Amateur fishing is not authorized in the ponds and lagoons of Camargue, and only professional fishing is practiced there in certain places. The choice of the species fished and of the techniques is linked to the different environments (sea, Rhône, ponds, sandy coast) and fluctuates according to the degrees of salinity. A few dozen fishermen practice fishing in the ponds with trap nets called trabaques. They mainly catch eels and atherins, small fish intended for frying.
