The mild climate of Camargue and the abundance of fish such as mussels, wolves, shads make the delta a great fishing spot. Catfish have developed abundantly in the Rhone, there are certainly the largest specimens in Europe. The catfish are therefore freshwater fish that average 1.5 m long but can reach 2.73 m. In the Petit-Rhône, a few kilometers from the Sylvéréal bridge, some fish exceed 2 m 60 and weigh more than 100 kg.
