'Climate Change' Danger to Salmon and Trout in Wales. BBC, May 17, 2010. "Climatechange could be putting salmon and trout at risk, according to work by Cardiff University scientists. Researchers studied young salmon and trout populations in the River Wye and its tributaries between 1985 and 2004. The study found salmon numbers fell by 50% and trout by 67%, with the fish hardest hit following hot, dry summers. However, the Wye and Usk Foundation said since the research, wet summers had brought improvements to young salmon and trout 'densities'. The university team said results suggested that warmer water and lower river levels combined to affect both species... The recorded fall in salmon and trout numbers was despite the river becoming cleaner. The researchers used data on fish collected each year by the Environment Agency at more than 50 locations in the Wye catchment, mostly in Wales."
