embryos incubating in streambed gravels. A geomorphic...

Tobias J. Kock, Theresa L. Liedtke, Dennis W. Rondorf, John D. Serl, Mike Kohn, Karin A. Bumbaco
2012, North American Journal of Fisheries Management (32) 1070-1079
A 4-year evaluation was conducted to determine the proportion of juvenile coho salmon Oncorhynchus kisutch passing Cowlitz Falls Dam, on the Cowlitz River, Washington, during winter. River and reservoir populations of coho salmon parr were monitored using radiotelemetry to determine if streamflow increases resulted in increased downstream movement and dam...

Matthew G. Mesa, Brien P. Rose, Elizabeth S. Copeland
2012, North American Journal of Fisheries Management (32) 604-612
Screens are installed at water diversion sites to reduce entrainment of fish. Recently, the Farmers Irrigation District (Oregon) developed a unique flat-plate screen (the “Farmers Screen”) that operates passively and may offer reduced installation and operating costs. To evaluate the effectiveness of this screen on fish, we conducted two separate...

Inability to demonstrate fish-to-fish transmission of Ichthyophonus from laboratory infected Pacific herring Clupea pallasii to naïve conspecifics
J.L. Gregg, C.A. Grady, C.S. Friedman, P.K. Hershberger
2012, Diseases of Aquatic Organisms (99) 139-144
The parasite Ichthyophonus is enzootic in many marine fish populations of the northern Atlantic and Pacific Oceans. Forage fishes are a likely source of infection for higher trophic level predators; however, the processes that maintain Ichthyophonus in forage fish populations (primarily clupeids) are not well understood. Lack of an identified intermediate host has led...

2012, Journal of Aquatic Animal Health (24) 195-200
Viral erythrocytic necrosis (VEN) is a condition that affects marine and anadromous fish species, including herrings and salmonids, in the Atlantic and Pacific oceans. Infection is frequently associated with severe anemia and causes episodic mortality among wild and hatchery fish when accompanied by additional stressors; VEN can be presumptively diagnosed...

L.M. Hart, Niels Lorenzen, S. E. LaPatra, C.A. Grady, S.E. Roon, J. O’Reilly, J.L. Gregg, P.K. Hershberger
2012, Journal of Fish Diseases (35) 775-779
Viral haemorrhagic septicaemia virus (VHSV) and its associated disease state, viral haemorrhagic septicaemia (VHS), is hypothesized to be a proximate factor accounting for the decline and failed recovery of Pacific herring populations in Prince William Sound, AK (Marty et al. 1998, 2003, 2010). Survivors of laboratory-induced VHSV epizootics develop resistance...
