No influence after various exposure times on the biotransformation rate constants of benzo(a)anthracene in fathead minnow (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).
Effects of waterborne exposure of 17 beta -estradiol on secondary sex characteristics and gonads of fathead minnows (Pimephales promelas)

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

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...
Survival endpoints for juvenile rainbow trout (Oncorhynchus mykiss) and fathead minnows (Pimephales promelas) in response to exposure to wildland firefighting chemicals. Exposures were either attenuated or pulsed. For attenuated exposures, chemical treatment was applied at the beginning of the exposure and control water was added for the duration of the assay so chemical concentration gradually decreased over time. In pulsed exposures, organisms were exposed to chemical treatments for a set period of time and then moved to chambers without chemical applied. This data set includes data from seven assays and include treatments under various exposure conditions such as different background water hardness, chemical...
