Multi-objective assessment of conservation measures for the European eel ( Anguilla anguilla ): an application to the Camargue lagoons
International audience The European eel ( Anguilla anguilla ) stock has declined since the early 1970s and is currently considered to be outside safe biological limits. The European Commission has proposed a regulation (COM 2005/472 final) to establish measures for the recovery of the stock, with th...
