Status of reporting of fisheries Statistics and data quality

The IOTC databases are under constant review. Each year, the IOTC Secretariat prepares reports on the status of fisheries for IOTC species, main trends, and main issues identified for each dataset and species for the Working Parties.

The IOTC Data Quality Catalogues represent an attempt by the IOTC Secretariat to assess the quality of the catch, effort and size frequency statistics for IOTC species in the IOTC databases. Please, note that the type of data that the IOTC Secretariat receives from CPCs and other Parties is aggregated, and this reduces the ability of the Secretariat to properly assess its quality.

Levels of compliance of IOTC CPCs and other parties with IOTC Requirements are assessed annually, through a report that the IOTC Secretariat prepares for the IOTC Working Party on Data Collection and Statistics, or the Scientific Committee (Report on IOTC Data Collection and Statistics).
