Invasion Description
1st record: Vancouver Island/British Columbia/Straits of Georgia (Quayle 1992)
Limnoria tripunctata in British Columbia is found mainly in oyster-growing areas, semi-enclosed coves, with limited wave action and warmer summer temperatures, but at least 5 occurrences happened in places with no history of oyster culture (Quayle 1992).
