Those Nasty Old Zebra Mussels

From U.S. Fish and Wildlife Service: Fisheries

Brought here from Europe in ships’ ballast water; zebra mussels were first discovered in the Great Lakes region in 1988. Zebra mussels have inflicted tremendous damage to native ecosystems and to facilities using water. And, as zebra mussel populations in an area increase, native mussels decrease; a strong indication that zebra mussels are the cause. #NISAW
