Too big to be sustainable? - Managing supertrawlers

They have brought a version of a marine scorched-earth style of fishing to seas all around the world for many years. These vessels represent one of the most destructive interactions between commerce and the natural world.
This situation is exacerbated by the impression that efforts to police them are inadequate. The Irish Fish Producers’ Organisation (IFPO) argue that authorities are powerless to adequately monitor supertrawlers because of the European quota system and any vessel’s particular entitlements at any given moment. Their concerns seem motivated by the pressure of commercial competition rather than the impact these mega-trawlers have on precious fish stocks.
