Symbol Footnotes
* SSB corresponds to mid-May estimate, with 80% of the catch assumed to be taken in the first six months of the year (average percentage from 2021-2023).
** F (age 2).
*** SSB (2025) relative to SSB (2024).
^ Catch (2025) relative to the 2024 TAC (33000 tonnes).
^^ Advice for 2025 relative to advice for 2024 (33000tonnes).
^^^ The probability of SSB being below Blim in 2025. This probability relates to the short-term probability of SSB below Blim and is not comparable to the long-term probability of SSB below Blim tested in simulations when estimating fishing mortality reference points.
