Symposium on the results of the Eels & Installations R&D programme 28-29 November 2011, Paris. This synthesis is available on Tecnical portal of OFB (Office français de la Biodiversité) (https://professionnels.ofb.fr) International audience The European eel was until recently an abundant species in most European freshwaters, but its numbers have fallen sharply since the 1970s and 1980s. The causes of the rapid decline, which now threatens the very existence of the species, are clear for the most part and include fishing, poor quality of water and habitats, fragmentation of rivers by weirs and dams, and death in hydroelectric turbines. To meet the restocking goals set by the European Union (EU), France has initiated a management plan addressing each of the factors responsible for the decline of the species. Concerning river obstacles and turbines, the Ecology ministry launched an R&D programme bringing together a number of partners, including Ademe, Onema and five hydroelectric companies, namely Compagnie nationale du Rhône, EDF, France Hydro Electricité, GDF Suez and Société hydroélectrique du Midi. The programme, managed by a steering committee comprising the partners mentioned above and placed under the responsibility of the Ecology ministry, targeted a number of operational goals that resulted in the development and testing of technical solutions designed for rapid implementation in the field. All programme results were presented on 28 and 29 November 2011 at the feedback symposium which brought together 160 persons, including researchers, water managers, associations and hydroelectric companies.
