Seasons & zones

Trout Third Sunday of May → 15 August
The Casaño is a headwater tributary of the Cares, draining the Picos de Europa above the Cares' salmon-zone reserve limit, so it sits in the mountain-zone tributary network. Mountain-zone trout (zona de alta montaña): opens Third Sunday of May, not the general 15 March, minimum size 17cm (vs. 19cm general). Asturian regulation classifies any tributary joining above a salmon river's designated zone-limit point as alta montaña water. Inferred here from confluence position, not a verified lookup against the official cotos map (pescafluvial.asturias.es) — confirm before treating as final.
