Eriocheir sinensis H. Milne-Edwards, 1853 is a migrating crab which has invaded Europe and North America from its native region of Asia. During its mass migrations it contributes to the temporary local extinction of native invertebrates. It modifies habitats by causing erosion due to its intensive burrowing activity and costs fisheries and aquaculture several hundreds of thousands of dollars per year by consuming bait and trapped fish, as well as by damaging gear (GISD 2019).

Status and distribution in Luxembourg

Eriocheir sinensis H. Milne-Edwards, 1853 was first documented in Luxembourg in 1978 by Claude Meisch who found one individual in a pond of the Haff Réimech nature conservation reserve, municipality of Schengen (Meisch 1978 cit. in Dhur & Massard 1995).

Field research by Dhur and Massard in the years 1992-1993 did not find Eriocheir sinensis in the ecosystem of the border Moselle (Dhur & Massard 1995): “It seems likely that currently the species, even if its presence seems confirmed for the period before 1960, no longer populates the waters of the Luxembourg Moselle. A call to fishermen in 1994 (Massard 1994) 1 for them to report a possible presence of Eriocheir did not produce any results. In fact, after its expansion phase, Eriocheir has become considerably scarcer over the past forty years in most of the colonised areas of northern France and the Benelux (Vigneux et al. 1993). No E. sinensis stations are indicated in Lorraine by Vigneux et al. (1993), neither for the period before 1960 nor for the one after.”

There is no distribution map available because no data has been entered into the Recorder-Lux database so far (MNHNL, iNaturalist & GBIF 2019).

Risk assessment
