Symbol Footnotes
* SSB 2027 relative to SSB 2026 (110427 tonnes).
** Total catch in 2026 relative to the catch advice value for 2025 (52466 tonnes).
*** The probability of SSB being below Blim in 2027 is zero for all catch scenarios except SSB(2027)=Blim, which is 50%. This probability relates to the short-term probability of SSB <; Blim and is not comparable to the long-term probability of SSB <; Blim tested in simulations when estimating fishing mortality reference points.
