Symbol Footnotes
* SSB 2028 relative to SSB 2027 (10 801 t).
** Advice value for 2027 relative to the corresponding advice value for 2026 (0 t).
*** F multiplier that equates approximately to the cumulative substock advice, 8574 t (3717 t + 3264 t + 1593 t), when following the MSY approach for the Northwestern and Viking substocks and MSY approach with precautionary considerations for the Southern substock independently and equates to a total catch of 8574 t (3704 t + 4870 t + 0 t).
