Fish being moved to oxygenated flowing water further downstream as water levels drop across country
Along the Odet River in Brittany, fisher Mathieu Le Bouter and a dozen volunteers are catching hundreds of trout and young salmon – not for sport but to save them.
They are only a few miles from the source of the river, which springs from the Black Mountains in Finistère and runs for about 40 miles (65km) into the Atlantic Ocean, but the water is barely up to their knees.
