Symbol Footnotes
* Differences between the total catch and the sum of projected landings and discards result from rounding.
** Including below minimum size (BMS) landings. Assuming average estimated discard rate by age 2021–2023.
# Fprojected landings and Fprojected discards do not add up to Ftotal, as they are calculated using different ages.
^ SSB 2026 relative to SSB 2025.
^^ Total catch in 2025 relative to the advice value 2024 and TAC (both 3675tonnes).
