Temporal changes in European eel, Anguilla anguilla, stocks in a small catchment after installation of fish passes
Abstract Changes in the abundance of European eel, Anguilla anguilla L., in the River Frémur, France, were examined over an 8‐year period. Natural connectivity of the river was disturbed by three high dams that inhibited eel upstream migration and reduced recruitment by elvers and yellow eels. After...
