ICES' Advisory Services for Sustainable Fisheries Management
The International Council for Exploration of the Sea (ICES) plays a crucial role in providing advisory services based on scientific data to promote the sustainable use of marine resources and protect the marine environment. Through the concept of Maximum Sustainable Yield (MSY), ICES aims to balance the exploitation of fish stocks while considering ecosystem effects. Stock categories are defined based on assessment methods, guiding fisheries management towards sustainability. ICES collaborates with member states to address challenges in fisheries management in the Northeast Atlantic.

Presentation Transcript
Fishing as the exploitation of a natural resorce By Eskild Kirkegaard, ICES ACOM Chair ARVI International Conference on the Future of Fisheries Vigo, 27 November 2014
Outline A few words about ICES and the basis for ICES advice on fisheries Summarize biological status of main stocks and their exploitation in the NE Atlantic, Challenges for ICES
International Coiuncil for Exploration of the Sea (ICES) Marine Science Cooperation since 1902; 20 Member Countries; Intergovernmental Organisation 360 Institutes; A network of 4,000 scientists; 1,600 scientists participating in activities annually; 150 Expert Groups that address the many diverse issues of marine ecosystems and ocean sustainability.
Based on the best data and science available from member countries, ICES runs Advisory Services: To advise on the sustainable use of living marine resources and protection of the marine environment ICES advice
ICES Member States ICES advice
MSY maximum sustainable yield Until 2009, ICES advice was based on the precautionary approach, extended by long-term considerations for maximising yield and considering ecosystem effects of the fishery. In 2010, ICES started a formal implementation of the maximum sustainable yield-concept in its advice.
Stock Categories 1 Stocks with an accepted analytical assessment and forecast for MSY MSY approach 2 Stocks with an analytical assessment and forecast accepted for trends only Developing MSY approach 2014 3 Stocks with survey-based assessments indicating trends Developing MSY approach 2014 - ? 4 Stocks with reliable time-series of catch data to approximate MSY Developing MSY approach 2014 - ? 5 Only catch or landings available Risk based approach 6 Only landings available and largely discarded Risk based approach Each category has several available methods dependent on stock status.
Stock Categories ICES provides advice for app. 260 stocks. 1/3 of the stocks are in category 1 and 2 2/3 of the stock are in category 3 to 6
ICES harvest control rule ICES bases its MSY approach on attaining a fishing mortality rate at or below FMSY. In this approach, both fishing mortality and biomass reference points are used; these reference points are FMSYand BMSY-trigger. BMSY-trigger is a biomass reference point that triggers a cautious response. ICES approach does not include a MSY biomass target (BMSY).
