As per the attached note, we've confirmed that green crab are present in
Barkley Sound. At this time we are arranging for a general inspection of
the intertidal zone of Barkley Sound across the summer period, to assess
presence/absence on a broader geographic scale.
Additional information will be posted to the DFO web page, which will be
updated by Friday.

Subject: RE: British Columbia Carcinus Update
Folks: I would like to advise you all that the green crab, Carcinus maenas,
has now been found in British Columbia! A live 60 mm female crab was
collected at the head of Barkley Sound in Useless Inlet (48 degree, 59
minutes N; 125 degrees, 3 minutes W)on the west coast of Vancouver Island by
Cheryl Dunsmore at 10:00 am on June 17, 1999. It was found at the 0.3 m tide
level on the north end of the Imperial Eagle Clam Co. lease under a layer of
macroalgae. It likely arrived by larval transport, as there was no known
transport of live oysters, etc. to this site by anyone, ruling out possible
accidental introduction of juveniles or adults. The size of the specimen
suggests that it may have arrived a year or so ago, possibly as a result of
El Nino generated warm water intrusions from the south.
The site is a small inlet at the head of the sound, and is a site where
thermal stratification is more pronounced. The exotic bivalve Nuttalia
obscurata (varnish, or dark mahogany clam), introduced into the Strait of
Georgia around the early 1990s and now widespread there, had also
established itself at the head of Barkley Sound, with some specimens even
reported as far north as Nootka Sound.
