Advice Sentence
*
ICES advises that when the precautionary approach is applied, and assuming that discard rates and fishery selection patterns do not change from the average of the years 2023–2025, catches in each of the years 2027 and 2028 should be no more than 23 tonnes. To ensure the stock in Functional Unit (FU) 10 is exploited sustainably, management should be implemented at the FU level. ICES notes the existence of a management plan, developed and adopted by one of the relevant management authorities for Subarea 4.
