| Summary: | At the time of their downstream migration, the eel mortality is significant related to their passages in the turbines of the hydroelectric power stations. Physical or behavioral barriers exist, but there are expensive or with a random effectiveness. The transfer of fish towards the downstream or the suspension of the factories are more and more mentioned. / Lors de leur dévalaison, les anguilles subissent des mortalités importantes liées aux passages dans les turbines des centrales hydroélectriques. Pour y remédier des barrières physiques ou comportementales existent, mais sont d'une mise en oeuvre coûteuse ou d'une efficacité aléatoire. Le transfert des poissons vers l'aval ou l'arrêt momentané des usines sont des possibilités de plus en plus fréquemment évoquées. |
