European Eel

One of Europe's most mysterious freshwater fish, the European eel spends most of its life in rivers, canals, and coastal wetlands before making a single, one-way migration across the Atlantic to spawn in the Sargasso Sea.
Native to Atlantic Europe and the Mediterranean basin, it's a nocturnal bottom-dweller that rewards patient anglers willing to fish after dark with a muscular, writhing fight unlike anything else in freshwater.
Scientific Name: Anguilla anguilla
Also known as Eel
- Snake-like body covered in a thick mucus layer rather than visible scales; dorsal, anal, and caudal fins merge into a single continuous fin running the length of the body.
- Color shifts with life stage: the long-resident 'yellow eel' is brown-yellow overall, while the maturing 'silver eel' develops a silver belly and noticeably enlarged eyes.
- Lower jaw projects slightly forward; small pectoral fins sit just behind the head; pelvic fins are absent entirely.
- Most fish run 35–50 cm (14–20 in) and 1–2 kg (2–4 lbs), but females can reach 133 cm (4 ft 4 in) and over 6 kg (14 lbs).
What to know
Habitat Distribution
- A catadromous species — born at sea in the Sargasso Sea, it migrates into freshwater to grow, then returns to the ocean once to spawn and die.
- Native across Atlantic Europe from Scandinavia to Morocco, including the Baltic, Mediterranean, and Black Sea drainages; introduced in parts of Asia and Central and South America.
- Turns up in a wide range of water types: rivers, canals, lakes, lagoons, wetlands, and brackish coastal areas — essentially any connected water it can reach.
- Tolerates temperatures from 4°C to 20°C (39–68°F) and can be found from the shallows down to 700 meters in coastal zones.
Specific Spots
- Roots, undercut banks, submerged timber, and dense weed beds are where eels spend daylight hours — bait presented tight to these features after dark is the standard approach.
- Muddy, sheltered sections of river or canal hold more eels than clean gravel runs; the softer the bottom, the more likely an eel is using it as a daytime refuge.
- On lakes and ponds, the deepest, most sheltered bays with soft substrate concentrate fish, particularly where inflowing water carries food.
European Eel FAQ
Answers from onWater's species guide.
What are the best lures and bait for European Eel?
Lobworms and clusters of smaller worms are the go-to bait across all water types, presented on the bottom, they match the invertebrates eels naturally root out of sediment. Dead baits, sections or whole small fish, account for the largest eels, which increasingly target fish as they grow.
What do European Eel eat?
Worms are the backbone of eel fishing for a reason, lobworms and worm clusters match the invertebrates eels root through bottom sediment to find, and they're the most consistently effective bait across all water types.
Where do European Eel live?
A catadromous species, born at sea in the Sargasso Sea, it migrates into freshwater to grow, then returns to the ocean once to spawn and die.
