Disease, not contamination, killed Carcassonne's Lake Cavayère carp

Carp in Lake Cavayère near Carcassonne died from a disease, not contamination, according to recent findings. There is no risk to human activity. Tests revealed the carp deaths were likely caused by "sleeping sickness" or carp viremia, diseases common in warmer water. The city of Carcassonne confirmed no epidemiological risk after water samples were taken. The lake's water level is low, but nautical activities continue despite a municipal ban on swimming. The fishing federation is working with authorities to monitor the situation.
