Symbol Footnotes
* The probability of SSB being below Blim in 2028. This probability relates to the short-term probability of SSB <; Blim and is not comparable to the long-term probability of SSB <; Blim, fishing mortalities less than FPA have been shown to have less than 5% probability of the stock being below Blim in the long term when tested through simulations when estimating fishing mortality reference point.
** The probability is not exactly 0.50 because of the asymmetric error distribution.
# Includes commercial landings, recreational kept, commercial discards, and recreational dead released, computed assuming 5.00% post-release mortality.
## SSB 2028 relative to SSB 2027 (28 268 tonnes)
### Advice values for 2027 are relative to the corresponding 2026 values (FMSY 7 618 tonnes, FMSYlower 6 423 tonnes; all other values are relative to the FMSY scenario; for sea bass caught in divisions 8.a–b, they are relative to the corresponding 2026 values in the area 8.a–b (FMSY 6271 tonnes, FMSYlower 5286 tonnes); all other values are relative to the FMSY scenario for divisions 8.a and 8.b
^ EU multiannual plan (MAP) (EU, 2019).
^^ This scenario implies zero fishing in divisions 4.b–c, 7.a and 7.d–h in the third and the fourth quarter.
^^^ 0.1 means less than 1%
