We conducted a study to evaluate the movements and habitat use of juvenile salmonids, including Chinook salmon, in the lower Columbia River Estuary near dredge spoil deposition sites. Fish tagged with JSATS 416.7 kHz acoustic transmitters for upriver dam passage and survival studies were monitored using strategically placed hydrophones throughout the navigation channel, Woody Island...

Ceratomyxosis, characterized by enteritis, enteronecrosis,and abdominal distension, is caused by the myxozoan parasite Ceratonova shasta. Ceratonova shasta is capable of infecting a range of salmonids, including Chinook salmon, often resulting in increased morbidity and mortality in infected populations. Ceratonova shasta is endemic in the Pacific Northwest, however there is limited data...

We conducted a study to examine the use of off-channel and dredge spoil habitats by migrating juvenile salmonids in the Columbia River Estuary. In addition to the equipment deployed to detect transmitters implanted in juvenile salmonids for this study, a subset of the deployed gear included 69 kHz acoustic telemetry receivers. These receivers opportunistically monitored movements of...

To assess the influence of run type and flow on the routing of juvenile Chinook salmon at the Georgiana Slough junction, we assembled a dataset of fish telemetry detections and flow data spanning a 12-year period. Fish detection data were obtained from the National Marine Fisheries Service’s Environmental Research Division’s Data Access Program (ERDDAP, 2023) and represent all four...

From 2019 to 2021, sixty age 0 herring were collected and tested for infection with viral haemorrhagic septicemia virus and viral erythrocitic necrosis virus from Port Angeles Harbor in WA, USA. This dataset describes the prevalence and intensity of infection with both pathogens. Then a series of laboratory experiments were conducted to determine how the epizootics of the two pathogens...

Pollutants present in stormwater runoff can severely degrade water quality in aquatic habitats. The tire-derived chemical 6PPD-quinone is one such pollutant present in stormwater that is known to significantly impact the survival of salmonids. 6PPD-quinone is derived from 6PPD, the primary antiozonant used to protect tire rubber from ozone attack and degradation. Alternative antiozonants...

The dataset supports studies performed in Washington state in 2022 and 2023 that investigated how detection of European green crab eDNA is affected by sampling season, green crab density, and the time at which samples are collected across a tide cycle. The data include sample site locations and descriptive categories, volume of water (L) filtered for eDNA analysis for each sampling event...

In this study, we demonstrate that infectious hematopoietic necrosis virus (IHNV), which made a host jump from sockeye salmon (Oncorhynchus nerka) to rainbow trout (O. mykiss), has not conformed to classical pathogen evolution theory. We quantified virulence in the endemic and novel hosts using common garden in vivo experiments with 16 archival IHNV isolates collected from 1972-2017...

The content contains metadata from an eDNA survey that assessed the efficacy of an autonomous eDNA sampler for tracking Chinook, sockeye, and coho salmon migrating through the Lake Washington Ship Canal between June and September 2022.

Spawning distribution maps for Upper Willamette River (UWR) spring Chinook salmon were created for the historical period (approximately 1910-1940), and for the present-day period (2003-2023). These maps were created as a tool to visualize generalized, reach-scale patterns of spawning distribution before and after the construction of high-head dams and other large-scale anthropogenic...

We conducted a pilot study to evaluate the extent of cold water refuge use by juvenile outmigrating fall-run Chinook salmon (Oncorhynchus tshawytscha) in relation to managed water flows in the Klamath River. Juvenile fall-run Chinook salmon were captured and implanted with passive integrated transponder (PIT) tags and subsequently detected by submersible antennas that were strategically...

In the western United States, there has been a long history of planting fish into historically fishless mountain lakes for the purpose of recreational fishing. This practice can have detrimental effects to lake ecosystems, particularly amphibian populations. We compiled records of fish plantings into lakes on the Olympic Peninsula in western Washington State dating back to 1930. Our...
