The Chinese mitten crab was introduced as an alien invader into western Europe, probably initially in ballast water, in about 1912. Since the early 1990s, mitten crab numbers in the Thames catchment have risen dramatically. The crabs are ravenous omnivores, feeding on the indigenous freshwater fauna and flora, and outcompeting native crayfish.
