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.
# EU multiannual plan (MAP) for the North Sea (EU, 2018).
## Fprojected landings and Fprojected discards do not sum up to Ftotal as they are calculated using different ages.
