Salmon return to UK rivers after conservation projects

Many rivers in the UK that were once famed for their salmon saw them disappear but now they are coming back as conservation projects prove to be a success.

At this time of year the fish are swimming upriver to breed and, if you are lucky, you may see them leaping out of the water to overcome obstacles.

John Maguire reports from the banks of the River Dove in Derbyshire - one area where salmon are making a comeback.
