Symbol	Footnotes
*	For spring-spawning stocks, the SSB is calculated at spawning time (April). Thus, it is influenced by fisheries and natural mortality between 01 January and spawning time (April).
**	SSB (2028) relative to SSB (2027).
***	The advised catch for 2026 was 0tonnes.
^	Blim, BPA, and MSYBtrigger cannot be achieved in 2028, even with zero catch.
