Fathead minnow Pimephales promelas larvae were produced by either copper (Cu)‐exposed or naïve females and then subjected to a 96 h survival test using Cu concentrations of 400 and 800 μg l −1 . Three survival challenges were conducted: the first survival test featured 0 day‐old larvae while the second and third featured 8 and 15 day‐old larvae, respectively. The results of this study show that maternally derived Cu tolerance was relatively short‐lived as it persisted for <8 days.
