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.
