Reproducing Grass Carp populations are not desired in many natural environments in the United States. Determining if reproduction is occurring, and linking reproduction to adult fish, requires capturing larval Grass Carp. A 4x4 Latin-square design was used to assess efficacy of four different light colors at capturing larval Grass Carp in quatrefoil light traps. The experiments were...

This data release contains mark-recapture and associated environmental data for blue sucker (Cycleptus elongatus) collected in the lower Colorado River, Texas, from 2016 through 2026. The release includes capture records from 16 field events, combined into 13 primary sampling occasions for analysis, across up to 40 electrofishing sites, with information on sampling dates, site...

Embryonic zebrafish (Danio rerio) were exposed to 0, 1.93, or 15.46 micrograms per liter of total polycyclic aromatic hydrocarbons (tPAHs) present from a low energy water accommodated fraction (LEWAF) of crude oil from the Brazilian oil spill in 2019. Embryos were exposed from 4 hours post fertilization (hpf) through hatching and sampled at 24, 48, 72,96, 120, 144, or 168 hpf. Zebrafish...

PFAS measurements were made in environmental media from the Great Lakes region, including surface microlayer, water column, suspended sediment, bed sediment, and porewater. Environmental media were collected from various tributaries in the Root River (Wisconsin), Oak Creek (Wisconsin), and Howe Drain (Michigan) watersheds in the Great Lakes region. Field samples were collected within...

Data describe designed environmental DNA (eDNA) laboratory experiments for the estimation of eDNA shedding and degradation rates for adult Mucket (Ortmanniana ligamentina) at different biomass densities in a closed system. Parameters described include descriptions of laboratory collected water samples that were tested to estimate concentration of Mucket DNA, qPCR results and associated...

This project contains design parameters and an overview of the hydraulic characterization of the U.S. Geological Survey (USGS), Columbia Environmental Research Center (CERC) eco-flume. The eco-flume was designed in collaboration with the St. Anthony Falls Laboratory at the University of Minnesota to explore complex ecological phenomena that occur in natural rivers. The overall design was...

This data describes the relative luminescence units (RLUs) and relative fluorescence units (RFUs) of lysates of estrogen responsive chemically-activated luciferase expression human breast carcinoma VM7LucERbeta9 cells which were exposed for 24 h to 17beta-estradiol dilutions, or dilutions of sediment extracts collected from various locations within the Conasauga River Basin in the...

This data release supports a pilot laboratory study evaluating the bioaccumulation and reproductive effects of dietary selenium on the endangered Topeka shiner (Notropis topeka). Adult fish were exposed under controlled flow-through conditions to three diets containing graded concentrations of seleno-L-methionine (control, 5.50, and 14.0 micrograms Se/g dry weight) to simulate...

Accurate age data is essential for modeling fish population dynamics and informing management decisions. Estimating age in cyprinid fishes like the invasive silver carp is challenging. During this study we evaluated precision and bias in age estimates of silver carp collected from the Illinois River, Illinois using seven structures: the first and second section of the ossified pectoral...

These datasets document locations of and water temperature recorded by Hobo Water Temp Pro series loggers (Onset Computer Corp., Bourne, MA) deployed by the USGS Comprehensive Sturgeon Research Project at up to 31 locations in the Lower Missouri River (from the Gavins Point Dam near Yankton, South Dakota to its confluence with the Mississippi River near St. Louis, Missouri) and 7...

These datasets document locations of and water temperature recorded by Hobo Water Temp Pro series loggers (Onset Computer Corp., Bourne, MA) deployed by the USGS Comprehensive Sturgeon Research Project at up to 29 locations in the Lower Missouri River (from the Gavins Point Dam near Yankton, South Dakota to its confluence with the Mississippi River near St. Louis, Missouri) and 7...

The Powder River from Broadus, Montana to Terry, Montana was surveyed from June 13-19, 2025 to map the range of habitats, including spawning habitats available to be used by the endangered pallid sturgeon (Scaphirhynchus albus). Pallid sturgeon typically occupy the Powder River in the spring to early summer in years when flows are high. We surveyed potential spawning habitats and...
