From our UK edition
Save our salmon Sir: On a Winston Churchill scholarship to discover what other North Atlantic host countries were doing for beleaguered salmon numbers in the 1990s, I found that the Canadian government considered hydroelectric schemes far less green than wind farms (‘Something’s fishy’, 1 September). The Canadian experience was that hydro units minced fish, interfered with the movement of migratory species, and often produced electricity in amounts well below original specification targets. On return to the UK, I looked closely at ‘my’ Scottish river, Carron Kyle of Sutherland. Water is abstracted from headwaters to feed turbines in a neighbouring catchment.
