An acoustic survey of spawning hoki abundance in Cook Strait was carried out from two industry vessels from 24 July to 2 September 2015. The average estimate of hoki abundance from five accepted snapshots (204 000 t, CV 33%) was 21% higher than the equivalent estimate from 2013. Priors on the acoustic survey proportionality constant q were re-evaluated for both the Cook Strait and west coast South Island survey time-series to reflect recent revisions to hoki target strength estimates.
