Brown trout unlikely to survive in most rivers at height of summer by 2080, says Environment Agency

It has been native to Britain for thousands of years and was heralded as the national fish on the BBC’s Springwatch, but a government report suggests the brown trout risks being wiped out in large parts of England within decades.

The first national temperature projections for English rivers by the Environment Agency forecasts that by 2080 the water will be too warm almost everywhere in England at the height of summer for the Salmo trutta species to feed and grow.
