No influence after various exposure times on the biotransformation rate constants of benzo(a)anthracene in fathead minnow (Pimephales promelas)
Effects of waterborne exposure of 17 beta -estradiol on secondary sex characteristics and gonads of fathead minnows (Pimephales promelas)
Sediment-quality and water-toxicity data from 10 sites on the Westside Creeks and San Antonio River, San Antonio, Texas, 2014
Sediment samples and samples for water-toxicity testing were collected during 2014 from several streams in San Antonio, Texas known locally as the Westside creeks (Alazán, Apache, Martínez, and San Pedro Creeks) and from the San Antonio River. Samples were collected once during base-flow and again after periods of storm-water runoff (post-storm conditions) to determine baseline sediment- and water-quality conditions. Streambed-sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides, polychlorinated biphenyls (PCBs), brominated flame retardants, and polycyclic aromatic hydrocarbons (PAHs).

Chronic effects of the herbicide diuron on freshwater cladocerans, amphipods, midges, minnows, worms, and snails
Using probabilistic neural networks to model the toxicity of chemicals to the fathead minnow (Pimephales promelas): A study based on 865 compounds
Physical, Chemical, and Bioassay Data from the Study on Effects of Elevated Major Ions in Surface Water Contaminated by a Produced Water from Oil Production
This dataset characterizes sensitivity of fathead minnow and a unionid mussel to elevated major ions in produced water from oil and gas extraction process.
Impairment of the reproductive potential of male fathead minnows by environmentally relevant exposures to 4-nonylphenolf
The synthetic organic compound 4-nonylphenol (NP) has been detected in many human-impacted surface waters in North America. In this study, we examined the ability of NP to alter reproductive competence in male fathead minnows after a 28 day flow-through exposure in a range of environmentally relevant concentrations bracketing the U.S. Environmental Protection Agency toxicity-based NP chronic exposure criterion of 6.1 μg NP/L. Exposure to NP at and above the EPA chronic exposure criterion resulted in an induction of plasma vitellogenin (VTG) within 14 days. However, 7 days after the cessation of exposure, VTG concentrations had dropped more than 50% and few males expressed VTG above the detection threshold. All of...
Adverse reproductive effects in male fathead minnows (Pimephales promelas) exposed to environmentally relevant concentrations of the natural oestrogens, oestradiol and oestrone
Survey data was integrated within a GIS by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which allows for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by state boundaries. Addressing the management and conservation challenges for native fishes will require the ability to “data mine” the extensive existing information on distribution and abundance of species available from aquatic survey programs. Results from such syntheses can be used to assess the current conservation status of native fishes, quantify the extent of species invasions, and establish baseline distributions with which to evaluate...
