Predator avoidance performance of larval fathead minnows (Pimephales promelas) following short-term exposure to estrogen mixtures.

Aquatic organisms exposed to endocrine disrupting compounds (EDCs) at early life-stages may have reduced reproductive fitness via disruption of reproductive and non-reproductive behavioral and physiological pathways. Survival to reproductive age relies upon optimal non-reproductive trait expression, such as adequate predator avoidance responses, which may be impacted through EDC exposure. During a predator-prey confrontation, larval fish use an innate C-start escape behavior to rapidly move away from an approaching threat.
