    Abstract

    A survey of mackerel icefish, Champsocephalus gunnari, was undertaken in Division 58.5.2 in the vicinity of Heard Island in July 2008 to provide the information for an assessment of short-term annual yield in the 2008/2009 CCAMLR season. This paper provides a preliminary assessment of yield for the area of Division 58.5.2 to the west of 79o 20’ E using standard CCAMLR methods. The strong year class detected in last year’s survey is now fully recruited as the 2+ cohort, and dominates the population.
