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.

There's a new tool available to control the sea lamprey population in the Great Lakes.

For the first time, the U.S. Environmental Protection Agency has approved a synthetic mating lure to help trap sea lampreys before they spawn.

The mating pheromone is a scent released by male sea lampreys to lure females to nesting sites.
