How to fish it · for Atlantic Salmon
When
Mainly August through October per Nevern AA. Grilse arrive from July. Fish on the drop after rain.
Where
Lower pools above the tidal limit at Newport. Nevern AA named beats.
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
Water at 21.4°C. This is the line where catch-and-release kills atlantic salmon. Do not fish for them today.
