In 2015, there was sufficient information to report on the status of up to 183 stocks or sub-stocks out of a total of 377 significant stocks managed under New Zealand’s Quota Management System. The stocks with sufficient information to determine their status make up the majority of commercial landings.
Of 157 stocks or sub-stocks with known status relative to the soft limit (the lower bound on the desirable population size), 130 (82.8%) have been determined to be above the soft limit (i.e. NOT overfished) based on a recent assessment or evaluation. In terms of tonnage of landings, 96.8% of stocks of known status were above the soft limit in 2015.
In 2015, 27 stocks were considered to be overfished (below the soft limit): southern bluefin tuna, Pacific bluefin tuna and bigeye tuna (highly migratory species that are present seasonally in New Zealand waters), three stocks of black cardinalfish, five stocks of bluenose, four stocks or sub-stocks of orange roughy, three stocks or sub-stocks of snapper, two stocks or sub-stocks of John dory, two stocks or sub-stocks of scallops, and one stock or sub-stock each of flatfish, oyster, paua, pipi and freshwater eels.
Rebuilding programmes or Total Allowable Catch (TAC)/TACC reductions are in place in these fisheries to allow them to rebuild to target levels.
