Provide the Working Party on Tropical Tunas (WPTT) with a review of the status of the information available on tropical tunas in the databases at the IOTC Secretariat as of September 2020, as well as a range of fishery indicators, including catch and effort trends for fisheries catching tropical tunas in the IOTC area of competence. It covers data on nominal catches (retained and discards), catch-and-effort, size-frequency and other data, including release and recapture (tagging).
Prior to each WPTT meeting the IOTC Secretariat develops a series of tables, figures, and maps that highlight historical and emerging trends in the fisheries data held by the IOTC Secretariat. This information is used during each WPTT meeting to inform discussions around stock status and in developing advice to the Scientific Committee.
This document summarises the standing of a range of information received for the tropical tuna species under the IOTC Mandate, in accordance with IOTC Resolution 15/02 Mandatory statistical requirements for IOTC Members and Cooperating Non-Contracting Parties (CPCs)[1], for the period 1950–2019.
The document also provides summaries of any important reviews to series of historical catches for tropical tunas and a range of fishery indicators, including catch and effort trends, for fisheries catching tropical tunas in the IOTC area of competence.
