The 13th acoustic survey of southern blue whiting (SBW) on the Campbell Island Rise took place from 28 August to 25 September 2019 aboard RV Tangaroa. Two acoustic snapshots were completed, both detecting three spawning aggregations in the survey area. Observer data collected from the commercial fleet showed spawning occurred from 3–18 September, and from 23–30 September. The biomass estimate of adult SBW was 91 145 t (CV 27%), 6% lower than that from the previous survey in 2016 (97 117 t).
