Advice Sentence
*
ICES advises that when the MSY approach is applied, catches in 2024 should be no more than 2 367 tonnes. The use of a combined TAC for plaice in divisions 7.d and 7.e prevents effective control of single stock exploitation rates and could lead to the overexploitation of either stock. ICES advises that management should be implemented at the stock area level. ICES notes the existence of a precautionary management plan, developed and adopted by one of the relevant management authorities for this stock.

SSB 2025 relative to SSB 2024.
#
All plaice in Division 7.d, including plaice originating from the North Sea and the western English Channel. Of the plaice caught in Division 7.d, 12.49% is assumed to originate from the North Sea and 3.75% from the western English Channel, which are added to the predicted values for the Division 7.d plaice stock and applies to total catch, projected landings, and projected discards. Following ICES advice basis, catches in Division 7.d will comprise 2367 tonnes coming from the ple.27.7d stock, plus 352 tonnes coming from the ple.27.420 stock and 106 tonnes from the ple.27.7e stock.
##
Total catch of plaice in division 7d in 2024 relative to the advice value 2023 (5671 tonnes).
###
Bpa and MSY Btrigger cannot be achieved in 2025, even with zero catches.
^
Differences between total catch and the sum of projected landings and discards result from rounding.
