Summary of the toothfish fishery and tagging program in the Amundsen Sea region (SSRUs 882C–H) to 2019/20

The Amundsen Sea region toothfish fishery has been operating since 2003. Fishery catch showed a truncation of the right-hand limb of the age distribution between 2004 and 2014 with no further age data available after 2016. We recommend that further ageing of toothfish in the Amundsen Sea region be made a priority to develop annual age-length keys and age frequencies. We further recommend that catch limits in the Amundsen Sea region be calculated following the trend analysis rules developed by WG-FSA for research blocks (CAMLR-XXXVI 2017, Annex 7 paragraph 4.33).
