A survey of Patagonian toothfish, Dissostichus eleginoides,was undertaken in Division 58.5.2 in the vicinity of Heard Island in May 2004 to provide the information for an assessment of short-term annual yield in the 2004/2005 CCAMLR season. This paper provides a preliminary assessment of yield for the area of Division 58.5.2 to the west of 79 o 20’ E using standard CCAMLR methods. It presents a range of sensitivity analysis for the assessment based on deliberations at WG-FSA 2003 with respect to the surveys and ages included in the estimation of the recruitment series.
