Despite decades of ecological damage, the great River Danube is still home to all sorts of Europe's most exciting species - birds, mammals, and fish. But some of them often seem to be swimming against the tide - or the current - as they try to survive. Nick Thorpe joins the anglers and biologists working to reintroduce a regal fish, Hucho Hucho, also know as the 'Danube salmon', once a common sight to the waters of the Sava River. It is a magnificent creature, beloved by anglers and admired by environmentalists, who all want to see its numbers along the watercourse increase. But can this species - which one campaigner compares to the endangered wild tiger - still find places to spawn in peace?
