*
SSB 2028 relative to SSB 2027.
**
Advice value for 2027 relative to the corresponding 2026 value (5364 tonnes).
^
The probability of SSB being below Blim in 2028. This probability relates to the short-term probability of SSB <; Blim and is not comparable to the long-term probability of SSB <; Blim. Fishing mortalities less than FPA have been shown to have less than 5% probability of the stock being below Blim in the long term when tested through simulations when estimating fishing mortality reference points
^^
These options were left blank because they cannot be achieved in 2028, even with zero catch in 2027.
