Symbol Footnotes
* Differences between the total catch and the sum of projected landings and discards result from rounding.
** Marketable landings.
*** Including BMS landings. assuming recent discard rate.
# Fprojected landings and Fprojected discards do not add up to Ftotal as they are calculated using different ages.
^ SSB 2023 relative to SSB 2022.
^^ Total catch in 2022 relative to the advice value 2021 and TAC (21 361 tonnes).
