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