A newly discovered chemical compound that makes it difficult for invasive sea lamprey to find their breeding grounds may be a new tool in the toolbox for controlling a parasite that threatens Great Lakes fish.
Anne Scott, an assistant professor at Michigan State University, and her team of researchers are creating a new method of sea lamprey control
TOBERMORY Over the past 20 years quadrillions of invasive mussels have been sucking the life out of the Great Lakes. They’re trapping nutrients, the basic building blocks of life, on the lake bottom. Without nutrients, organisms of all kinds - from the tiniest plankton to the largest fish - are vanishing. In Lakes Huron, Michigan, and Ontario, vast offshore areas have become “biological deserts,” heralding one of the biggest changes to the Earth’s freshwaters in 10,000 years.
TRAVERSE CITY — Contractors and the U.S. Army Corps of Engineers are still figuring out how much it’ll cost to build a new bidirectional fish passageway in Traverse City.
Nicknamed the vampire eel, parasitic lampreys have a round, tooth-filled mouth instead of true jaws like eels that rasp holes through the skin or scales of other fish to “drink” their bodily fluids.
