Symbol Footnotes
* Including BMS landings, assuming recent discard rates (i.e., 2023–2025).
** Fprojected landings and Fprojected discards do not add up to the Ftotal, as they are calculated using different ages.
*** SSB 2028 relative to SSB 2027.
# This scenario implies zero fishing in Division 7.d in the first quarter.
^ Projected catch of plaice stock in 2027 relative to the advised value for 2026, adding the proportion caught in Division 7.d (163 951 + 179 = 164 129 tonnes).
^^ Projected catches for plaice caught in Subarea 4 and Subdivision 20 in 2027 are calculated as the total catch advice for the stock (160 380 tonnes) reduced by the projected catch of the ple.27.420 stock to be taken in Division7.d when fishing at catch advice level (39 tonnes landing + 135 tonnes discards).
^^^ Projected catch of plaice caught in Subarea 4 and Subdivision 20 in 2027 relative to the corresponding value in 2026 and to the 2026 TAC for Subarea 4 and Subdivision 20 (both 163 951 tonnes).
