We provide a photographic reference set for Antarctic toothfish (Dissostichus mawsoni) from the Ross Sea region. The photographs were derived from the four otolith reference set blocks used by New Zealand with the “sister” otoliths provided to CCAMLR for use by other Members. Two photographs are provided for each otolith; one of the prepared otolith surface alone, and a second with symbols marking the location where each annulus was counted. The photographs link to an excel spreadsheet providing data on each otolith. We recommend that the CCAMLR Secretariat make this reference set available via the CCAMLR website for use by Members.
