Second Science Management Dialogue
Agenda Item 5. Development of Bigeye and Yellowfin TRPs
According to the Indicative Work Plan for the Adoption of Harvest Strategies under CMM 2022-03 (Attachment 4, WCPFC20 Summary Report), the Commission is anticipated to agree on TRPs for bigeye tuna and yellowfin tuna in 2024.
The SSP presented SC20-MI-WP-07 (Analyses to Inform Discussions on Candidate Bigeye and Yellowfin Target Reference Points) at SC20, which updates the analyses previously presented to WCPFC18 using the latest assessments for these stocks. SC20 noted that based upon these analyses, current objectives for these species cannot be simultaneously met.
SC20 recommended updating SC20-MI-WP-07 for the Commission by including the depletion levels for South Pacific albacore resulting under each candidate TRP level, and assessing the impact on vulnerable biomass for bigeye and yellowfin tuna in tropical and southern longline fisheries. Additionally, SC20 advised re-evaluating bigeye and yellowfin tuna TRPs incorporating recent fishing levels from Indonesia, Philippines, and Vietnam.
SMD02 will offer advice to the Commission for the adoption of these TRPs for bigeye and yellowfin tuna.
