21st Regular Session of the Scientific Committee

Agenda Item 4.5.2.1 Stock assessment of Southwest Pacific striped marlin

In 2024, SSP conducted an assessment of the Southwest Pacific striped marlin, highlighting serious concerns regarding the technical aspects of the assessment. Noting these concerns, SC20 recommended that further work, including resolving the conflict between the size composition data and the CPUE indices, should be undertaken as part of a revision to the assessment for consideration at SC21 (paras 248-249, SC20 Summary Report). SC21 will review the updated assessment conducted using the Stock Synthesis model and provide recommendations to the Commission. Future projection scenarios will be covered under the Management Issues theme.
