European Plaice
Plaice are Ireland's most recognisable inshore flatfish, found all around the coast wherever clean sand and shingle meet the sea.
Commercial pressure has thinned the population considerably, but shore and boat anglers still connect with them each spring and summer.
Cork Harbour is the current standout for bigger fish, while the north coast around Portrush and the east coast beaches of Wicklow produce consistent sport on light tackle.
Scientific Name: Pleuronectes platessa
Also known as Leathóg bhallach
- Brown topside covered in bold, irregular orange spots that never disappear even when the fish adjusts its base colour to match the seabed — the clearest ID feature.
- Pearly white underside; smooth skin with small scales and a distinctive bony ridge of bumps running behind the eyes on the top side.
- Both eyes sit on the right side of the body; oval outline with a small, pointed mouth.
- Typical rod-caught fish run 1–3 lb; the Irish record stands at 8.23 lb, and the specimen weight is set at 2.65 lb (48 cm).
What to know
Habitat Distribution
- Native to Irish waters; found all around the coastline wherever suitable sandy or shingle ground exists, from the shoreline out to around 50 m depth.
- Favours open sandy beaches, shell-and-gravel mixed ground, and offshore sandbars — rarely over hard or rocky reef.
- Key areas include Cork Harbour (south coast), the Portrush–Portstewart stretch and Balintoy (north coast), Lough Swilly and Mulroy Bay (Donegal), and the Wicklow beaches on the east coast.
- Can tolerate some brackish influence at estuary mouths but is primarily a marine species.
Key Locations
- Cork Harbour — currently the most consistent mark for larger plaice on the south coast.
- Portrush and Portstewart, Co. Antrim — the causeway bank and rock marks between these towns have a long history of plaice and turbot fishing.
- Lough Swilly and Mulroy Bay, Co. Donegal — quiet bays in this area produce plaice sporadically through summer.
- Wicklow coast (Brittas Bay, Kilcoole, Silver Strand, the Murrough) — reliable east coast spring and summer shore marks over clean sand and shingle.
- Balintoy Harbour, Co. Antrim — has produced specimen fish on the north coast.
Specific Spots
- Sandy surf tables and inner beach shelves — plaice feed close in, often within 30 metres of the shore on calm days, working the tide over clean ground.
- Flooding tide edges where sand meets shell or light gravel; the change in bottom texture concentrates worms and small crustaceans that plaice root out.
- Quiet bays and harbour mouths where tidal flow slows and fine sand settles — fish hold here to feed rather than fight strong current.
- Offshore sandbars accessible by boat; fish lie on the downtide face of the bar where food washes over the crest.
European Plaice FAQ
Answers from onWater's species guide.
What are the best lures and bait for European Plaice?
Ragworm and lugworm are the standard baits across all Irish plaice marks, fresh worm consistently outperforms frozen; a single worm threaded neatly on a fine-wire hook is the classic presentation.
When is the best time to fish for European Plaice?
Spring (April–May), fish move inshore after spawning; early-season fish can be lean but sport picks up quickly as water warms. Early summer (May–July), peak shore fishing on most Irish coasts; fish are in full condition and feeding actively on sandy beaches.
How do you catch European Plaice?
Shore fishing accounts for most recreational plaice catches in Ireland, with anglers casting a running ledger rig onto clean sandy ground from beaches and harbour walls. Boat anglers work offshore sandbars, particularly off the south and west coasts.
What do European Plaice eat?
Ragworm and lugworm are the primary natural food source and the go-to shore baits in Ireland, a fresh worm presented on a size 1–2 Aberdeen hook on a long flowing trace is the standard approach.
Where do European Plaice live?
Native to Irish waters; found all around the coastline wherever suitable sandy or shingle ground exists, from the shoreline out to around 50 m depth. Favours open sandy beaches, shell-and-gravel mixed ground, and offshore sandbars, rarely over hard or rocky reef.
