    An age determination manual for Antarctic toothfish (Dissostichus mawsoni) was produced for CCAMLR in 2010. The manual has been updated to include the development and use of a reference set to provide training and refresher material for agers, and to formally track reader performance and reader drift. In addition, standardized analysis and data reporting are recommended to allow the evaluation of D. mawsoni aging data for use in stock assessment.
