Barbel Fish: ID, Size, Eating Risks and How to Catch

A barbel fish is a carp-family river fish, in Europe almost always the common barbel, Barbus barbus, named for the four whisker-like barbels around its mouth. The word comes from the Latin barba, beard (Wikipedia).

The name has two uses, which is why searches get confusing:

• Barbel the fish: Wikipedia describes the barbels as a group of carp-like freshwater fish, almost all in the genus Barbus. Across the group, lengths run from 25 to 240 cm and weights from 200 g to 200 kg; the biggest relative Wikipedia names, the Mangar or pike barbel, reached 198.5 kg (438 lb).
• Barbel the body part: the sensory whisker itself. Catfish, carp and many other fish have barbels without being 'barbel fish'. If your fish has whiskers but you are in North America, it is far more likely a catfish; see catfish species.

The common barbel is native to Europe from the Pyrenees and Alps east to Lithuania, Russia and the Black Sea basin, and has been introduced to Scotland, Morocco and Italy (Wikipedia). Its IUCN status is Least Concern.

Check these marks, taken from the Canal & River Trust and Wikipedia:

• Barbels: four, in two pairs; Wikipedia describes a longer pair pointing forwards and slightly down at the sides of the mouth
• Colour: golden bronze on the back and sides fading to a creamy white belly (Canal & River Trust); Wikipedia adds that adults can be dark brown, bronze or grey
• Fins: reddish-brown with an orange tinge; Wikipedia calls them distinctively reddish or orange-tinged
• Young fish: grey and mottled (Wikipedia), so a small barbel looks quite different from an adult

Look-alikes and the mark that separates them:

• Gudgeon: much smaller and has only 2 barbels (Canal & River Trust)
• Common carp: also has 4 barbels, but on the upper jaw, and a long dorsal fin with a saw-toothed spine in front (Missouri Department of Conservation); see common carp
• Catfish: smooth, scaleless skin (Missouri Department of Conservation), so a whiskered fish covered in scales is not a catfish

Photograph the fish flat on its side with the head in focus so the barbels and fin colour show. FishLens reads the photo and names the likely species; use the list above to confirm the result.

A barbel is not a catfish. It is a member of the carp family, Cyprinidae, in the order Cypriniformes (Wikipedia), the same family as the common carp. The only thing it shares with catfish is the whiskers, which many unrelated fish have.

It is also not the same fish as a common carp. Both are cyprinids with four barbels, but the common barbel is a long, streamlined fish of fast, gravelly rivers, while the common carp is a deep, stout-bodied fish (Missouri Department of Conservation).

Barbel are river fish. Wikipedia describes them in gravel- and rock-bottomed, moderately fast rivers with high dissolved oxygen, a stretch of river so typical of them that ecologists call it the barbel zone. The Canal & River Trust says they also turn up in slow or still water, especially canals that join rivers, such as the Kennet & Avon Canal between Kintbury and Reading.

In Britain the fish was once found only in east-coast rivers; the Canal & River Trust says it is now widespread, including the River Severn and River Trent, and Wikipedia notes it was historically moved between English rivers.

They feed on the bottom. The Canal & River Trust lists insect larvae, worms, crustaceans, snails and small fish; Wikipedia adds that young barbel eat diatoms and midge larvae. Wildlife photographer Jack Perks describes barbel using their barbels to taste the water and find food buried under gravel, such as caddis larvae, bullheads and worms.

• Spawning season: May to June on stones and gravel (Canal & River Trust); Wikipedia gives May to late June, after an upstream migration from March to May
• Eggs: a female produces up to 9,000 eggs about 2 mm across, which hatch in 10 to 15 days (Canal & River Trust)
• Maturity: 4 to 5 years (Canal & River Trust); Wikipedia splits it by sex, males at 3 to 4 years and females at 5 to 8
• Lifespan: 15 to 20 years (Canal & River Trust), over 20 years (Wikipedia)

The late maturity of females is one reason England protects river coarse fish in spring; see the close season below.

The main reason for caution is the eggs: Wikipedia describes barbel roe as highly toxic to people. Eating it causes an illness known as barbel cholera. A 2019 case report and review in Acta Biomedica (Comelli, Riccò and Cervellin) describes it as:

• Diarrhoea starting 2 to 4 hours after eating the eggs and lasting up to 12 to 36 hours
• Nearly always with vomiting and severe abdominal pain
• Usually self-limiting, but in rare cases massive diarrhoea can lead to a slow heart rate, very low urine output and shock

The authors note that even small amounts of roe can cause the full syndrome. Wikipedia adds that several well-known cookery writers have published barbel recipes, but we cannot tell you any wild fish is safe to eat.

If someone has eaten barbel roe, or any fish, and has vomiting, diarrhoea or dizziness, contact a doctor or your local poison control service; in the US that is Poison Control on 1-800-222-1222. Tell them the species and how long ago it was eaten.

Barbel are not shy, but they are hard to land. The Canal & River Trust calls them powerful fish and says a strong rod and a main line of at least 10 lb are a must. Wikipedia counts any barbel over 4.5 kg (10 lb) as a specimen fish.

Methods the Canal & River Trust describes:

• Modern: bolt rigs with pellets on a hair rig
• Traditional: a swimfeeder packed with hemp, with luncheon meat on the hook

Timing matters as much as tackle. In England the coarse-fishing close season runs from 15 March to 15 June on all rivers, streams and drains, and names barbel and chub among the fish it protects; it does not apply to most still waters and canals (Environment Agency, press release of 15 March 2018). Check the current rules for your water before you go.

Because they fight hard, barbel can be exhausted when landed. Our handling and release guide covers how to hold a fish in the water until it swims off on its own.
