This paper summarises catch, effort and fleet statistics for Australian tuna and billfish fisheri... more This paper summarises catch, effort and fleet statistics for Australian tuna and billfish fisheries operating in the Indian Ocean Tuna Commission (IOTC) area of competence in the 2002 calendar year, as well as providing some historical perspective on domestic catch and effort trends in this region. The predominant gear used by Australian vessels catching tuna and billfish in the IOTC area of competencewere longline and purse seine. Total longline effort in 2002 was 5.98 million hooks, down from more than 6.2 million hooks in 2001. The longline fishery targets swordfish (2000 mt in 2002), but also takes significant catches of yellowfin (354 mt), and bigeye (418 mt). Catches of swordfish and yellowfin were slightly lower than in 2001, but bigeye catches were slightly higher than in 2001 (385 mt). There were 40 domestic longliners fishing in this region in 2002, a decline from 50 vessels in 2000. The purse seine fishery targets southern bluefin tuna which are towed to cages near shore for fattening. Late season catches of skipjack are taken by purse seiners in some years. In 2002, 1144 mt of skipjack was caught by purse seine (up from 897 mt in 2001). Just over 5000 mt of southern bluefin has been caught and towed to fattening cages by domestic purse seiners in each of the past four years.
