Global Range: (20,000-200,000 square km (about 8000-80,000 square miles)) This species is native from Chesapeake Bay southward through the Gulf of Mexico but was introduced into the Hudson River, New York, as early as 1937 and later to the lower Charles River, Massachusetts, according to Rehder (1937), Jacobson (1953) and Carlton (1992). Benson et al. (2001) cite invasions in Alabama, Florida, Kentucky, and Tennessee.

Mytilopsis leucophaeata is a species of small bivalve mollusc in the false mussel family, Dreissenidae. It is commonly known as Conrad's false mussel or the Dark false mussel.
Identification[edit]
It can look very similar to the zebra mussel, with similar stripes, but it can be distinguished from it by an apophysis or projection on the inside of the shell near the umbo.[1] Shell length ranges between <1 and 2 cm, with an average length of 1 cm.[2]
Distribution[edit]
This species is native in the Gulf of Mexico,[3] and spread from there via ballast water, or attached to oysters that were moved, to the Hudson River in the 1930s,[4][5] and from there to other estuaries in the eastern US including Chesapeake Bay [6] as well as to the Pernambuco coast in northeastern Brazil.[7] This species also spread via ballast water to brackish waters in Europe, including the Baltic Sea, the North Sea, the Atlantic Ocean and the Mediterranean Sea as well as the Black Sea [5][8] and the Caspian Sea.[8]
Like the zebra mussel, this species is a significant biofouling pest in many countries, especially where it has been introduced in Europe.
Habitat[edit]
Mytilopsis leucophaeata is found in brackish water, at salinities ranging from 0.5 psu to about 12 psu, although its upper salinity limit is usually about 5–6 psu. It attaches to hard substrates, including oyster and true mussel shells and cages for them, rocks, boats, and pilings, and also to ropes.[9]

De brakwatermossel Mytilopsis leucophaeata is een Amerikaanse soort die bij ons terecht kwam via scheepvaart. De soort is typisch voor rivier-mondingen en komt in België voor in de Schelde. De brakwatermossel veroorzaakt aangroei- of ‘biofouling’ problemen in veel industriële sites in Europa, doordat de mossels zich gaan vestigen in koelwatersystemen. Het feit dat deze soort goed bestand is tegen schommelingen in temperatuur en zoutgehalte maakt het extra moeilijk om efficiënte tegenmaatregelen te nemen.
