Symbol Footnotes
* Marketable landings, assuming recent discard rate.
** Including below minimum size (BMS) landings (EU stocks), assuming recent discard rate, including surviving discards.
*** SSB 2027 relative to SSB 2026.
Note that the discrepancy between the scenario targeted catch and the actual change in catch are due to the 20% increase being applied to forecasts of landings and dead discards, only. Surviving discards are subsequently calculated from these forecasts.
^ Advice value for 2026 relative to advice value for 2025 (25 365 tonnes; advice for 2025 was summed from the advice for the two stocks merged during the recent benchmark [ICES, 2025a]).
^^ Note that, under the current stock conditions, the target SSB of these scenarios are not achievable within the limits of fishing pressure used in the forecasting procedure.
^^^ 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
