^ Total catch advice for 2027 relative to the advice for 2026 (20 432tonnes).
^^ The probability of SSB being below Blim in 2028. This probability relates to the short-term probability of SSB Lt Blim and is not comparable to the long-term probability of SSB Lt Blim tested in simulations when estimating fishing mortality reference points.
