Abstract
A combined trawl and acoustic survey of hoki, hake, ling, and associated species on the west coast South Island (WCSI) was carried out from 26 July to 23 August 2013. This was the tenth in a series of acoustic surveys of WCSI hoki spawning areas. The 2013 acoustic estimate was 13% lower than the equivalent index from 2012 and slightly below the long-term average of the time-series. The survey was also the third in a new time-series of trawl estimates for middle depth species from the WCSI.
