Turbot

Turbot are native to Irish coastal waters and rank among the most coveted flatfish a sea angler can land here. They grow large — the Irish record stands at 34lb — and double-figure fish, while rare today, still turn up along the west and north coasts.
Most shore and boat anglers encounter them as a bonus over clean sand or shingle, but dedicated turbot hunters target specific marks from Donegal to Cork.
Scientific Name: Scophthalmus maximus
Also known as An turbard
- Almost circular body — large specimens earn the nickname 'dustbin lid'; broad, rounded profile unlike the more oval plaice or flounder.
- Upper (left) side is mottled dark brown with lighter circles and darker spots; underside white. Skin covered in small bony bumps rather than scales.
- Mouth is large and curved — a big turbot can swallow a whole mackerel whole. Eyes are relatively small for the size of the head.
- Typical shore fish run 1–6lb; specimen qualifying weight is just over 11lb. Fish to 80cm are possible; the Irish record is 34lb.
What to know
Habitat Distribution
- Native to Irish waters; found around the entire coastline but more common along the west and north coasts than the east.
- Adults favour clean sand, gravel, or shell-gravel seabeds from roughly 20m down to 80m; juveniles move into the surf zone and shallow inshore areas.
- Juveniles reportedly prefer brackish conditions, so western estuaries are worth targeting in early spring.
- Key areas include the Donegal coastline (Mulroy Bay, Tory Island sandbanks), the Causeway and Antrim coasts, Belmullet, and Cork Harbour.
Key Locations
- Mulroy Bay, Donegal — regularly produces turbot, mostly in the 3–6lb range from the large sandy bay system.
- Tory Island sandbanks, Donegal — specimen fish have been recorded over the offshore sandbanks here.
- Belmullet, Co. Mayo — the west coast around Belmullet still holds good turbot along its sandy and mixed ground shores.
- Causeway and Antrim coasts (Red Bay, Glenarm) — historically productive for large fish; commercial pressure has reduced numbers but fish are still present.
- Cork Harbour — a fair venue for the species in the south, though double-figure fish are now uncommon.
Specific Spots
- Sandy or shingle beaches with strong surf — turbot hold at the edge of the broken water where baitfish and sandeels get pushed around by wave action.
- Sandbanks and clean sandy bays: the fish lie flat and wait for prey to pass over the crest or down the face of a bank.
- Estuaries and tidal outflows — juvenile turbot use brackish water, and adults follow baitfish into tidal runs on the flood.
- Surf beaches with a stream or freshwater outflow nearby concentrate fish; the outflow at Gallagher's Stream on the west coast is one documented example.
Turbot FAQ
Answers from onWater's species guide.
What are the best lures and bait for Turbot?
Fresh mackerel strip or whole small mackerel is a reliable boat bait, cut the strip long and thin to mimic a sandeel profile rather than a wide chunk. Ragworm and lugworm account for shore-caught turbot, especially smaller fish on surf beaches; fish them on a long-shank hook close to the bottom.
When is the best time to fish for Turbot?
Spring (March–May), juveniles move into estuaries and shallow surf zones early in the season; worth targeting western estuaries from early spring. Summer (June–August), peak season for boat fishing over offshore sandbanks; fish are more widely distributed and feeding actively.
How do you catch Turbot?
Most Irish turbot are caught from boats drifting or anchored over clean sandy ground, fishing bait hard on the bottom. Shore anglers target surf beaches and tidal outflows, particularly on the west and north coasts, casting into broken water after strong seas have settled.
What do Turbot eat?
Sandeels are the primary forage, turbot lie on the bottom and ambush them as they pass overhead. Long, slim sandeel-imitation lures and baits are the go-to choice. Small fish including mackerel, sprat, and juvenile flatfish are taken by larger adults. Fresh mackerel strip or whole small mackerel are proven boat baits.
Where do Turbot live?
Native to Irish waters; found around the entire coastline but more common along the west and north coasts than the east. Adults favour clean sand, gravel, or shell-gravel seabeds from roughly 20m down to 80m; juveniles move into the surf zone and shallow inshore areas.
