EU request to provide guidance on operational methods for the evaluation of the MSFD Criterion D3C3

To provide the requested guidance, ICES evaluated the proposed indicators for MSFD Criterion D3C3 of the size distribution of the stock, the selectivity pattern of the fishery, and the genetic effects of exploitation on the stock, concluding that the indicators are currently neither operational nor fit for the purpose of the assessment of good environmental status (GES). Consequently, ICES advises that these indicators should not be used until usable reference points have been developed.

Hence, ICES recommends that the assessment of GES for Descriptor D3 should focus on indicators for criteria D3C1 and D3C2.
