# 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, 12.69% are assumed to originate from the North Sea and 3.81% from the western English Channel (average ratio calculated over the years 2003–2023). 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 2600 tonnes coming from the ple.27.7d stock, plus 395 tonnes coming from the ple.27.420 stock and 119 tonnes from the ple.27.7e stock.
## Projected catch of plaice caught in division 7d in 2025 relative to the advice value 2024 (2826tonnes).
### Projected catch of plaice caught in division 7d in 2025 relative to the TAC in 2024 (2826tonnes).
^ Differences between total projected catch and the sum of projected landings and discards result from rounding.
^^ Projected catch of plaice caught in Division 7d in 2025 relative to the ICES estimates of catches in 2023 (3812tonnes).
^^^ Bpa and MSY Btrigger cannot be achieved in 2026, even with zero catches.
