Advice Sentence
*
Please note: This advice was updated June 2019 (ICES, 2019) ICES advises that when the precautionary approach (PA) is applied, wanted catches in each of the years 2019 and 2020 should not exceed 1154 tonnes. ICES cannot quantify the corresponding total catches. To ensure that the stock in Functional Unit (FU) 33 is exploited sustainably, management should be implemented at the functional unit level.
