Researchers from Michigan State University, the University of Minnesota and Western Michigan University have homed in on a fatty molecule that directs the destructive eels’ migration. The results, published in the current issue of PNAS, could lead to better ways to control sea lampreys.
“We’ve found a pheromone, a fatty acid derivative, that’s released by larval sea lamprey and guides migratory adults to spawning grounds,” said Weiming Li, MSU professor of fisheries and wildlife and co-lead author of the study. “Because the pheromone bridges two distinct life stages and transmits through two different habitats, it holds a potential to disrupt adult sea lamprey as they try to reproduce.”
Scientists have suspected that such an odorant existed for decades, but the identity of such odorants have remained elusive.
