Summary
Robust stock assessments and catch limits for Dissostichus mawsoni according to CCAMLR decision rules remain to be determined for Divisions 58.4.1 and 58.4.2. Precautionary management arrangements are in place as set out in Conservation Measures 41-11 and 41-05. WG-FSA-16/29, WG-FSA-18/59, WG-FSA-19/44, and SC-CAMLR-39/BG/10 outlined the multi-member toothfish exploratory fishery research plans for these Divisions, including the research objectives, methods, and milestones in accordance with ANNEX 24-01/A. In this paper we report on (1) exploratory fishing activities undertaken by Australia, France, Japan, the Republic of Korea, and Spain between the 2011/12 and 2020/21 fishing seasons (fishing seasons are hereafter abbreviated to the end year), as per Milestone 1.7 and (2) ageing of collected toothfish otoliths and updated estimation of biological parameters as per Milestone 1.8. The summaries provided herein were generated using an R-Markdown document that is available to Members to facilitate standardised reporting on data collection in CCAMLR’s Exploratory Fisheries.
