 The 14th acoustic survey of the southern blue whiting stock (SBW) off Campbell Island (SBW 6I) was carried out onboard RV Tangaroa between 28 August and 23 September 2022. Thirteen (snapshot 1) and ten (snapshot 2) strata were surveyed and twelve research mark identification trawls were completed during the survey. Estimates of biomass of adult SBW were slightly higher than the equivalent estimate from 2019. The average estimate of biomass of juvenile SBW was the highest in the time series.
