1. What can we learn from D3 assessments?

2. European Framework
EEA has responsibility to develop a European assessment in 2019;
At the European level we need European indicators & aggregation rules to support our assessments;
Indicators are needed for all descriptors, and to support our analytical framework (DPSIR);
Indicators need to have a common approach;
Indicators should be based on information provided in 2018.

3. Good Environmental Status
D3 Commercially exploited fish & shellfish
Target: GES
Good Environmental Status

4. D3 Pressure criteria 3.1 – fishing mortality State criteria
No pressure
Intense pressure
Level of impact acceptable D3
Pressure criteria
3.1 – fishing mortality
State criteria
3.2 – biomass
3.3 – population structure
GES boundary
Level of impact not acceptable
State-based descriptors
D1, 3, 4, 6

5. Reference points 3.1 Fishing mortality – EU agreement Fmsy
3.2 Biomass – EU agreement for SSB
3.3 Population structure – no accepted approach
Embedded in CFP management plans or ICES MSY advice framework

6. Challenges Not all stocks assessed
Pressure influences state, but does not determine state
Mixed fisheries: where managing pressure on target stocks may not impact the state of non-target stocks

7. Catch advice- examples

8. Catch advice - examples

9. From stock to regional assessments
Method – same in each MSFD regions:
Step 1 – List commercially exploited fish & shellfish stocks
Step 2 – Catalogue & document available information for assessment
Step 3 – Evaluation of GES by appropriate groupings (e.g. demersal, pelagic, shellfish).
Step 4 – Overall status, issues, problems, gaps and links to other MSFD

10. Example: subregions Celtics and Great North Seas

11. Aggregating the information, including gaps
stocks with F & SSB info
stocks with SSB info
stocks with F info
stocks with no GES info
Source EEA assessment using
ICES, STECF & ICCAT data

12. Assessing GES for D3
Source EEA state of Europe’s seas report using ICES,
STECF & ICCAT data

13. Findings Aggregation as much a policy decision as a science decision
Aggregation rules can be pressure oriented or state oriented
Is OOAO appropriate for pressure and for state criteria?
Much information already available for broad assessments
Aggregation methods must also illustrate what we don’t know
Aggregation rules need to show progress
