在实验室测试中，来自一个无梭子鱼池塘的大约 20 000 只黑头鲦鱼自然种群中的个体在遇到梭子鱼气味时没有做出适当的反捕食行为反应。然而，在将 10 条梭子鱼放入池塘 14 天后，米诺鱼就开始识别梭子鱼的气味。实验室研究表明，黑头呆鱼获得捕食者识别的几种可能机制。这项研究表明，这些或类似的过程可以使野外捕食者识别发生重大变化。
Individuals from a natural population of approximately 20 000 fathead minnows from a pike-free pond did not respond with appropriate anti-predator behaviour upon encountering pike odour in laboratory tests. However, 14 days after 10 pike were stocked into the pond, minnows had acquired recognition of pike odour. Laboratory studies have indicated several possible mechanisms for acquiring predator recognition in fathead minnows. This study indicates that these, or similar processes, can produce major changes in predator recognition in the wild.
