Lobsters are mostly fished using lobster pots , although lines baited with octopus or cuttlefish sometimes succeed in tempting them out , to allow them to be caught in a net or by hand . In 2008 , 4 @,@ 386 t of H. gammarus were caught across Europe and North Africa , of which 3 @,@ 462 t ( 79 % ) was caught in the British Isles ( including the Channel Islands ) . The minimum landing size for H. gammarus is a carapace length of 87 mm ( 3 @.@ 4 in ) .
