    Abstract

    This paper presents the data and assessment approach for the revised stock assessment for Patagonian toothfish, Dissostichus eleginoides, at Heard Island and the McDonald Islands (HIMI) in CCAMLR Division 58.5.2. Since the last assessment in 2013, an extensive program for ageing otoliths has been launched, length-at-age has been re-estimated, and research into tag-recapture data has started. We have therefore made substantive progress in addressing the main points raised during WG-FSA 2013 for the next stock assessment.
