FREE THE RHINE FOR THE SALMON
The goal of the “Salmon Comeback!” campaign is the return of the Atlantic salmon to the whole of the upper Rhine river basin.
Originally the Rhine was the longest European river habitat of the Atlantic salmon (Salmo salar). Even as recently as a hundred years ago, a million salmon a year found their way up the Rhine and its tributaries, well into all the Swiss Alps. Nowadays there are only a few hundred individuals left in the Rhine from Rotterdam to the Upper Rhine. Migration stops at this point due to several dams.
Salmon Comeback! is a coalition put together to ensure that all parties involved fulfil their commitments to create the necessary conditions for salmon to return back to their best spawning grounds near Basel. A joint agreement was worked-out and signed at the ministerial conferences in Bonn (2007), Basel (2013), Amsterdam (2020).
