Symbol Footnotes
* Marketable landings.
** Including BMS landings. assuming recent discard rate.
*** SSB 2022 relative to SSB 2021.
# Other scenarios do not include FMSYupper because SSB (2021) is less than MSYBtrigger.
## Bpa and Btrigger cannot be achieved in 2022. even with zero catches.
^ Catch in 2021 relative to TAC in 2020: North Sea (14718t)+Skagerrak (2103t) + eastern English Channel (858t)= 17679t.
^^ Total catch 2021 relative to advice value 2020 (13686t).
