** SSB 2028 relative to SSB 2027.
*** Total advised catch 2027 relative to the TAC value 2026 in Subarea 4 and part of the Division7.b-k TAC allocated to Division 7.d (198 609 tonnes; EU, 2026)
^ Total advised catch 2027 relative to the advice value 2026 (198 609 tonnes).
^^ The probability of SSB being below Blim in 2028. This probability relates to the short-term probability of SSB less than Blim and is not comparable to the long-term probability of SSB less than Blim tested in simulations when estimating fishing mortality reference points.
