Look what’s struggling to swim the Thames now… trout
Michael McCarthyIncreasing numbers of rivers in towns and cities in Britain are now so clean that anglers are fly-fishing in them for trout and grayling, which are specialised clean-water species, a new book says.
Many urban watercourses, polluted by heavy industry since the 19th century, have now shed so much of their pollution that they can support populations of the aquatic insects on which trout and grayling feed, such as mayflies, and fish populations are thriving.
The phenomenon is being seen across Britain, from south London to Sheffield, and from Merthyr Tydfil to Glasgow, according to conservationist and fisherman Theo Pike, in his book Trout in Dirty Places.
