A renewed effort to fight invasive mussels in the Great Lakes is underway.
Invasive quagga and zebra mussels aren’t new to the Great Lakes. But according to some experts, they’re among the greatest threats to the ecosystem.
Dan Molloy is an expert in aquatic invasive species, especially the quagga mussel.
"Their populations can explode, they eat microscopic plants which are the foundation of the ecosystem, and they’re the only freshwater mussel or clam that can attach to thing."
