Conger Eel
The conger eel is the largest eel in British waters and one of the most physically demanding fish a UK sea angler can target.
Boat anglers fishing wrecks in the English Channel and Bristol Channel account for most big fish, but rough rocky shore marks along the south and west coasts produce respectable fish too.
The UK shore record stands above 68lb; wreck fish regularly run 35–70lb, with genuine 90lb-class fish on record.
Scientific Name: Conger conger
Also known as European Conger
- Long, scaleless, muscular body — grey-blue or grey-brown on top, white belly, with a distinctive black margin along the dorsal and anal fins.
- Upper jaw protrudes beyond the lower jaw; large elliptical eyes, wide mouth, and rows of small, sharp teeth — the key ID feature separating it from the common eel.
- Dorsal, tail, and anal fins fuse into a continuous fringe running the full length of the body, ending in a pointed tail.
- Shore fish typically run 5–25lb; wreck fish regularly reach 35–70lb, with specimens over 90lb caught on UK charter boats.
What to know
Habitat Distribution
- Native to UK waters; most numerous along the south and west coasts of England, Wales, and Scotland, and all around the Irish coast — far less common on eastern coasts.
- Rocky ground, boulder fields, and wrecks are the core habitat — congers spend daylight hours wedged into holes, crevices, or wreck cavities, emerging at night to hunt.
- Inshore fish occupy depths from the low-tide zone down to around 100m; the very largest fish live on deep offshore wrecks, sometimes below 500m.
- Smaller fish come inshore at night, making rocky shore marks and harbour walls viable targets; fish over 50lb are almost exclusively a boat proposition.
Key Locations
- English Channel wrecks off Brighton and the wider Sussex coast — hundreds of wrecks within range, regularly producing fish to 70lb-plus.
- Bristol Channel — the second-highest tidal range in the world creates rich feeding grounds; sizeable conger are present throughout, particularly over rocky reef and wreck marks.
- South-west England (Cornwall, Devon) — rocky shore marks and offshore wrecks both produce fish; some of the most accessible big-conger shore fishing in the UK.
- West coast of Wales and Scotland — conger present along most of the rocky western seaboard, with fish caught from shore marks as well as charter boats.
Specific Spots
- On wrecks, concentrate your bait right at the hull — congers hold tight inside the structure and rarely move far to intercept a bait sitting in open water.
- From shore, fish tight to large boulders, rock ledges, and the base of harbour walls after dark; any dark crevice that holds small fish will hold conger.
- Slack-water periods on tidal marks are the most productive windows — in high-tidal-range areas like the Bristol Channel, strong flow makes bait presentation difficult and fish less active.
- Sandy or muddy patches immediately adjacent to rocky reef or wreck edges are worth targeting; conger patrol these transition zones when feeding.
Conger Eel FAQ
Answers from onWater's species guide.
What are the best lures and bait for Conger Eel?
Fresh mackerel is the benchmark bait, a flapper presentation for wreck fishing, a joey mackerel or large section for shore work; the fresher and smellier, the better.
When is the best time to fish for Conger Eel?
Caught year-round, but peak boat and shore fishing runs from June through November when inshore sea temperatures are at their highest and fish are most active in accessible depths.
How do you catch Conger Eel?
Most UK anglers target conger from charter boats over known wrecks, anchoring uptide and presenting a fresh fish bait hard on the bottom during the slack-water period. Shore anglers fish rough rocky ground and harbour walls after dark on a running ledger, keeping the bait tight to structure.
What do Conger Eel eat?
Fish make up the bulk of the diet, pouting, whiting, mackerel, and small cod are all taken. A fresh mackerel flapper (the backbone removed so the flesh opens out and releases scent) is the most widely used wreck bait in UK waters; mackerel heads and guts work equally well.
Where do Conger Eel live?
Native to UK waters; most numerous along the south and west coasts of England, Wales, and Scotland, and all around the Irish coast, far less common on eastern coasts.
