14 The total reported catch for each of the cited fishing years is shown in the following table. 2002/03 2003/04 2004/05 2005/06 2006/07 656 t 695 t 684 t 606 t 485 t 15 The percentage of total reported catch for each fishing year discarded or landed is shown in the following table. 2002/03 2003/04 2004/05 2005/06 2006/07 Discarded 46% 48% 30% 33% 27% Landed 54% 51% 69% 67% 73% 16 The percentage of reported landed catch for each fishing year landed as dressed, green, or meal is shown in the following table (assuming discarded catch is reported as green). 2002/03 2003/04 2004/05 2005/06 2006/07 Dressed 41% 32% 37% 30% 31% Headed and gutted 6% 3% 3% 3% 3% Green 46% 49% 31% 33% 27% Meal 0% 13% 19% 28% 26% Livers 7% 2% 10% 6% 13% 17 Although almost 40 target fisheries report seal shark as bycatch, the ling, hoki and orange roughy target fisheries dominate the estimated catch of seal shark (35%, 27% and 17% respectively over the last 5 years). Targeted fishing accounted for 10% of the estimated seal shark catch in 2004/05 but averages less than 2.5% over the last five fishing years and in 2006/07 accounted for only 0.25%. 18 Seal shark is taken by several methods. The percentage of estimated catch of seal shark taken by the various methods is shown in the table below. The majority is taken by bottom trawl and set net. Method 2002/03 2003/04 2004/05 2005/06 2006/07 Bottom longline 6.8% 9.0% 10.2% 15.1% 15.6% Bottom trawl 52.0% 56.2% 39.7% 49.5% 53.8% Crab potting - - - - 0.2% Drop / dahn lines 0.4% 0.3% 0.3% 0.5% 0.2% Midwater trawl 0.3% 1.3% 1.1% 1.1% 2.3% Set net 39.4% 33.1% 48.6% 33.8% 28.0% Trot line 1.2% 0.1% - - - 19 In the last decade, seal shark has become an important bycatch species, more recently marketed for its flesh. The estimated commercial catch of seal shark increased from 1989-90 through 2004-05 and has decreased in the last two years. This may reflect changes in stock abundance, or alternatively, changes in reporting of seal shark 68
catches. The reported discards have decreased as a percentage of reported catch and approximately 75% is now landed, indicating some level of market interest. Recreational fishery characteristics 20 MFish has no information on recreational catch of seal shark. Due to the offshore location and depth distribution of this species, recreational catch is likely to be negligible. Customary fishery characteristics 21 MFish has no information on customary catch of seal shark. Due to the offshore location and depth distribution of this species, customary catch is likely to be negligible. Management Existing management information 22 Seal shark is currently managed as an open access, non-QMS fishery Provisional catch history implications 23 Seal shark is a Schedule 4D stock. If introduced into the QMS before 1 October 2009 quota allocation will be by way of provisional catch history. International obligations 24 There are no international obligations specific to seal shark. Treaty settlement obligations 25 MFish is undertaking research to provide information on the traditional and customary factors that may need to be considered in the management decision-making process. Currently there is no information specific to seal shark. 69
