Presentation of GFCM work relevant to the MSFD (Miquel Bernal) 5. Preparation and agreement of commercial fin- and shellfish stocks to be assessed: o How to assess international stocks and those under national
jurisdiction? 6. Descriptor 3, Criterion 3.3 7. Way forward, Guideline completion and other recommendations Item 1 - Purpose The group will explore a common approach for the assessment of Descriptor 3 in the four MSFD marine regions. The group will consider gaps and recommendations and draft an annotated Table of Contents for a Guidance document.
The group will make recommendations for the further preparation of the Guidance document. Chair and facilitators at ICES WKD3R Doc. 1 Doc. 2

D3 assessment and DLS Important to: o Build on existing/available data o Proxies will be developed/used as an interpretation of what relates to MSY ICES concept of target categories o Recognises economic constraints on data
o Continue development of policy-relevant approaches for DLS BMSY and the potential for conflict ICES has refrained from using any BMSY value as a reference point and focused on FMSY and a biomass safeguard for scientific quota advice (CFP): o Lower bound of biomass variability as a safety measure rather than a constant rebuilding target (MSFD)
This reflects that biomasses are variable, influenced by fishing mortality but not directly managed by fisheries measures, and that an equilibrium BMSY may not make sense as a specific target or limit for policy. In the MSFD Descriptor 3 development, this has created a dilemma as BMSY is stated as an objective. Step 4 Overall status

Presentation of results Easily understandable way: o Regional maps with circles o Tabular format o Pie charts Future collaboration Annual evaluation of the international commercial fish and shellfish stocks for which assessment and
advice are provided by ICES, STECF, GFCM, ICCAT and the Black Sea Commission could be undertaken. WKD3R demonstrated that this is feasible for the four marine regions of MSFD. Further collaboration would be welcomed: o ICES could repeat the process started by WKD3R, if requested

Way forward, Guideline completion and other recommendations Item 6 Criterion 3.3 (Population age and size distribution) Within the current reform of the CFP, management is with respect to Criteria 3.1 and 3.2 and as such, Criterion 3.3 may not be
essential in the short-term. Criterion 3.3 relies on the concept of a healthy size/age structure of the stocks, and it is not essential to assess the exploitation status of resources in terms of pressure (F) and status (SSB). Ability to track biological improvements in stock development (with a time delay) as MSY-based management is achieved. Only two available indicators (3.3.1 and 3.3.3) should be monitored for trends while their utility is further investigated.
