Brief description

Corbicula flumineaCorbicula fluminea (O.F. Müller, 1774) is an inland water, filter-feeding bivalve native to southeast Asia but causing numerous problems in its new range of distribution in the Americas, Europe and Australia. C. fluminea spreads when it is attached to boats or carried in ballast water, used as bait, sold through the aquarium trade and carried with water currents. Its reproductive success and ability to spread rapidly has resulted in this species having one of the most rapid expansions of any non-native species in North America. Before the invasion of the zebra mussel Dreissena polymorpha, in North America, C. fluminea was described by McMahon (1983) as ‘one of the most important molluscan pest species ever introduced into the United States’. Aldridge and Muller (2001) review the potential impacts that the spread of C. fluminea may have on British industry and aquatic systems. In the DAISIE project, C. fluminea is listed on the 100 worst invasive species (CABI 2019).

Status and distribution in Luxembourg

In Luxembourg, Corbicula fluminea (O.F. Müller, 1774) was first documented by Klaus Groh on 17 June 1996 in the Moselle river in the municipality of Remich (MNHNL 2000-). It was expected by 1995 that the species would soon appear in the Moselle (Dhur & Massard 1995: 150).

An identification sheet of the species has been published by the MECDD in French and German.
