Vestigt de blauwe zwemkrab, Callinectes sapidus zich blijvend in de Zuidelijke Noordzee?

In 1984 Callinectes sapidus was observed in northern France, the Netherlands (North Sea, Waddensea) and very probably in Belgium. After a series of observations in the river Scheldt (e.g. an egg-bearing female) and a record in the Humber estuary, it seems possible that the Blue Crab is settling or has settled in the southern North Sea.
