CONSIDERING that the Customs Information System created by virtue of the Convention on the use of information technology for customs purposes fn permits the entry of personal data exclusively for the purpose of sighting and reporting, discreet surveillance or specific checks (Article 5 of the Convention), and that for any additional purposes a supplementary legal basis must be established,

ICCAT has adopted a number of recommendations creating control and surveillance obligations, notably on the establishment and transmission of statistics, inspection in port, vessel surveillance by satellite, vessel observations and transhipments, and checks on non-contracting parties and on stateless vessels.
