Planning a boating outing this holiday weekend? State officials are asking that you don't move a mussel.
Boaters are asked to clean, drain and dry their boats before heading to waterways and lakes over Labor Day weekend in an attempt to prevent the spread of harmful Quagga and Zebra mussels.
State border inspectors also will be checking for the invasive mussels on watercraft entering the state, according to the California Farm Bureau Federation.
Quagga mussels were first found in the Colorado River system in January 2007 and later were found in San Diego and Riverside counties. Zebra mussels were found in a San Benito County reservoir in January 2008, states a Department of Fish and Game news release.
The destructive mussels can attach to and damage boat trailers, cooling systems, boat hulls and steering equipment and can be transported and spread to other bodies of water. Water in boat engines and other parts of the craft also can carry mussel larvae - called veligers - which can spread into waterways and lakes, the release states.
State law makes it illegal to possess or transport either of the mollusks and gives Fish and Game, state Department of Food and Agriculture and state parks officials authority to search and quarantine boats with suspected or confirmed mussel contamination.
The mussels can severely damage boats by ruining engines, increasing drag, jamming steering equipment and damaging hulls.
Boaters are asked to inspect all exposed boat surfaces, wash boat hulls thoroughly, remove plants from boat and trailer, drain all water, dry livewells and bait buckets and throw bait fish in the trash. All watercraft should be dried for at least five days between launches in different fresh bodies of water, the release states.
State officials also suggest that boaters plan for possible launch restrictions and inspections and should contact officials at their waterway or lake destination before leaving home.
Potentially contaminated watercraft could be turned away, the release states.
Quagga mussels arrived in the U.S. from Ukraine in 1989. The mussel, typically the size of a fingernail but able to grow to about two inches long, can colonize on hard and soft surfaces in freshwater from the surface to depths of more than 400 feet, according to Department of Fish and Game statistics.
Zebra mussels arrived in the U.S. from Europe one year earlier. The mussels are the same size as Quagga mussels and have the same growth potential, but can inhabit fresh water at depths from four to 180 feet and prefer hard surfaces.
Boaters or other people involved in lake or water activity who want more information about the invasive mussels may call (866) 440-9530.
