This document reports on a meeting held to discuss means of reducing discrepancies between tuna statistics held in different databases. The statistical system, i.e. methods of collection, analysis and dissemination of data of the various agencies were described and papers describing these are given as appendices to this report. The principal function of FAO, with regard to tuna statistics, was noted to be the provision of a global overview of world tuna production by species and by countries and it was agreed that in the performance of this function FAO could be much helped by close cooperation with the regional agencies. In turn, the agencies indicated their readiness to cooperate. To further this objective the agencies proposed an informal arrangement for the exchange of data and the holding of periodic inter-agency meetings to discuss problems which have arisen in the process and to further steps for the standardization of procedures for the collection of such data.
