Evaluating transfers of harvested shellfish products, from the west to the east coast of Vancouver Island, as a potential vector for European green crabs (Carcinus maenas) and other non-indigenous invertebrate species: Fs70-6/2015-016E-PDF

The transfer of shellfish (clams, oysters, and mussels) from NIS-infested areas is a vector for both mobile (e.g. Green Crabs) and sessile (e.g. tunicates/bryozoans) NIS. This is true regardless of the harvest type or intended end-use (e.g. commercial culture, wild harvest, or monitoring programs). Green Crabs were entrained on all three shellfish species examined. Three tunicate and two bryozoan NIS were also entrained in most of the cultured shellfish species examined. Additional species entrained included native fish, non-cultured bivalves, crabs, shrimp, macrophytes (seaweeds, seagrasses, and algae), and snails (among many others).
