  • The sea lamprey is an ancient, parasitic fish that invaded the Great Lakes a century ago, where it triggered the collapse of many fisheries1. Like many fishes, this species relies on chemical cues to mediate key aspects of its life, including migration and reproduction2,3. Here we report the discovery of a multicomponent steroidal pheromone that is released by stream-dwelling larval lamprey and guides adults to spawning streams. We isolated three compounds with pheromonal activity (in… CONTINUE READING
