Report - Fisheries Assessment Report (FAR)
Abundance of spawning southern blue whiting at the Bounty Platform, southeast of New Zealand, was estimated by an acoustic survey from the fishing vessel Tomi Maru 87. Two surveys (snapshots) were carried out overnight on 18–19 and 20–21 August 2023. The estimated biomass in 2023 was 62% higher than that from the previous acoustic survey in 2017. Data on the size distribution of the fish, collected by Fisheries New Zealand observers, and fish age data indicate that most adult size fish were from the 2012 and 2018 year classes.
