Michigan State researchers target sea lamprey’s ‘signals’ to protect fisheries

Research into sea lamprey chemical communication could add a powerful new tool to the fight against one of the Great Lakes’ most destructive invasive species.
Scientists at Michigan State University and their collaborators are studying ways to disrupt the pheromones that sea lampreys use to find mates, potentially reducing reproduction without harming other fish. Their latest findings, published in the Journal of Chromatography B, highlight how understanding the parasite’s unique biology could complement the control methods that have protected Great Lakes fisheries for decades.
