From the TAC an allowance is made to provide for recreational fishing, customary Maori uses and other sources of fishing-related mortality. The remainder is available to the commercial sector as the annual Total Allowable Commercial Catch (TACC). For example, if a quota owner owns 10% of the quota for a stock, and the TACC is set at 200 tonnes, that quota owner receives 20 tonnes of ACE. The quota owner may choose to fish the ACE or trade it.
