Southern calamary Performance indicators • Catch and effort were higher than the reference levels and therefore exceeded reference points for the eighth consecutive year. The Statewide catch of 40 tonnes represented a 65% reduction compared with the previous year and therefore exceeded the rate of change reference point. • Catch rates were within reference levels. Resource status • There is a high degree of uncertainty about stock status. Management advice • Extended closure of the major spawning grounds appears to be effective in protecting the main (known) spawning event. Recent studies have confirmed that Great Oyster Bay represents a significance population source of calamary for southeastern Tasmania and thereby the importance of ensuring high levels of egg production from this region. The fishery for southern calamary expanded markedly in 1998/99 and, reflecting the development of this as a target fishery, subsequent catches have exceeded those for the reference period. After years of generally increasing catches, the 2005/06 catch of 40 tonnes represented a 65% decline compared with 2004/05. Declines in production were reported in all areas, not just those areas subject to the 3-month closure, i.e. Great Oyster Bay and Mercury Passage. The extension of closure to include a larger area of the east coast and changed timing will have contributed to the decline in production in 2005/06, but is unlikely to have been the sole contributing factor. Trends in effort were consistent with the pattern observed for catches. Statewide catch rates also decreased slightly, but were within reference levels during 2005/06.

Fisheries Research Report [Western Australia] No. 253, overall stock to begin at the Bioregion level. An overall estimate of SPR for the WCB was not produced for P. auratus as its biology differs substantially among management areas. • While there was evidence of recovery of P. auratus stocks at the bioregion level, the estimate of F in 2008/09-2010/11 was higher than that for G. hebraicum and much higher in the northern half of the WCB than the southern half. • The P. auratus stock in the WCB has begun to recover. However, as for G. hebraicum, it has not yet recovered to acceptable levels. Stock assessment results for Choerodon rubescens • The most recent estimates of commercial catch of C. rubescens were approximately equivalent to the catch benchmark but recreational catches were slightly greater.

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.
