The Commission for the Conservation of Southern Bluefin Tuna was founded in 1994. The Commission has no specific area of jurisdiction. Instead, the Commission applies to southern bluefin tuna (Thunnus maccoyii – SBT) throughout its global distribution. CCSBT is recognized as having the principal SBT management role and therefore conducts the assessments and sets the conservation measures for SBT.
Science planning, execution, and analysis is primarily conducted by the Scientific Committee and Member States. CCSBT shares interest with several other RFMOs, namely WCPFC, IOTC and ICCAT.
CCSBT collects a variety of data types from its members and cooperating non-members, including total catch, catch and effort data, and catch at size data. Catch and trade information is also collected. CCSBT does not have a management area and has no mandate for managing species other than SBT, although the Commission has established a Working Group on Ecologically Related Species (ERSWG) and has taken measures to reduce the impact of SBT fishing on ecologically related species and bycatch.
