"Mainly led by young scientists and supported by the Rhône-Méditerranée-Corse Water Agency, this project assesses the health of fish in the Saône, from the source to the confluence with the Rhône, through various research areas: noise pollution, artificialization, rising temperatures, etc. In the same proportions as the air, the water is experiencing warming. The temperature of the Saône is increasing by an average of 0.7°C per decade, which is enormous and compromises the viability of the environment. Fish have evolved so that their metabolism functions optimally at relatively low temperatures.
