Symbol Footnotes
* SSB 2027 relative to SSB 2026.
# The probability of SSB being below Blim in 2027. 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
^ Advice value for 2026 relative to the advice value for 2025 (4644tonnes).
^^ EU multiannual plan (MAP) for the Western Waters (EU, 2019).
^^^ These options were left blank because they cannot be achieved in 2027, even with zero catch in 2026.
