Total catch advice for 2026 relative to the advice for 2025 (31 565tonnes).
^^
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.
