How to fish it · for Atlantic Salmon
When
Spring run from March; grilse from June; main run summer through September. The Boyne is recovering from historic depletion — fish carefully, release everything.
Where
Beats from Trim through Slane to the tidal limit. Heads and tails of named pools; many stretches fish through Boyne Anglers club water.
Method
Spring: tube on a sink-tip swung deep through the main pools. Summer and autumn: small doubles on a floater across-and-down. Catch-and-release on most beats.
Kit
12 to 13 ft #8 double-hander on the bigger water; 11 ft switch on smaller beats. Floating line plus fast-sink tip. 10 to 12 lb fluoro tippet.
