SSB 2027 relative to SSB 2026.
**
Advice value for 2026 relative to the corresponding 2025 value (5 116 tonnes).
^
The probability of SSB being below Blim in 2027. This probability relates to the short-term probability of SSB <; Blim and is not comparable to the long-term probability of SSB <; Blim tested in simulations when estimating fishing mortality reference points.
