Stock assessment and management of the SNA 1 stock would benefit from estimates of snapper year-class strength, before these fish recruit into the adult fished populations. A single-phase stratified-random beam trawl survey of the Hauraki Gulf (102 stations) returned an estimate of 10.69 million 2019-year-class recruits (CV 15.9%). A two-phase stratified random survey in East Northland (102 stations), returned an estimate of 634 000 recruits (CV 18.7%). These results demonstrate that beam trawl surveys have the potential to generate year class strength estimates for 0+ snapper.
