How to fish it · for atlantic salmon
When
Occasional fish through summer and autumn. The Artro is not a salmon destination.
Where
Lower Artro pools above the tidal limit at Llanbedr.
Method
Small doubles 10 to 12 across-and-down on a floating line; small tubes on a sink-tip in spring or coloured water. Fish the named lies in each pool, working systematically before moving on. Mandatory catch-and-release under NRW byelaw — every salmon goes back.
Kit
10 ft #7/8 single-hander or 11 ft switch — small spate scale; double-handers are wasted on these rivers. Floating line plus light sink-tip. 10 to 12 lb fluoro tippet.
Why this works
Good conditions. Clarity is favourable (95), Feeding time is weakest (10).

About this water

Short Ardudwy spate from the high country around Cwm Bychan to Cardigan Bay at Llanbedr — small, slate-walled, and very much a local club fishery. Sewin and brown trout lead the calendar with the occasional salmon. NRW catch data is sparse to vanishing; treat the Artro as honest small-water sport, not a destination.

Sea trout: Variable seasonal (2026) — Small Ardudwy spate with very low recorded catches. All-Wales At Risk picture applies. Honest local sport on the right water rather than a destination fishery.
