In recent years, The Great Lakes have been terrorized by a little, tiny foe called the Sea Lamprey. Usually found in the Atlantic, the parasite has been killing fish by the millions each year feeding on it’s blood and moving on to larger prey once it’s done. Scientists have been working to develop the most effective way to rid our waters of these tiny terrors. Michael Wagner, Fish ecologist and MSU professor, guides us through research on a plan to remove lampreys by smell.
