Point sampling the abundance of European eel ( Anguilla anguilla ) in freshwater areas
International audience The European eel population is in decline. Urgent management actions are required. To monitor their effect, we developed a fast sampling method, applicable in shallow rivers and tributaries. We compared the Carle & Strub estimator from 35 double pass electric fishing sampl...
