Introduction

The IOTC reference data code lists are utilised to categorise and qualify the fisheries and biological datasets managed by the Indian Ocean Tuna Commission (IOTC), including those collected through the Regional Observer Scheme (ROS). The IOTC Reference Data Catalogue provides a comprehensive summary of all IOTC reference data code lists, organised by functional domain. The code lists are displayed in a paginated, searchable table format, with a brief description and an option to export each list as a CSV file for offline use. Each IOTC form used for reporting data to the IOTC includes URL links to the relevant code lists accompanying each dataset.
