Why fish Coalfish at The Breaches, Kilcoole

Kilcoole shingle-belt outflow under the rail bridge. Under-targeted specimen mullet; flounder, sea trout and bass at the same channel.

Marsh gullies and mountain streams from the Kilcoole shingle belt meet the sea under a railway bridge, on older maps marked as 'The Breaches'.

This is ERFB Site 23, not the Broad Lough / Vartry system at Wicklow (Site 28 Broadlough on the Murrough), which lies about 12 km south.

The single most under-targeted specialist mark on this stretch of coast, the Eastern Regional Fisheries Board guide explicitly notes mullet 'well over the specimen weight of 5 lb' present, with 'little attempt to catch them'.

Flounder concentrate at the freshwater interface; sea trout pass through on their run; bass at dawn/dusk on the outlet.

Harbour walls, pier mouths and rough ground where baitfish shoals run, especially in colder months when pollack fishing fades.

Kilcoole outflow specialist mark, specimen mullet and flounder, groundbait and finesse tactics required.

The Eastern Regional Fisheries Board guide points straight at this mark (Site 23): 'Some of these fish appear to be well over the specimen weight of 5 lbs but to date there has been little attempt to catch them.

Time spent fishing for both of these species may be well rewarded'.

Two tactical points: (1) the pool BEHIND the rail line is sheltered from open-sea conditions and fishes on days the open beach is unfishable; (2) flounder concentrate at the freshwater/saltwater interface at all tides, not just slack, this is reliable winter fishing.

Season and tide

At The Breaches, Kilcoole, Coalfish is worth targeting in Seasonal on this mark. Coast-wide, Coalfish runs September to May (peaks October to March autumn and winter from piers).

Wider mark season: Grey mullet: May to October (specimen-class possible), Flounder: year round at freshwater interface, Sea trout: July to October, Bass: April to November (peak autumn Sep to Nov; outlet at dawn/dusk), Dab: October to February

Tide guidance here: Mullet move into the pool behind the bridge on the flood and back out on the ebb, both windows fish the channel. Bass at the outlet on the flooding tide at dawn or dusk. Flounder concentrate at the freshwater/saltwater interface throughout the tide.

Moving water around piers and harbour mouths. Night tides in autumn and winter often produce the biggest fish. Coalfish are less structure-dependent than pollack and will chase prey across open ground.

Fishable phases: first-flood, mid-flood, high, first-ebb, mid-ebb. Peak: mid-flood, first-ebb.

Tactics on this mark

Fish small metals, feathers or natural baits in the flow around harbour mouths and deep pier edges, letting lures swing through the current in autumn and winter.

Float-fished bread or flake (mullet, specialist technique); Light ledger with worm or crab close in (flounder); Surface lures or sub-surface plugs at the outlet (bass); Single-handed fly (sea trout)

Gear: vertical drop. Facing E.

• Same methods as pollack, spinning, jigging, feathers
• More aggressive takes than pollack, heavier gear can be used
• Float-fished bread or flake (mullet, specialist technique)
• Light ledger with worm or crab close in (flounder)
• Surface lures or sub-surface plugs at the outlet (bass)
• Single-handed fly (sea trout)

Baits and lures

Coalfish baits and lures: Feathers; Sandeel; Mackerel strip; Soft plastics; Metal jigs.

What this mark typically holds: Bread/flake (mullet); Ragworm; Peeler crab; Small lures (bass/sea trout).

Bread/flake (mullet); Ragworm; Peeler crab; Small lures (bass/sea trout)

Access and ground

Long walk in from either Kilcoole (north) or Newcastle (south). The railway bridge with the freshwater channel is the singular landmark. No road access mid-beach. The pool behind the rail line is sheltered from open-sea conditions and fishes when the open beach does not.

Parking: Limited; Kilcoole station or Newcastle area as starting points.

Safety: SAC/SPA wetland, quiet behaviour required, bird sensitivities apply. Fast-flowing channel at peak ebb, never wade across. Long walk in, no facilities, patchy mobile coverage.

Nearest tackle: Wicklow town or Greystones tackle shops; specialist mullet bread/groundbait is BYO.

Nearest town: Newcastle. Skill level: Intermediate.

Size and identification

Typical shore size around 300 g to 1.5 kg on harbour and rock marks; specimen class from about Larger coalfish over 2 kg possible in deep water channels.

Very similar to pollack but distinguished by a straight lateral line (not curved), a white lateral line, and a jaw that is roughly equal (not strongly protruding). Dark green-black back, pale flanks. Young coalfish (known as 'billets' or 'cuddies') are common from pier walls.

Tip: Coalfish and pollack are often caught together from the same marks. The autumn run of coalfish through Greystones Harbour can produce excellent sport, small shoals of 500 g to 1 kg fish attack feather rigs in the harbour mouth from September onwards.

Irish shore context: record class around 7.26 kg.
