Fish a sensible line-and-fly combination for the height and pace of water.
Kit
13 ft #8/9 double-hander in spate, 10 ft #8 single in low water. Floating line plus a fast-sink tip. 12–15 lb fluoro tippet.
Why this works
Water at 21.1°C. This is the line where catch-and-release kills atlantic salmon. Do not fish for them today.

Piloña is one of the 2026 salmon-eligible stretches ("pilona_to_coto_infiesto_inclusive", up to Coto Infiesto), sharing the combined Sella-Piloña annual quota — this river's own is_salmon_river flag and species list previously didn't reflect that despite salmon_fly_pack_ref already pointing at the shared Asturias salmon fly pack. Above Coto Infiesto likely falls under the mountain-zone trout rules instead; the exact split point isn't verified here. Sella-Piloña basin quota for 2026: 52 salmon total (max 21 in zona libre).
Sea trout: Variable seasonal (2026)
