    Resumen

    The annual Random Stratified Trawl Survey was undertaken in Division 58.5.2 in the vicinity of Heard Island during April 2016. This paper provides a preliminary assessment of mackerel icefish population structure, abundance and yield for the area of Division 58.5.2 to the west of 79o 20’ E using standard CCAMLR methods (CMIX and Generalized Yield Model). A large 2+ cohort is dominating the population. These projections indicate that catches of 561 t in the 2016/17 season and 402 t in the 2017/18 season satisfy the CCAMLR decision rules.
