Bottom trawling, possibly the most destructive fishing method yet devised by man, is to be regulated across the whole North Atlantic ocean. The process, which involves dragging nets weight down by metal girders across the seabed, is notorious for its wastefulness. Besides legitimate target species such as cod, plaice and sole, vast quantities of corals, sponges and other deep sea creatures are destroyed as bycatch. The devastation caused is so great that Greenpeace has been calling for some time for a moritorium (suspension of activity) on bottom trawling. Now it looks as though some progress may be being made.
