Download FAR 2015/04 Acoustic survey of spawning hoki in Cook Strait and Pegasus Canyon during winter 2013

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.
