ICES AssessmentThe Precautionary Framework
![Page 12: European Fisheries Management Rainer Froese IFM-GEOMAR.](https://reader036.fdocuments.us/reader036/viewer/2022062304/56649d415503460f94a1bcdd/html5/thumbnails/12.jpg)
The Common Fisheries Policy
• “A common policy in the sphere of agriculture and fisheries”, 1958
• First common measures in 1970 on equal access to fishing grounds outside a ‘coastal band’; subsidies for modernization of fishing vessels etc.
• 200 nm EEZ in 1976
• Common Fisheries Policy since 1983
![Page 13: European Fisheries Management Rainer Froese IFM-GEOMAR.](https://reader036.fdocuments.us/reader036/viewer/2022062304/56649d415503460f94a1bcdd/html5/thumbnails/13.jpg)
The Common Fisheries Policy
• Ensure exploitation of living aquatic resources that provides sustainable economic, environmental and social conditions.
• Precautionary approach to: – protect and conserve living aquatic resources; – provide for their sustainable exploitation; – minimise the impact of fishing activities on marine ecosystems; – efficient fishing activities within an economically viable and
competitive fisheries and aquaculture industry;– provide a fair standard of living for those who depend on fishing; – take into account the interests of consumers.

The Management Process1. DG Fish asks ICES for scientific information
and advice.2. ICES working groups assess stocks and
recommend total allowable catch (TAC) including discards and ‘unaccounted’ catch, based on a framework aiming to prevent the collapse of stocks.
3. Several official committees (ACFA, STECF, RACs) apply pressure for higher TACs.
4. DG Fish recommends higher TACs (10-30% beyond ICES recommendation, ignoring discards and IUU catches).
5. Council of Agriculture Ministers sets TACS 10-30% beyond DG Fish recommendation.
