New Zealand fisheries technical reportSummary: A joint Japan-New Zealand trawl survey was carried out in New Zealand Exclusive Economic Zone area D by Shinkai Maru from 22nd November to 12 December 1983. The 84 stratified random trawl stations provided stock size indices and distribution and biological data for the commercially important species, with those obtained on previous surveys. The standing stock sizes of hoki (454 300t) and hake (29 700t) were significantly lower than those estimated by the March 1983 survey of the same area. Possible explanations such as differences in gear operation and seasonal fish movements are discussed.
