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 1131 tonnes and 1150 tonnes. The entire range is considered precautionary when applying the ICES advice rule. To ensure that the stock in functional units 20 and 21 is exploited sustainably, management should be implemented at the level of the combined functional units 20 and 21.
