Interactions between the marine environment, predators, and prey: implications for sustainable sand eel fisheries

Contract nr: QLK5-CT-2000-30864
Project type: RS (Research and Technological Development Project)
Starting date: 01-12-2000
Duration: 48 months
Total cost: 4,101,015 EUR
EC Contribution: 2,578,000 EUR
Scientific Officer: Dominique LEVIEIL
Research topic: 5.1.2. Sustainable fisheries and aquaculture

Abstract:
The industrial sand eel fishery is the largest single fishery in the North Sea. Sand eels are major prey for toppredators such as seabirds. Severe ecosystem effects of sand eel stock collapses have occurred, but the fishing industry contests the view that its activities negatively affect toppredators. Earlier studies on ecosystem effects have focused on the geographical overlap between feeding areas of seabirds and sand eels, but the relationship between prey density and availability to predators is still poorly understood. In this project, predator-prey relations in marine ecosystems are studied in unprecedented detail using advanced technology. Threshold values of prey density will be established, under which feeding is not feasible. The knowledge obtained within this project should provide fishery managers with high, quality advice with respect to exploitation strategies that mitigate the impact on toppredators of the marine foodweb.
