Chinese Mitten Crab

Eriocheir sinensis H. Milne Edwards 1853

Alien species

The Chinese mitten crab already appears in Belgium from 1933. The crab originates from the Far East and was presumably brought to Europe as a larva in the ballast water of ships. From Germany, the species spread through Northern- and Western-Europe. The Chinese mitten crab Eriocheir sinensis predominantly lives in rivers, but migrates seaward in the late summer to breed in the brackish part of the estuaries. The egg-carrying females spend the winter at sea, and return to the brackish part of the estuary in spring to release the larvae in the water which then develop to juvenile crabs. These juveniles migrate back up the rivers, streams and canals to complete the life cycle.

Deze krab met wollige scharen komt reeds vanaf 1933 in België voor. Deze krab is oorspronkelijk afkomstig uit het Verre Oosten en werd vermoedelijk meegebracht naar Europa als larve in ballastwater van schepen. Vanuit Duitsland heeft de soort zich verspreid doorheen Noord- en West-Europa. De Chinese wolhandkrab leeft voornamelijk in rivieren, maar trekt in de late zomer zeewaarts om te broeden in het brakke deel van riviermondingen. De eierdragende wijfjes brengen de winter door in zee en komen in de lente terug naar het brakke deel van estuaria om er de larven in het water vrij te laten en verder te laten ontwikkelen tot juveniele krabbetjes. Later trekken deze dan weer geleidelijk de rivier, stromen en kanalen op, waar ze hun levenscyclus voltooien.
