*	“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 discard rate estimates for 2014-2016.
**	SSB 2019 relative to SSB 2018.
***	Total catch in 2018 relative to TAC in 2017 (1178t).
^	Total catch derived from the wanted catch and the unwanted catches ratio.
