For more than a century, an invasive species has been literally sucking the life out of the Great Lakes. They’re known as sea lampreys. After nearly decimating commercial fishing operations in the early 20th Century, a management program was created to keep the lampreys at bay.  It’s been successful: the number of sea lampreys has been reduced by 90% since the program first began. But the work has been on-going and now cuts to the federal program are threatening that progress.

She joins Lake Effect’s Joy Powers, along with Mark Gaden, the executive secretary of the Great Lakes Fishery Commission, whose work was featured in the piece.
