This invasive species originally from the
Black and
Caspian Sea was introduced into US waters in the ballast of commercial shipping and has spread across the country attached to boats. At least five days out of the water is required to kill this pest. A thorough cleaning of your boat when leaving a body of water contaminated with mussels is the best defense.
In the Great Lakes, the sport fishing industry is being effected for some species of fish because the mussels compete for the plankton that are at the bottom of the food web.
Eventually, every inland lake and coastal water will have much clearer water clogged engines and water intakes thanks to this pest. Last summer on a trip to Sedona I was surprised to learn that Zebra and Quagga mussels have become a serious problem in ARIZONIA
From the Arizonia Fish and Game Department website at:

“Prolific quagga mussels have invaded lakes Pleasant, Havasu, Mead and Mohave. These tiny invaders can easily hitchhike on your boat – 10,000 or more microscopic larvae to fit into a teaspoon of water. So please DON’T Move A Mussel,” said Tom McMahon, invasive species coordinator for the Game and Fish Department.
In fact, these tiny invaders are so prolific that a single adult quagga mussel can produce up to a half-million microscopic larvae in a single year and can eventually carpet vast areas of a lake. So please Drain, Clean and Dry your boat each and every time you visit a lake – any lake.
1. Drain the water from the boat, livewell and the lower unit
2. Clean the hull and remove all plant and animal material
3. Dry the boat and inspect all exposed surfaces ?
