Data were collected in association with the application of two physical barrier treatments, bentonite clay (a sealing agent) and expanding foam (an insulation sealant), in natural pond-burrows to suppress or kill the invasive red swamp crayfish (Procambarus clarkii). Data include burrow diameter and depth, crayfish sex and size, and determination of the treatment reaching the burrow chamber.
Using juvenile individuals of 3 species of carp (Family: Cyprinidae), we tested the potential for six amino acids to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid were tested on Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmichthys nobilis), and Silver Carp (H. molitrix) to provide a comparison among amino acids both within and among species. Each row in the data set represents exposure to a single amino acid. Each individual fish was exposed to up to four amino acids sequentially in a random order, representing a trial; each individual was...
We investigated whether the length of time fire chemical weathers on a terrestrial substrate before mixing into aquatic environments alters the chemical’s toxicity when encountered by juvenile rainbow trout. We also looked at whether the type of substrate where the chemical is applied affects its toxicity to juvenile rainbow trout after mixing into water. Two fire chemicals (Phos Chek LC95A-R and Phos Chek MVP-Fx) were applied to four substrate media (low organic content soil, high organic content soil, duff, and gravel) and allowed to age on the substrate for 7, 14, 28 or 56 days. At the end of the assigned weathering period, 96-hour assays were conducted by adding water to the dosed substrate and stocking each...

Alternative complement pathway assay data observed in adult largemouth bass plasma in response to an EE2 (17alpha-ethinylestradiol) or mixture of estrone and atrazine exposure under laboratory pond conditions, with associated fish identification information.
Data describe designed environmental DNA (eDNA) experiments for the estimation of eDNA shedding rates for the spectaclecase (Cumberlandia monodonta), mucket (Actinonaias ligamentina), and fatmucket (Lampsilis siliquoidea) from water samples collected in the laboratory under differing laboratory conditions. Shedding rates were tested under variable mussel biomass, diet, and temperature. Parameters described include descriptions of laboratory collected water samples that were tested to estimate concentration of spectaclecase, mucket or fatmucket DNA qPCR results, and associated quality assurance measurements.

Dataset consists of water and freshwater mussel concentrations of two pharmaceuticals, sertraline and acetaminophen, collected from a 14-day accumulation and 7-day elimination study. Samples (4 replicates) were collected at 0, 4, 12, 48, 96, 168, and 336 hours during the uptake phase of the exposure. Samples (4 replicates) were collected at time point 348, 360, 408, and 504 hours during the elimination phase of the exposure. Note the time points are sequential with the uptake portion of the study followed by the elimination portion of the study.
The data consists of survival, length and weight of grass carp and black carp gavaged with an oral dose of antimycin A in two carriers, corn oil and ethanol.
Physiological and molecular endpoints observed in juvenile largemouth bass in response to an estrogen (17α-ethinylestradiol) and subsequently a bacterial challenge (Edwardsiella piscicida) exposure under laboratory conditions. Also included are water quality and chemical concentration data.
Data describe designed environmental DNA (eDNA) experiments for the estimation of eDNA shedding rates for mucket (Actinonaias ligamentina) and fatmucket (Lampsilis siliquoidea) from water samples collected in the laboratory under differing food avilability scenarios. Parameters described include descriptions of laboratory collected water samples that were tested to estimate concentration of spectaclecase, mucket or fatmucket DNA qPCR results, and associated quality assurance measurements.

A piscicide delivery method was designed to selectively target black carp Mylopharyngodon piceus, an invasive species in North America which possesses specially adapted pharyngeal teeth for crushing mollusk prey. Bait was prepared by attaching a glass vial containing toxicant (antimycin A) to the exterior of Corbicula fluminea clam valve. The vial was designed to break by the force exerted from the fish’s (550 millimeter total length) pharyngeal teeth when the fish attempted to crush and consume the clam. Suitable vial size was tested for encapsulating piscicide and two attachment materials, aquarium epoxy and ultraviolet light (UV) cured attachment material. Toxic baits consisting of antimycin A piscicide were...

We determined acute and chronic toxicity of sodium chloride (NaCl) and sodium sulfate (Na2SO4) to up to 7 freshwater species of different taxa in a hardness water of 40 mg/L as CaCO3 and evaluated the effect of 4 hardness waters (15, 30, 60, and 120 mg/L as CaCO3) on acute toxicity of NaCl and Na2SO4 to 3 sensitive species tested in the acute exposures. This data release reports results from acute and chronic exposures with Ceriodaphnia dubia (cerios), Chironomus dilutus (midge), Hyalella azteca (amphipod), Hyla versicolor (gray treefrog), Lampsilis abrupta (pink mucket), Lampsilis siliquoidea (fatmucket), and Pimephales promelas (fathead minnow. Date include survival, size, and other endpoints and associated water...

Data describe designed environmental DNA (eDNA) experiments for the estimation of eDNA shedding rates for the spectaclecase (Cumberlandia monodonta), mucket (Actinonaias ligamentina), and fatmucket (Lampsilis siliquoidea) from water samples collected in the laboratory under differing laboratory conditions. Shedding rates were tested under variable mussel biomass, diet, and temperature.

We measured Survival endpoints for juvenile rainbow trout (Oncorhynchus mykiss) in response to exposure to wildland fire retardants. Exposures were <24 hours. We documented time to mortality hourly through 12 hours of exposure and again at 24 hours. This data set includes data for three current use fire retardants from the US Forest Service Qualified Products List (Phos-Chek 259-Fx, Phos-Chek MVP-Fx, and Phos-Chek LC-95A-R). Also included are water quality data measured in each treatment at the beginning of each assay and quality assurance/ quality control data which validates the accuracy of those water quality measurements.

This data set describes developmental and physiological effects observed in fathead minnow embryos that were exposed to sodium nitrate or conductivity-matched controls. Exposures were conducted in the laboratory from fertilization through 21 days post-fertilization (dpf). Nitrate doses were 0, 2, 5, 10, 25, or 100 milligrams per liter nitrate-nitrogen; conductivity controls were matched to the 10 and 100 milligrams per liter nitrate-nitrogen treatments. During the experiment, we assessed heart rate and percent arrhythmic heart beats at 3 dpf, timing of hatch and inflation of the posterior and anterior swim bladders, presence of pericardial edema or scoliosis, fish metrics at 21 dpf (fish length and weight; swim...
Data consists of dose, dose method, solvent, weight, length and survival of test species from bioassays following an Up-and-Down method conducted with Ziram.
We conducted multiple toxicity tests to (1) evaluate the survival and growth of juvenile mussels (Fatmucket, Lampsilis siliquoidea) in a standard 4-week and a longer-term 12-week exposures following a method refined from the standard method using two common reference toxicants (potassium chloride [KCl] and nickel [Ni]); (2) evaluate reproductive endpoints from reproductive KCl and Ni toxicity tests. Reproductive toxicity tests started with Fatmucket brooding mature glochidia to five concentrations of K and Ni for 6 weeks. Subsamples of glochidia were then removed from the adults to determine (1) the viability of brooded glochidia; (2) the viability of free glochidia in a 24-h additional exposure; and (3) success...
