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 microg 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.
黑头软口鲦鱼（Pimephales promelas）幼体由暴露于铜（Cu）或未接触过铜的雌鱼产出，然后使用400和800微克/升的铜浓度进行96小时存活试验。进行了三次存活挑战：第一次存活试验以0日龄幼体为对象，而第二次和第三次分别以8日龄和15日龄幼体为对象。本研究结果表明，母体遗传的铜耐受性持续时间相对较短，因为其持续时间不到8天。
