Blood-sucking vampire fish… on this CurrentCast.

Sea lamprey, an invasive species in the Great Lakes, attach themselves to other fish and suck their blood and other body fluids.

Sea Lampreys

Discovered in the late 1800s, lamprey had invaded the entire Great Lakes system by the 1940s, devastating many once vibrant fisheries.

Ron Kinnunen of Michigan Sea Grant says the lamprey spend the early part of their life cycle in local rivers…

Kinnunen: “They’re only out in the lake for a short time –about twelve to eighteen months – where they mature into adults and during that time they can kill about forty pounds of fish.”

These plants grow into monocultures which threaten biodiversity and hurt wetland function. To find out more about invasive Phragmites and community Phragbusting, please read on.
