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 13 218 tonnes and 28 838 tonnes. According to the MAP, catches higher than those corresponding to FMSY (19 982 tonnes) can only be taken under conditions specified in the MAP, while the entire range is considered precautionary when applying the ICES advice rule. Management of catches of the two megrim species, L. whiffiagonis and L. boscii, under a combined species TAC prevents effective control of the single-species exploitation rates, and could lead to overexploitation of either species.
