    This document summarizes the method used to link releases and recaptures of tagged toothfish and skates in the Convention Area, and the current state of the database of linked tags held by the CCAMLR Secretariat. Thanks to improvements in data quality and the growing use of CCAMLR tags by Members, the quality of links has increased with time. To date, over 98% of recaptured fish have been linked to their release event, with most lower quality links occurring prior to 2006. We make recommendations to improve data quality in high priority areas and years, to move towards a centralized tagging programme, and to use future iterations of this report to better understand toothfish and skate spatial ecology.
