COMMON NAME:Quagga mussel
SCIENTIFIC NAME:Dreissena bugensis
DESCRIPTION:The quagga mussel is a filter-feeding, freshwater, bivalve mollusk. It is pale toward the end of its hinge and about 3/4" wide.
HABITAT:Quagga mussels inhabit freshwater habitats up to depths of 90 ft., attaching to most surfaces including sand, silt and hard substrates.
THREAT:Invasive mussels displace native species, attach to and cover many surfaces, have sharp shells and are a nuisance to humans. Although they have some predators, they breed faster than they can be consumed. As filter-feeders, they remove particles from the water, affect the clarity, content and ultimately the food chain of aquatic ecosystems.
Once established, very little can be done apart from manual removal. In closed human systems such as water treatment plants, chemical, thermal, electrical and biological controls can be used. The best method is prevention through cleaning boats, bait buckets, and gear.
