Fisheries
Several species of wild crab are the subject of crab fisheries around the coasts of the British Isles. The most important are the brown crab or edible crab, Cancer pagurus (29,193 t), various swimming crabs (3,180 t), the spider crab Maja brachydactyla (1,565 t), the shore crab or green crab Carcinus maenas (553 t) and the velvet crab Necora puber (193 t). Around 77% of the catch is landed in the United Kingdom, 19% in Ireland, 4% in the Channel Islands, and 1% in the Isle of Man.
