Symbol Footnotes
# Fwanted and Funwanted do not sum up to the Ftotal as they are calculated using different ages.
* Differences between the total catch and the sum of wanted and unwanted catches result from rounding.
** “Wanted” and “unwanted” catch are used to describe fish that would be landed and discarded in the absence of the EU landing obligation, based on average discard rate estimates for 2016–2018. * SSB 2021 relative to SSB 2020.
^ Total catch in 2020 relative to TAC in 2019 (12 555 tonnes).
^^ Total catch in 2020 relative to advice value 2019 (12 801 tonnes).
^^^ EU multiannual plan (MAP) for the North Sea (EU, 2018).
