Session A7: Migrational Behavior of PIT-Tagged Fish at Geesthacht Weir, River Elbe, Germany
Abstract: Nearby the town of Geesthacht, 35 km upstream of Hamburg, exist the only one migration barrier for fish on the German side of the Elbe. This weir was built in 1960 to regulate the tidal influence and to obtain a constant water level upstream. Since 1998 fish passage is provided by a natura...
