To further improve compliance with conservation measures, Members are required to notify the CCAMLR Secretariat of the movements into, out of and between subareas and divisions of the Convention Area for their flagged vessels within 24 hours of a movement occurring. A vessel may also provide these reports directly to the CCAMLR Secretariat. This information is validated with Vessel Monitoring System (VMS) data that is also provided to the CCAMLR Secretariat by vessels operating inside the Convention Area. A List of vessel movements is made available to Contracting Parties.
