Intended use of commercial catch 21 Prior to 2001, the majority of carpet shark taken was reported as landed – destination code L (see Table 1). Since 2001, the majority of the catch has been reported as discarded (destination code D). Landed catch (destination code L) includes whole carpet shark, it also includes a fisher’s estimate of greenweight for carpet shark which are finned and the trunks of the sharks returned to the sea. The increase in reported discarded catch may be due to several factors, including: changes to the requirements of catch landing returns, and improved data validation systems, both of which came into effect in 2001. 22 Given the lack of reliable data, it is difficult to ascertain whether reporting improvements fully explain the apparent recent increases of both carpet shark catch and the proportion of catch that is discarded.

Until 1998/99, the majority of the carpet shark not discarded was landed green (unprocessed). In recent years, however, most landed catch is finned (only the fins are retained, the trunk of the shark is returned to the sea). 24 The finning of sharks has increased in popularity internationally over recent years to satisfy demand from Asian markets. Since 2001/02 there has been an increasing trend for carpet shark to be processed as fins only (90% or more of reported landed catch since 2003/04). 28

However, recreationally-caught carpet sharks are probably unintended catch when targeting other species. There is no daily bag limit or size restriction placed on recreational catches of carpet shark. 26 It is probably reasonable to assume that any recreationally-caught carpet sharks will be returned to the sea. This species is very hardy and able to survive removal from the water for long periods, so their survival rate when returned to the sea is probably high. Customary fishery characteristics 27 Sharks are well known to be ‘taonga’ (treasures) to Māori. Traditionally, Māori people night-fished for a range of shark species, and shark products provided an important source of food and trade items. Many species of sharks are well defined within Māori myths and legends, and sharks commonly feature in the carvings of marae around New Zealand. The strength of sharks is often called upon in ritualised ceremonies, or by warriors heading into battle, or by people in distress at sea. 28 Customary shark fisheries no longer exist on the scale of the 19th century, although some North Island harbours still provide for some customary shark fishing. There is no information available on the quantities of carpet shark catch taken by customary fishers, either now, or in the past. 29
