Brief description

Dreissena polymorpha (I1957) 0265 (39449820624)To date, D. polymorpha has been the most aggressive freshwater invader worldwide. Dreissenids are the only freshwater bivalves that attach to hard substrates in high densities and have a planktonic larval stage. This life history facilitates their abilities as invaders, and allows them to become enormously abundant when introduced into a new water body. Once introduced their populations can grow rapidly, and the total biomass of a population can exceed 10 times that of all other native benthic invertebrates. D. polymorpha is native to the drainage basins of the Black, Caspian and Aral Seas. During the nineteenth century its range has expanded westward to most of western Europe, the UK, and North America, where it is found in the Great Lakes and all major river drainages east of the Rocky Mountains and causes multiple economic impacts on fisheries, aquaculture, water attractions and aquatic transport (CABI 2019).

Status and distribution in Luxembourg

Records of Dreissena polymorpha (Pallas, 1771) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2021-05-17.

In Luxembourg, Dreissena polymorpha (Pallas, 1771) was first mentioned by Victor Ferrant in 1892 as occurring in the Moselle river (Ferrant 1892; Dhur & Massard 1995; MNHNL 2000-).

Currently, 18 records of the zebra mussel are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).
