Advice Sentence
*
ICES advises that when the MSY approach is applied, catches in 2018 should be no more than 5445 tonnes. ICES advises, under precautionary considerations, that activities that have an impact on the spawning habitat of herring should not occur, unless the effects of these activities have been assessed and shown not to be detrimental.
