BBC NEWS | Europe | Cleaner Seine hosts salmon again: "Wild salmon are returning to the French capital for the first time in almost a century, scientists say.

Historically, Salmo salar - or Atlantic salmon - used to migrate up the Seine river for part of the year to spawn.

But increased pollution of the water and the building of dams after World War I saw their number dwindle.

By 1995, the salmon were gone, and only four species of fish braved the Seine's dirty waters, which washed up hundreds of tonnes of dead fish a year."
