First Bigeye Management Workshop

The BMW will focus on finalizing the target reference points (TRPs) for bigeye tuna by evaluating the three specific candidates identified at WCPFC21, which are based on the 2012–2015 average spawning biomass depletion level: 

1. A baseline TRP (estimated at 34% SBF=0 under the 2023 assessment); 

2. A lower depletion / higher biomass option representing a 1.06 multiplier of the baseline (36% SBF=0);and

3. A higher depletion option representing a 0.94 multiplier of the baseline (32% SBF=0). 

Central to this discussion will be the management clarification of whether these levels should function as "targets" to be achieved on average or as "thresholds" for the stock biomass depletion to be maintained above with a higher specified probability, ensuring the selected strategy aligns with the Commission’s long-term sustainability and stability objectives.

Decision points

• Whether the defined bigeye TRPs are actual targets or are to be considered as thresholds.

• If the bigeye TRPs are to be considered as thresholds, specify the probability that the spawning biomass depletion should be maintained above the thresholds.
