Waterborne 17α-Ethynylestradiol Affects Aggressive Behaviour of Male Fathead Minnows (Pimephales promelas) under Artificial Spawning Conditions
Among fishes, courtship behaviour and nesting defense are strong predictors of reproductive success. We conducted three experiments to assess the impacts of exposure to 17α-ethynylestradiol (EE2) on the ability of male fathead minnows (Pimephales promelas) to establish and defend a spawning territory. Fish were exposed to EE2 (2 or 8 ng L-1) for 27 days, while spawning conditions were gradually...
متن کاملBehavioral avoidance of fluoranthene by fathead minnows (Pimephales promelas).
A monitoring system was used to examine the behavioral response of fathead minnows (Pimephales promelas) to plumes of the polycyclic aromatic hydrocarbon fluoranthene. Previously unexposed fish and fish surviving acute exposure to fluoranthene were presented with three different concentrations of fluoranthene. Both groups of fish avoided fluoranthene. Pre-exposure did not enhance or diminish av...
متن کاملPathology of fathead minnows (Pimephales promelas) exposed to chlorine dioxide and chlorite.
Fathead minnows (Pimephales promelas) were exposed to the biocide chlorine dioxide (0.13 and 0.19 mg l-1) for up to 12 h and to its primary decomposition product, chlorite (177 and 304 mg l-1), for up to 96 h followed by recovery periods of up to 14 days. Chlorine dioxide exposure produced dose-dependent gill pathology including epithelial lifting, hypertrophy, hyperplasia, lamellar fusion, and...
متن کاملDetermination of vitellogenin kinetics in male fathead minnows (Pimephales promelas).
A lack of knowledge persists concerning the combination of kinetics on protein and mRNA levels of the most commonly used biomarker for estrogenic influences-vitellogenin (VTG). Consequently, male fathead minnows were exposed to 17alpha-ethinylestradiol (EE(2)) for 35 days, followed by an equally long depuration period in a flow-through system. VTG mRNA levels reached a plateau after 3 days of e...
متن کاملGene expression of fathead minnows (Pimephales promelas) exposed to two types of treated municipal wastewater effluents.
Contaminants of emerging concern (CECs) in treated municipal effluents have the potential to adversely impact exposed organisms prompting elevated public concern. Using transcriptomic tools, we investigated changes in gene expression and cellular pathways in the liver of male fathead minnows (Pimephales promelas) exposed to 5% concentrations of full secondary-treated (HTP) or advanced primary-t...
