Advice Sentence
*
ICES advises that when the EU multiannual plan (MAP) for Western waters and adjacent waters is applied, catches in 2020 that correspond to the F ranges in the MAP are between 7070 tonnes and 10 377 tonnes. The entire range is considered precautionary when applying the ICES advice rule. To ensure that the stock in Functional Unit (FU) 15 is exploited sustainably, management should be implemented at the functional unit level.
