Fprojected landings and Fprojected discards do not add up to the Ftotal, as they are calculated using different ages.

#
Projected catch of plaice caught in Subarea 4 and Subdivision 20 in 2025 relative to the 2024 TAC (154 663 tonnes) for Subarea 4 and Subdivision 20.
##
This scenario implies zero fishing in Division 7.d in the first quarter.
^
Projected catch of plaice stock in 2025 relative to the advised value for 2024, adding the proportion caught in Division 7.d (154 663 + 352 = 155 015 tonnes).
^^
Projected catches for plaice caught in Subarea 4 and Subdivision 20 in 2025 are calculated as the total catch for the stock (176 988 tonnes) reduced by the catch of the ple.27.420 stock to be taken in Division7.d when fishing at catch advice level (144 tonnes landing + 251 tonnes discards).

Projected catch of plaice caught in Subarea 4 and Subdivision 20 in 2025 relative to the value in 2024 (154 663 tonnes).
