# 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, 13.08% are assumed to originate from the North Sea and 3.92% from the western English Channel (average ratio calculated over the years 2003–2025). 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 1102 tonnes coming from the ple.27.7d stock, plus 174 tonnes coming from the ple.27.420 stock and 52 tonnes from the ple.27.7e stock
## Projected catch of plaice caught in division 7d in 2027 relative to the advice value and the TAC in 2026 (both 1384tonnes).
^ Projected catch of plaice caught in Division 7d in 2027 relative to the ICES estimates of catches in 2025 (2314tonnes).
^^ Bpa and MSY Btrigger cannot be achieved in 2028, even with zero catches.
^^^ P(SSB(2027)) below Blim = 5% cannot be achieved in 2027, even with zero catches.
$ Total advised catch of plaice stock in 2027 relative to the advice value 2026 (1151tonnes).
