Atlantic salmon numbers are falling in British rivers

iNEWS reports according to the Atlantic Salmon Trust’s Missing Salmon Project, less than five per cent of salmon that leave Britain’s rivers return. Time was when salmon swam through the Thames in London, en route to their Berkshire breeding grounds. Indeed, the river was once described as a “fishful river”, and a 14th-century law was passed for the saving of its salmon.

Today, although many kinds of fish have multiplied in the Thames in the past few decades, you’d be lucky to find the majestic salmon there. But it’s not just the Thames that is lacking salmon. Wild Atlantic salmon have significantly declined in other British rivers. 

‘To save our fish, we must first find ways to unblock UK’s rivers,’ say scientists

The Guardian reports Swansea University scientists say the proliferation of weirs, dams and culverts is now creating a threat to wildlife.

Near the mouth of the River Afan in Port Talbot, south Wales, a pair of seagulls were to be seen last week pecking in a leisurely way at a dead salmon lying on a gravel bank. It was an unusual sight. Salmon are rarely found in the Afan these days. 

The scene may have been unexpected, but it nevertheless illustrates a growing problem, say researchers – one that already affects rivers across Europe and could pose even greater threats to habitats and wildlife in future.
