Smell of death repels sea lampreys

Posted by: Ethan Buchinger

The Sea Lamprey has caused many problems since they arrived in the Great Lakes.   The Great Lakes Fishery Commission has battled these strange fish and have reduced its population by 90% but needs to keep funding its programs to keep the lamprey at bay.   Researchers from Michigan State University have been working with pheromones to attract lamprey and control their behaviors but a new project of using something called necromone, which essentially is the smell of death. The lamprey are repulsed by the necromone   and this could be used to our advantage.   Chemists are trying to distinguish this chemical to be used to isolate lamprey into certain areas so they can be controlled.   This website has a pretty cool video of the reaction of lamprey when necromone is poured in to their tank.
