Using underwater video to evaluate the performance of the Fukui trap as a mitigation tool for the invasive European green crab () in Newfoundland, Canada.

The European green crab () is a destructive marine invader that was first discovered in Newfoundland waters in 2007 and has since become established in nearshore ecosystems on the south and west coast of the island. Targeted fishing programs aimed at removing green crabs from invaded Newfoundland ecosystems use Fukui traps, but the capture efficiency of these traps has not been previously assessed. We assessed Fukui traps using observation with underwater video cameras as they actively fished for green crabs.
