      1     Opening of the meeting

      The Convener will welcome participants, outline priorities for the meeting and provide an overview of local facilities including Secretariat support, Internet access and extracurricular activities.

      2     Calibration of echosounders
      3     Methods for the collection and analysis of krill acoustic data from fishing vessels

      SG-ASAM will review the methods for processing acoustic data collected on krill fishing vessels according to the swarm-based approach agreed at SG-ASAM-17, including validations/potential improvements.

      4     Analysis of data collected from fishing vessels
      6     Other business

      SG-ASAM will review other relevant issues.

      7     Advice to the Scientific Committee
      8     Adoption of the report and close of the meeting.
