Download FAR 2019/19: Trawl and acoustic survey of hoki and middle depth fish abundance on the west coast South Island, July–August 2018 (TAN1807)

A trawl and acoustic survey of the west coast South Island (WCSI) was carried out from 26 July to 8 August 2018, with 57 successful random trawl survey tows and two acoustic snapshots. The trawl estimate of ling abundance in 2018 was very similar to that from the most recent survey in 2016. The estimate for hake increased by 57% from 2016, but was still lower than the levels observed in 2012 and 2013. Acoustic estimates of hoki abundance were the lowest in that time-series, going back to 1988.
