Key points: 2021 stock assessment outcomes • The West Coast Demersal Scalefish Resource (WCDSR) is halfway into a 20-year recovery plan following a period of overfishing in the 1990s and 2000s. • This latest assessment provides an important “health check” on the recovery status. • The recovery plan is based on maintaining recreational (including charter) and commercial sector’s total fishing mortality below catch limits and protecting key spawning aggregations to recover the WCDSR by 2030. • The Department of Primary Industries and Regional Development (DPIRD) tracks recovery progress by undertaking weight of evidence stock assessments of WCDSR indicator species dhufish and pink snapper every 3-5 years. • The latest science shows that further management action is required to allow the WCDSR to recover by 2030. • The current management arrangements have successfully halted the decline in spawning biomass of indicator species dhufish and pink snapper but there has been limited recovery of these species. • Fishing pressure is still too high as there continues to be a lack of older dhufish and pink snapper in the population. • This science update follows on from the previous WCDSR research update in December 2019. Detailed information on the latest stock assessment is available in Fisheries Research Report No.316.
