They are damaging the natural eco-system by eating the food native fish and mussels would eat, hence crowding out native populations. Recreational and commercial boating is affected as the mussels damage boats, fishing populations, and infrastructure. This includes the boat, propeller, trailer, and equipment. Flush the engine cooling system, live wells, and bilge with hot water. Rinse any other areas that get wet.
Air dry the boat and other equipment for five days before using in waters that are unaffected.
Examine the boat exterior for mussels if it has been docked in infested waters. If the exterior of the boat has algae on it or feels gritty, your boat could be infested with mussels or their young. Clean with hot water, and dry for at least five days before putting the boat back in the water. Do not reuse bait if exposed to infested waters. Contact the New York Sea Grant for more information about zebra mussels.
