qPCR data for northern pike eDNA surveys in Lake Roosevelt, Washington, 2022 qPCR data for northern pike eDNA surveys in Lake Roosevelt, Washington, 2022
The data support a study that surveyed the spatial and seasonal variability of northern pike (Esox lucius) environmental DNA (eDNA) between river kilometer 1103 and 1158 in Lake Roosevelt, Washington, USA. The metadata represent qPCR quantification cycle (Cq) values for a northern pike assay performed on water samples collected at the same locations in June and September 2022, water...
Acoustic-tagged juvenile Chinook salmon (Oncorhynchus tshawytscha) detections in Lookout Point Reservoir and downstream in the Middle Fork Willamette River, Oregon, 2024-25 Acoustic-tagged juvenile Chinook salmon (Oncorhynchus tshawytscha) detections in Lookout Point Reservoir and downstream in the Middle Fork Willamette River, Oregon, 2024-25
Federally-threatened ago-0 spring Chinook salmon (Oncorhynchus tshawytscha) were acoustic tagged and released near Lookout Point Reservoir to estimate passage and survival during the second year of an experimental reservoir drawdown operation that was designed to facilitate downstream passage through two reservoirs and dams. The experimental operation consisted of lowering the water...
Status and trends of adult Lost River (Deltistes luxatus) and shortnose (Chasmistes brevirostris) sucker populations in Upper Klamath Lake, Oregon, 2025 (ver. 3.0, July 2025) Status and trends of adult Lost River (Deltistes luxatus) and shortnose (Chasmistes brevirostris) sucker populations in Upper Klamath Lake, Oregon, 2025 (ver. 3.0, July 2025)
Data were collected as part of a long-term capture-recapture program to assess the population dynamics of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder (PIT) tags during their spawning...
Surveillance for nervous necrosis virus in black sea bass from the U.S. Atlantic coast Surveillance for nervous necrosis virus in black sea bass from the U.S. Atlantic coast
Viral nervous necrosis is a neurologic disease that causes vacuolating lesions in the brain and retina of a broad range of marine fish species. The viral agent responsible is nervous necrosis virus (NNV), a Betanodavirus within the family Nodaviridae. Based on genetic characterization of the viral genome, at least four species of NNV are known to exist, though this diversity is likely...
Acoustic-tagged juvenile Chinook salmon (Oncorhynchus tshawytscha), steelhead (O. mykiss), and sockeye salmon (O. nerka) detections in the Yakima River, Washington, 2018-2024 (version 1.1, September 2025) Acoustic-tagged juvenile Chinook salmon (Oncorhynchus tshawytscha), steelhead (O. mykiss), and sockeye salmon (O. nerka) detections in the Yakima River, Washington, 2018-2024 (version 1.1, September 2025)
Juvenile Chinook salmon (age 0 and age 1), steelhead, and sockeye salmon were tagged with acoustic transmitters and released at sites along the Yakima River in and below Yakima, WA from 2018 to 2024. Detection sites varied across years but included arrays placed at diversion dams, canals, hydropower facilities, and other locations throughout the Yakima and Columbia rivers. Study design...
Cyanobacteria, other water-quality, and discharge data collected from the Raritan River Basin, New Jersey, August 2020 through August 2021 Cyanobacteria, other water-quality, and discharge data collected from the Raritan River Basin, New Jersey, August 2020 through August 2021
Within New Jersey’s Raritan Basin Water Supply Complex, multiple lakes and reservoirs with persistent and recurrent cyanobacterial harmful algal blooms (cyanoHABs) discharge water which ultimately travels downstream in surface water to drinking-water intakes. Cyanobacteria and other water-quality data were collected as part of a collaborative study among multiple agencies, including the...
