The tenth acoustic survey of southern blue whiting (SBW) on the Campbell Island Rise was carried out from 28 August to 25 September 2011 (TAN1112). The estimate of adult SBW biomass was 103 346 t in the first snapshot and 132 897 t in the second snapshot, giving an average adult estimate of 118 122 t (c.v. 22%). Three spawning areas were detected, with most of the adult biomass in the eastern area.  The estimate of 2-year-old SBW suggested that the 2009 year-class is above average. Few 3-year-old fish (2008 year-class) were observed.
