The problemAquatic invaders like zebra mussels, Eurasian watermilfoil, and the fish disease viral hemorrhagic septicemia (VHS) are non-native species that cause damage to watercraft and equipment, and can interfere with our enjoyment of water recreation. These organisms also harm native plants and animals, reduce habitat for wildlife, change natural ecosystems, create health risks for humans, and result in negative economic impacts.
Easily overlooked, the main way that these aquatic invaders spread is by hitching rides on boats, trailers, and gear used by anglers, boaters, and other recreationists. If you leave a water access site without taking precautions, you may be transporting these harmful organisms from one body of water to another. |
