Stoneflies
Caddisflies
A short Old Red Sandstone spate river on the Iveragh peninsula, draining off the south-western flank of the Reeks past Cahersiveen into Valentia Harbour. Unusually for an Irish salmon river in 2026, the Ferta is OPEN for a limited harvest — Inland Fisheries Ireland's Standing Scientific Committee assessed a small exploitable surplus, and the river carries a quota of 65 salmon tags for the season. It is a standard Schedule 2 'blue tag' river, NOT a brown-tag river — in Kerry the brown-tag water is the Roughty, not the Ferta. It remains a small, rain-dependent system: a grilse-and-sea-trout spate river that fishes best in the 12–36 hours after a flood as the water drops and clears, with little to offer in low summer water. The spring run is minor; grilse build from June, and sea trout are a genuine second target through the summer. The bedrock is Devonian Old Red Sandstone (the Valentia Slate Formation), giving acidic, fast-draining water. The harvest window runs early April to the end of August under tag; catch-and-release applies from 1 September to the close. Access is largely private and landowner- or guide-controlled — confirm before travelling.
EPA freshwater monitoring on the River Ferta confirms mayflies, stoneflies, caddis, aquatic diptera and freshwater shrimp are present. This is food-presence evidence from kick sampling, not a record of emergence timing or a dependable rise.
