CRA5 Fishery Management and Statistical Areas
The CRA 5 fishery extends from the western side of the Marlborough Sounds across to Cape Jackson and then southwards to Banks Peninsula. There are three distinct regions of commercial fishing — Picton/Port Underwood, Ward-Kaikoura-Motunau, and Banks Peninsula, although a small number of commercial vessels work the area from Nelson through to D’Urville Island. The bulk of the commercial catch is taken from the area bounded by Tory Channel in the north and Motunau in the south.
In 2010 a single-stock version of the multi-stock length-based model (MSLM) (Haist et al. 2009) was fitted to two series of CRA 5 catch rate indices from different periods, and to size frequency, puerulus settlement and tagging data. This model was fitted to historical catch per day, daily CPUE, size data from market sampling, voluntary logbooks and observer catch sampling, tag-recapture data and a pre-recruit index from voluntary logbook data. Changes in MLS and selectivity caused by escape gap regulations were taken into account.
The TAC is set at 467 tonnes. 40 tonnes is allowed for amateur catch and 40 tonnes for customary catch. The TACC is 350 tonnes. The allowance for illegal unreported removals is 37 tonnes.
The preferred methods for amateur fishing are potting and diving with UBA. Recreational rock lobster fishing and the dive charter industry are both growing in the region. Dive clubs in the region have previously reported tag recapture.
There are 41 quota share owners in CRA 5. The fleet comprised 25 vessels reporting catch in 2012. Many commercial vessels work off beaches between Port Underwood and Motunau. The landed value of the commercial catch is estimated at $26 million in 2013/14 (based on average port price paid to fishermen), and the fishery supports processing and export facilities in Ward, Kaikoura, Wellington and Christchurch.
The CRA 5 industry members, through membership of their commercial stakeholder group CRAMAC 5, have encouraged and facilitated an ongoing dialogue with amateur fishing and dive clubs and with Iwi groups in the region. The responses to the process have been extremely encouraging in terms of future co-operative research and management initiatives.
CRA 5 has an intensive stock-monitoring regime in place. Intensive catch sampling and tag and release projects have been done as sub-contracted research services, and CRAMAC 5 operates an extensive Vessel Logbook programme that provides data to the stock assessment process. Similar levels of stock monitoring are confirmed through to 2015.
