Abstract
An acoustic survey of spawning hoki abundance in Cook Strait was carried out using two industry vessels from 21 July to 3 September 2013. Seven of the nine completed Cook Strait snapshots met all the pre-survey criteria for estimating hoki abundance. The average hoki abundance estimate in 2013 was 377 000 t – 20% higher than the equivalent estimate from 2011. A single snapshot of Pegasus Canyon on 20 August 2013 gave an estimated abundance for this area of 134 000 t.
