Researchers develop tool to fight lamprey

A recently discovered chemical compound that makes it diffi cult for invasive sea lamprey to find their breeding grounds may be a new tool for controlling a parasite that threatens Great Lakes fish.

Anne Scott, an assistant professor of fisheries and wildlife at Michigan State University, and her research team are creating a new method of sea lamprey control using a newly discovered chemical compound, petromyzonol tetrasolfate — also known as 3sPZS.

It is similar to a pheromone that male sea lampreys release in rivers and streams before breeding.
