Skull Island Tiger Prawns (Penaeus esculentus and Penaeus semisulcatus), also referred to as Skullies are caught in the Gulf of Carpentaria and are the biggest prawns in Australia. These prawns are harvested by a fleet of ten prawn trawlers with a crew of 5-7 per boat that operate off the north coast of Australia. These prawn trawlers range between 22m and 25m in length. This fishery is MSC Certified Sustainable and the first ever fishery to be government certified under a Carbon Neutral Program. The fishery was established in the late 1960’s and is Australia’s most valuable fishery managed by the Australian Commonwealth Government. The fishermen are members of the Northern Prawn Fishery Management Advisory Committee (NORMAC), which is an advisory body to the Australian Fisheries Management Authority (AFMA). NORMAC is dedicated to maintaining the sustainability of the Northern Prawn Fishery and has a strong history in the area of responsible and pro-active action in fisheries management.
