Route selection, migration speed, and mortality of silver eel passing through two small hydroelectric facilities
Abstract The European eel is a highly threatened species according the European Inland Fisheries Advisory Commission (EIFAC) and the Food and Agriculture Organization of the United Nations (FAO).
