Directions
Seasons & zones
- Sea trout 1 May → 31 July
- Trout 1 May → 31 July
Sea trout: Variable seasonal (2026) — Lérez reo culture: the river has a historic reo tradition and sea trout remain the practical migratory focus now that salmon are prohibited. Stocks are present but condition-dependent — runs follow rain events. Not a reliable primary target in a poor year.
Salmon: Heritage only (2026) — Salmon fishing banned in Galicia by 2026 Xunta decree. Heritage salmon river — not a salmon fishing destination.
