A fishery characterisation has been undertaken for SCI 4A. Catches have historically been intermittent, but increased rapidly after 2010, and have fluctuated around the TACC since 2014. Catches have predominantly been taken from a distinct area to the north of the Chatham Islands, with fishing in another area to the west for a short period during the mid 2000s. Standardised CPUE indices follow trends observed in raw CPUE data and scampi catches from the Chatham Rise middle depths trawl survey.
