Barbels are a group of carp-like freshwater fish, almost all of the genus Barbus. They are usually found in gravel and rocky-bottomed moderate-flowing rivers with high dissolved oxygen content, known as the Barbel zone. A typical adult barbel can range from 25 to 240 cm (9.8 to 94.5 in) in length and weigh between 200 g (7.1 oz) and 200 kg (440 lb), depending on species.
The name barbel derived from the Latin barba, meaning beard,[1] a reference to the two pairs of barbels, a longer pair pointing forwards and slightly down positioned, on the side of the mouth.
Fish described as barbels by English-speaking people may not be known as barbels in their native language, although the root of the word may be similar. For instance, the Mediterranean barbel (Barbus meridionalis) is known as barbeau méridional or barbeau truité in France, but also as drogan, durgan, tourgan, turquan and truitat.[2]
