Whiting
Whiting are a cod-family fish found all around the Irish coast, and for shore anglers they're the backbone of winter night fishing. Small by comparison to their relatives — most fish run under a pound — they make up for it in numbers and consistency.
When other species have moved offshore, whiting fill the gap from October through April, giving beach anglers reliable action on dark, cold nights.
Scientific Name: Merlangius merlangus
- Blue-green back fading to silver-white flanks and belly; a dark brown lateral line that curves upward toward the large eyes distinguishes it from haddock, which has a black lateral line.
- Three dorsal fins set close together, two anal fins — the classic cod-family layout. A small dark spot sits at the base of each pectoral fin, a reliable ID mark.
- Chin barbel is tiny or absent, unlike the more prominent barbel on cod or haddock. Upper jaw slightly overhangs the lower.
- Shore fish typically run 25–40 cm and weigh under a pound. A fish over 45 cm is a genuine specimen; the Irish record stands at 4 lb 14.5 oz.
What to know
Habitat Distribution
- Native to Irish waters and found all around the coast. Abundant in the Celtic Sea and along the south and west coasts; present in the Irish Sea along the east coast.
- A benthopelagic species — lives and feeds near the seabed but moves up in the water column at night. Rarely found below 100 m; most fish stay in the 30–100 m range offshore.
- Tolerates sand, mud, gravel and mixed ground. Inshore fish in winter favour sandy beaches and shallow bays, often in just 2–8 metres of water.
- Moves inshore as sea temperatures drop in autumn, making them accessible to shore anglers through winter; retreats to deeper water in summer.
Key Locations
- Kilcoole Beach and The Murrough, Co. Wicklow — the most-referenced shore marks on the east coast for winter night sessions, with shoals in easy casting range from October onward.
- Greystones South and Brittas Bay, Co. Wicklow — part of the Wicklow shingle belt that holds whiting reliably through the October–April window.
- Youghal Beach, Co. Cork — noted for consistent shore whiting throughout winter, with fish accessible from the beach.
- Offshore sandbanks off Cork — East Ferry, Cobh, Crosshaven, Kinsale and Dungarvan all have charter boats or launch facilities to reach these marks, which produce the largest specimen-class fish.
- Kenmare Bay, Co. Kerry — site of the Irish record catch, and a productive area for larger whiting from boats.
Specific Spots
- Sandy beaches and shingle banks in 2–8 metres — the depth range a moderate cast reaches on a falling tide. Whiting follow baitfish and sandeels pushed inshore by tide and darkness.
- Harbour mouths and estuary edges concentrate fish at night, particularly where tidal flow creates a current break over a sandy or muddy bottom.
- Offshore sandbanks in 20–50 metres hold the larger specimens; the banks off the Cork coast are the main source of specimen-class fish.
- On beaches, the gutter between a sandbar and the shore is a prime feeding lane — whiting herd small fish into shallow water and feed confidently after dark.
Whiting FAQ
Answers from onWater's species guide.
What are the best lures and bait for Whiting?
Ragworm and lugworm are the go-to shore baits, fresh worm on a size 1 or 2 Aberdeen hook, presented on a two-hook flapper cast into the gutter. Cocktail baits (worm tipped with a sliver of fish) can improve takes. Fish strip and whole small sandeel are the top boat baits, fished on a paternoster close to the bottom.
When is the best time to fish for Whiting?
October to April, the full shore fishing window, with whiting accessible from beaches and shingle banks as sea temperatures drop and shoals move inshore. November to March, peak shore sport, with the largest and most consistent shoals close in.
How do you catch Whiting?
Shore anglers target whiting on dark winter nights, casting a two-hook flapper baited with worm or fish strip into the gutter behind a sandbar on a falling tide. Boat anglers work offshore sandbanks with a paternoster rig and fresh fish bait, drifting or anchoring over sandy or muddy ground in 20–50 metres.
What do Whiting eat?
Whiting feed heavily on sandeels, small sprats and other baitfish, which is why fish strips and whole small sandeels are consistently the top boat baits, they match what whiting are already chasing.
Where do Whiting live?
Native to Irish waters and found all around the coast. Abundant in the Celtic Sea and along the south and west coasts; present in the Irish Sea along the east coast. A benthopelagic species, lives and feeds near the seabed but moves up in the water column at night.
