Abstract
 The 21st acoustic survey of spawning hoki abundance in Cook Strait was carried out from Kaharoa from 17 July to 28 August 2019 (KAH1904). The acoustic survey also covered the other major eastern spawning areas off the east coast South Island. The acoustic abundance index from the 7 snapshots in Cook Strait in 2019 was 91 000 t, which was 11% lower than the equivalent index from the 2017 survey, and the lowest since 2008. Aggregations of hoki also occurred in Pegasus Canyon.
