What You Can Do to Help:
Help Stop the Spread:
Zebra and quagga mussels cause devastating impacts on municipal water systems, water recreation opportunities and businesses, and fisheries. Currently, they are widespread in eastern and midwestern states, and are rapidly spreading in Southern California. Zebra mussels have been found as far north as San Benito County. We need your help to stop these mussels from spreading to uninfested lakes, rivers and streams in California.
Zebra and quagga mussels are transported from one waterbody to another in vessels. Microscopic larval mussels can “hitchhike” in water remaining in livewells, bilge tanks, engine cooling systems, and bait buckets. Juvenile and adult mussels can hitchhike attached to boat hulls, engine drive units, and boat trailers. Adult zebra and quagga mussels can survive for several days out of the water if in a moist, shaded area, and for over a week in wet areas such as bilges and livewells.
