This report summarises the characterisation of one of the five main ling stocks managed under the Quota Management System: the ling stock off the west coast of the South Island (LIN 7WC), up to and including December 2025.
Both the ling Total Allowable Commercial Catch (TACC) and catches have been stable in most Quota Management Areas (QMAs) recently. Recent catches of ling in LIN 7 were close to the TACC.
Biological relationships were updated using the latest data available. Maturity has been variable in recent years.
The standardised catch per unit effort (CPUE) indices and the trawl survey biomass index all showed similar patterns from 2000, with a continued decline from 2012.
