* SSB 2020 relative to SSB 2019.
** Catches in 2019 relative to sum of autonomous quotas in 2018 (304 900 tonnes; EU quota of 262 300 tonnes and Russian quota of 42 600 tonnes).
*** Advice value 2019 relative to advice value 2018 (291 715 t).
^ Advice value compared with last year catches resulting from MAP FMSY lower (219 152) and MAP FMSY upper (301 722 t), (in %Advice change*** column)
^^ MAP multiannual plan (EU, 2016).
^^^ F2018 is slightly higher than 0.26; therefore, the catch scenario differs slightly from the one for FMSY.
