* Includes commercial landings and recreational removals.
** Assumed projections based on 2022-2025 proportions of partial F of commercial and recreational removals.
*** SSB2028 relative to SSB2027.
^ Advice value for 2027 relative to the advice value for 2026 (3310 tonnes).
^^ The probability of SSB being below Blim in 2028. This probability relates to the short-term probability of SSB less than Blim and is not comparable to the long-term probability of SSBless thanBlim tested in simulations when estimating fishing mortality reference points. Uncertainty of modelled recruitment in 2024 and 2025 is underestimated, which increases the uncertainty of the probability estimation.
^^^ The MSY Btrigger option was left blank because it cannot be achieved in 2028, even with zero catch in 2027.
