    This paper describes some of the planned updates to the 2019 integrated stock assessment for the Heard Island and McDonald Islands Patagonian toothfish (Dissostichus eleginoides) fishery in Division 58.5.2. These updates will include, inter alia, the estimation and inclusion of fishing mortality caused by longline gear loss, and an adjustment to the maturity function to be used in the assessment.
