This data set summarizes electrofishing effort, observations, and tissue sampling of aquatic vertebrates near Yellow Pine, Idaho. Sampling was conducted using a backpack electrofishing unit at two reference sites including Cane Creek and Sugar Creek, and at three mine impact sites including Sugar Creek and Cinnabar Creek. Juvenile Bull Trout (Salvelinus confluentus) were present at all five sites and were the primary species targeted during our sampling effort. Additional tissue samples of Sculpin, and amphibians were taken when available. Where possible, a two pass (quantitative depletion) electrofishing survey was conducted at each site for non-USGS stakeholders (Nez Perce Tribe and Idaho Department of Fish and Game) to estimate population density if necessary to fit project needs. Electrofishing efforts were immediately halted when adult spawning Bull Trout were encountered so as to minimize harm to that species and in those cases a two pass quantitative depletion survey was not completed. Both summarized and site specific data included are in tabular form. Data is presented in both .csv and .xlsx format, the content within the Excel workbook is the same content within each individual .csv and .jpeg.

PURPOSE: To monitor juvenile Atlantic salmon densities over time. DESCRIPTION: Indices of freshwater production are derived annually from electrofishing surveys in Southeast New Brunswick. Juvenile Atlantic salmon abundances at sites, divided by age or size group and reported in terms of number of fish per habitat area sampled (density), are obtained using successive removal sampling or catch per unit effort sampling (which is calibrated using successive removal sampling data). Sampling intensities vary among years and among rivers. This dataset comprises raw data on all fish captured and effort invested in the course of monitoring juvenile Atlantic salmon in Southeast, New Brunswick, from 1974 to 2024. Sampling was focused on habitat suitable for Atlantic salmon, and capture of any other species was incidental. PARAMETERS COLLECTED: Distribution (ecological); species counts (ecological); fish lengths (biological); fish weights (biological); point (spatial). USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

Data tables represents a telemetry study assessing the efficacy of sound and electricity used to herd Silver Carp (Hypophthalmichthys molitrix). The study occurred in Jonathan Creek Embayment of Kentucky Lake, Kentucky using 10 telemetered Silver Carp and 46 passive acoustic receivers. Two herding boats traveled at 2.22 meters per second along bank-to-bank transects through the study area (longitudinal progression rate = 0.37 meters per second) emitting sound and electricity (“stimulus”) or no added stimuli (“control”). Fish movement responses included fish presence in the refuge-zones located at either end of the embayment, fish presence fore of herding boats, and fish presence within 100 meters, 200 meters, 400 meters, and 800 meters of the herding boats, and fish velocity.

The dataset is composed of six tables containing environmental DNA (eDNA) and electrofishing data from American eel (Anguilla rostrata) surveys conducted on parts of the Mohawk River watershed and tributaries to the Hudson River in New York. The dataset includes (a) eDNA data from 36 sites in the Mohawk River watershed and adjacent areas including parts of the Eastern Erie Canal, Mohawk River, and tributaries that were sampled in spring 2021 and again in summer 2021,(b) paired eDNA/electrofishing data from 15 sites on tributaries to the Hudson River that were sampled between 2020 and 2021, and (c) model output of predicted American eel density from all sites in the Mohawk River watershed and adjacent areas where eDNA was detected. The table "MohawkHudsonEel_MohawkScreening_eDNAData" contains eDNA data from the 36 sites in the Mohawk River watershed, the table "MohawkHudsonEel_MohawkScreening_SiteData" contains supporting information on the 36 sites in the Mohawk River watershed, the table "MohawkHudsonEel_HudsonTribCalibration_LWData" contains the length and weight for all American eel captured during electrofishing surveys from the 15 sites on tributaries to the Hudson River, the table "MohawkHudsonEel_HudsonTribCalibration_eDNAData" contains eDNA data from the 15 sites on tributaries to the Hudson River, the table "MohawkHudsonEel_HudsonTribCalibration_SiteData" contains supporting information on the 15 sites on tributaries to the Hudson River including the dimensions of the reaches where electrofishing was conducted, and the table "MohawkHudsonEel_MohawkScreening_DensityEstimate" contains predicted density of American eel estimated from eDNA concentration using linear regression from all sites in the Mohawk River watershed and adjacent areas where eDNA was detected.

PURPOSE: To track juvenile Atlantic salmon densities. DESCRIPTION: Indices of freshwater production are derived annually from electrofishing surveys in the rivers of Nova Scotia flowing into the Gulf of St. Lawrence. Fixed site sampling for juvenile salmon has been conducted most consistently since the mid-1980s for these rivers. Juvenile salmon abundances at sites, in terms of number of fish per habitat area sampled by age or size group (densities), are obtained using successive removal sampling or catch per unit effort sampling calibrated to densities. Sampling intensities vary among years and among rivers. PARAMETERS COLLECTED: Distribution (ecological); species counts (ecological); point (spatial). USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

We collected electrofishing, environmental DNA (eDNA), and habitat data from 2022 to 2024 in the Oregon portion of the Goose Lake Basin. Data were collected by the U.S. Geological Survey (USGS) and Oregon State University (OSU) to monitor native and non-native fish distributions in the Basin, and to relate observed abundances to specific habitat features. Sampling was conducted in collaboration with Oregon Department of Fish and Wildlife (ODFW) based on previous survey efforts, using a stratified random subset of sites surveyed by ODFW in 2007 and following the same protocols. We added eDNA to evaluate its efficacy as an alternative to traditional fish sampling methods, and all sample processing was carried out by the Levi Lab at OSU. During fish sampling efforts, we collected habitat data including channel width, depth, temperature, dissolved oxygen, conductivity, and substrate. These data are part of a broader, comprehensive monitoring effort in the Basin.

The table provides all fish collected using two different electrofishing methods at Illinois River sites in 2012 and 2013. Length and weights were taken on most species and gender was taken from Silver Carp. Fishes were categorized whether they were netters (caught by nets) or jumpers (jumped in the boat while sampling) and only netters were used in analyses. Large numbers of shad were collected in 2013 and an additional spreadsheet includes abundance data in an aggregated form for those sites. The data is not sensitive/classified and there are no legal restrictions on who may obtain or use the data.

This database contains data on e-fishing results for monitoring conducted in various streams (primarily Antelope, Mill and Deer Creeks) by Red Bluff CDFW staff to investigate juvenile salmonid and other encountered species.
