Download AEBR 122 Analysis of New Zealand’s Trawl Grounds for Key Middle depths and Deepwater Tier 1 Fisheries

We present an analysis of TCEPR bottom trawl data for trawls targeting the Tier 1 species (hake, hoki, jack mackerel, ling, orange roughy, oreo-dory, scampi, southern blue whiting, squid from the deepwater fish plan) between 1989–90 and 2008–09. We compare each trawl footprint with the relevant NABIS ranges and the footprint for all tier 1 species with the BOMEC. On average, 88.9% of the BOMEC cells have seen no trawling between 1989–90 and 2008–09, with 98.6% in 2008–09.
