|The European Green Crab has set|
its sights on the waters of
the West Coast of British Columbia
as a place to set up a new home
Arriving in packing material in California, it's estimated that the first sighting of the species in British Columbia was between 1998 and 1999.
The crab can be found on protected shores, cobble beaches, sandflats and tidal marshes on the B. C. coast, with isolated populations found on the Central Coast, next on the invasion list perhaps are the waters of the North Coast.
The concerns of DFO when it comes to the Crab are the threats they pose to the marine ecosystem of the West Coast, with the newish arrivals voracious predators that feed on a variety of intertidal animals, including oysters, mussels clams and juvenile Clams.
Apparently when it comes to a good feed, the Green Crabs are out-competing species that are native to the West Coast. As well DFO notes that the species is know to disrupt eelgrass beds, the productive habitat for many juvenile fish species.

Further research on the risks of the European Green Crab can be found from this research document prepared by DFO back in 2008.
