Advice Sentence
*
ICES advises that when the maximum sustainable yield (MSY) approach is applied, landings in 2027 and 2028 should be no more than 7 337 and 6 559 tonnes, respectively. ICES cannot quantify the corresponding catches. Management of the catches of skates and rays under a combined total allowable catch (TAC) prevents effective control of single-stock exploitation rates and could lead to the overexploitation of some species
