Sea lampreys have devastated Michigan waters for decades. But now, scientists hope that sterilizing some males will help control the population.
Marc Gaden is with the Great Lakes Fishery Commission.
"The goal is to overwhelm the lampreys, to have the sterilized males out-compete the fertile males, and reduce spawning in that system to the bare minimum," Gaden said.
According to scientists, the invasive species has the ability to wipe out native life.
