Keep the zebra mussel out of the cove!
In recent years, a fingernail-sized, striped mussel called the zebra mussel has been introduced to the waters of North America from the Caspian Sea region of eastern Europe. This exotic pest has no natural predators on this continent to keep its population in check and has caused serious problems in North American waters. The zebra mussel has the potential to clog water-intake systems, degrade aquatic environments, harm fish and native mussel populations and contribute to taste and odor problems in the production of drinking water.
The introduction of the zebra mussel in Carvins Cove would be bad news, since a reproducing population of the mussel can spread rapidly through the water supply.
The zebra mussel page on the Virginia Cooperative Extension website provides more information about this exotic pest.
