Symbol Footnotes
* Including below minimum size (BMS) landings, assuming recent discard rate.
** 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.
# All plaice caught in Division 7.d, including plaice originating from the North Sea and the western English Channel. Of the plaice caught in Division 7.d, 12.86% are assumed to originate from the North Sea and 3.86% from the western English Channel (average ratio calculated over the years 2003–2024). Both of these predicted catches are added to the predicted values for the ple.27.7d stock and applied to projected catch, projected landings, and projected discards. Following ICES advice basis, catches in Division 7.d will comprise 1 151 tonnes coming from the ple.27.7d stock, plus 178 tonnes coming from the ple.27.420 stock and 53 tonnes from the ple.27.7e stock.
## Projected catch of plaice caught in Division 7.d in 2026 relative to the advice value and the TAC in 2025 (both 3 113 tonnes).
^ Projected catch of plaice caught in Division 7d in 2026 relative to the ICES estimates of catches in 2024 (2 088tonnes).
^^ BPA and MSY Btrigger cannot be achieved in 2027, even with zero catches.
$ Total advised catch of plaice stock in 2026 relative to the advice value 2025 (2 600tonnes).
