Advice Sentence
*
ICES advises that when the maximum sustainable yield (MSY) approach is applied, catches in 2025 and 2026 should be no more than 4 821 and 4 637 tonnes, respectively. If the contribution of landings to dead catch does not change from 2023, this implies landings in 2025 and 2026 of no more than 3 784 and 3 639 tonnes, respectively.
