Abstract

The annual random stratified trawl survey was undertaken in Division 58.5.2 in the vicinity of Heard Island and McDonald Islands during April 2019. Based on data from this survey, this paper provides a preliminary assessment for mackerel icefish (Champsocephalus gunnari) population structure, abundance and yield in Division 58.5.2 to the west of 79o 20’ E using standard CCAMLR methods (CMIX and Generalized Yield Model).The 2019 survey showed a large 2+ and 3+ cohort in the population. Catches of 527 t in the 2019/20 season and 406 t in the 2020/21 season, respectively, satisfied the CCAMLR decision rules.
