Advice Sentence
*
ICES advises that when the maximum sustainable yield (MSY) approach is applied, total removals in 2027 should be no more than 209 tonnes. This applies to the sum of the commercial and recreational catches (accounting for survival of released fish).

^^
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.
