Nuclear inclusion X testing of Pacific Razor clams from select locations in Washington and Alaska Nuclear inclusion X testing of Pacific Razor clams from select locations in Washington and Alaska
A quantitative PCR (qPCR) assay was developed to detect nuclear inclusion X (NIX) in Pacific razor clams, and assay specificity was confirmed by chromogenic in situ hybridization (CISH). Both tests were applied to evaluate NIX infections in wild Pacific razor clams collected during spring 2019. Consistent with results from earlier histopathological assessments, qPCR and CISH indicated...
Maternal transfer of PCBs in Pacific sand lance in Puget Sound, Washington Maternal transfer of PCBs in Pacific sand lance in Puget Sound, Washington
Data included in this release are from Pacific sand lance and water, sediment and suspended particulate matter collected at two sites in Puget Sound, Washington, which were evaluated for PCB concentration. PCB congener data are stored in the U.S. Fish and Wildlife Service's Environmental Contaminant Data Management System (ECDMS), accessible through the Wildlife & Environmental...
Laboratory exposure of Chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch) and rainbow trout (O. mykiss) to a Pacific Canadian strain of piscine orthoreovirus genotype one (PRV-1) Laboratory exposure of Chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch) and rainbow trout (O. mykiss) to a Pacific Canadian strain of piscine orthoreovirus genotype one (PRV-1)
Piscine orthoreovirus genotype one (PRV-1) is the causative agent of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar L.). The virus has also been found in Pacific salmonids in western North America, raising concerns about the risk to native salmon and trout. Here, we report the results of laboratory challenges using juvenile Chinook salmon, coho...
Detection of invasive aquatic plants Myriophyllum spicatum and Egeria densa in lakes using eDNA, field and mesocosm data Detection of invasive aquatic plants Myriophyllum spicatum and Egeria densa in lakes using eDNA, field and mesocosm data
We conducted a study to test the factors related to detectability of two invasive aquatic plants (Egeria densa and Myriophyllym spicatum) using environmental DNA (eDNA), over extended periods of time, and specifically examined how plant growth stage and abundance relates to eDNA detection in semi-natural and natural conditions. This dataset is from sampling performed in summer of 2018 in...
USGS Dam Removal Science Database v4.0 USGS Dam Removal Science Database v4.0
This database is the result of an extensive literature search aimed at identifying documents relevant to the emerging field of dam removal science. In total the database contains 214 citations that contain empirical monitoring information associated with 181 different dam removals across the United States and abroad. Data includes publications through 2016 and supplemented with the U.S...
2015 environmental DNA surveys for lampreys in Chehalis River tributaries, Washington 2015 environmental DNA surveys for lampreys in Chehalis River tributaries, Washington
Columns of data representing Chehalis River tributary, sample reach locations, dates of water sampling, quantitative PCR results, and whether lamprey were sampled by electrofishing in each sample reach. ***Please note that the title of this data release used to be "Environmental DNA surveys for lampreys in Chehalis River tributaries, Washington, from 2015 and 2017," but was updated for...
Data to Support Efficacy Studies of Injectable Tulathromycin for Reduction of Vertical Transmission of Renibacterium salmoninarum in Spring Chinook Salmon (Oncorhynchus tshawytscha) Data to Support Efficacy Studies of Injectable Tulathromycin for Reduction of Vertical Transmission of Renibacterium salmoninarum in Spring Chinook Salmon (Oncorhynchus tshawytscha)
Bacterial kidney disease (BKD) caused by Renibacterium salmoninarum (Rs) occurs nearly worldwide where wild or cultured salmonid fishes are present. Control of BKD is confounded by its two modes of transmission, horizontal (fish-to-fish) and vertical (from female parent to progeny via the eggs). A highly successful BKD control strategy employed in Pacific Northwest hatcheries culturing...
Data collected in 2008-2010 to evaluate juvenile salmon and forage fish use of eelgrass on the Skagit River Delta, Washington State, USA Data collected in 2008-2010 to evaluate juvenile salmon and forage fish use of eelgrass on the Skagit River Delta, Washington State, USA
Data are abundance and body size (length) of juvenile salmon, forage fish, and other species captured with a lampara net in eelgrass and nearby unvegetated habitat on the Skagit River Delta monthly, April-September, 2008-2010, as well as vegetation status, water depth, temperature, salinity, and clarity for each fish netting event.
Influence of urbanization on the health of juvenile salmonids in Pacific Northwest perennial streams Influence of urbanization on the health of juvenile salmonids in Pacific Northwest perennial streams
Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus...
Concentrations of environmental DNA (eDNA) during sockeye salmon spawning in 2016, Hansen Creek, Alaska, USA Concentrations of environmental DNA (eDNA) during sockeye salmon spawning in 2016, Hansen Creek, Alaska, USA
This dataset contains environmental DNA (eDNA) concentrations and spawning adult abundances for sockeye salmon (Oncorhynchus nerka) in Hansen Creek, a small tributary in the Wood River watershed, southeast Alaska, USA. We took temporally- and spatially-replicated eDNA samples during the spawning period (mid-July through August), along with fish counts (live, naturally dead, and killed)...
Distribution and seasonal differences in Pacific Lamprey and Lampetra spp eDNA across 18 Puget Sound watersheds, 2014 and 2015 Distribution and seasonal differences in Pacific Lamprey and Lampetra spp eDNA across 18 Puget Sound watersheds, 2014 and 2015
These data contain all the raw results needed to support the conclusions for the final product. These data are water sampling locations (latitude and longitude), date of water sampling, quantitative PCR values for each water sample, and stream flow at USGS stream gauging stations on sampling day.
Data collected in 2008-2014 to assess nearshore subtidal community response to increased sediment load during removal of the Elwha River dams, Washington State, USA Data collected in 2008-2014 to assess nearshore subtidal community response to increased sediment load during removal of the Elwha River dams, Washington State, USA
Data are time series of substrate grain size, remotely sensed water column turbidity, and measures of abundance (e.g., density, percent cover) of the nearshore subtidal (3-17 m depth) benthic community (vegetation, invertebrates, and fish) collected before (2008-2011) and during dam removal (2012-2014).
