EUROPEAN SILVER EEL MIGRATION AND FISHERIES‐INDUCED MORTALITY IN THE HAVEL RIVER SYSTEM (GERMANY)
ABSTRACT By using acoustic telemetry, the behaviour and fishery mortality of silver eels Anguilla anguilla (L.) were studied during the early phase of the spawning migration through the Havel River downstream to the river Elbe. A total of 99 female silver eels were implanted with acoustic transmitte...
