Directions
Seasons & zones
- Trout 2nd Saturday of March → 3rd Sunday of September
- Grayling 3rd Saturday of May → 3rd Sunday of September
France national rule: grayling opens 3rd Saturday of May in all waters. In 1st category (salmonid) rivers, grayling closes with the trout season on the 3rd Sunday of September. Departmental regulations may impose additional restrictions. Always check the relevant département's 2026 arrêté préfectoral.
- Coarse 2nd Saturday of March → 3rd Sunday of September
Chub has no national closed season of its own in France — on a 1st-category (salmonid) reach like this, ALL fishing (any species, any method) is prohibited outside the water's own open season (Code de l'environnement Art. R436-6), so chub simply inherits the trout/grayling season rather than following a separate coarse-fish law.
