Symbol	Footnotes
*	“Wanted catch” is used to describe fish that would be landed in the absence of the EU landing obligation. The “unwanted catch” refers to the component that was previously discarded.
**	Wanted catch in 2019 compared with the TAC of Subarea 6 (213 tonnes). Note the stock area is only Division 6.a.
***	SSB 2020 relative to SSB 2019.
^	The Blim, Bpa, and MSY Btrigger options were left blank because SSB2020 = Blim and SSB2020 = Bpa = MSY Btrigger cannot be achieved in 2020, even with zero catch advice.
^^	Advice value for 2019 relative to advice value for 2018. This is not provided because the advice in 2018 was zero.
