Common barbel
The common barbel, ''Barbus barbus'', is a species of freshwater fish belonging to the family Cyprinidae. It shares the common name 'barbel' with its many relatives in the genus ''Barbus'', of which it is the type species. In Great Britain it is usually referred to simply as the barbel; similar names are used elsewhere in Europe, such as ''barbeau'' in France. The name derives from the four whiskerlike structures located at the corners of the fish's mouth, which it uses to locate food.
==Distribution and habitat==
''B. barbus'' is native throughout northern and eastern Europe, ranging north and east from the Pyrénées and Alps to Lithuania, Russia and the northern Black Sea basin. It is an adaptable fish which transplants well between waterways, and has become established as an introduced species in several countries including Morocco and Italy.〔(【引用サイトリンク】url=http://www.fishbase.org/Introductions/IntroductionsList.php?ID=4472&GenusName=Barbus&SpeciesName=barbus&fc=122&StockCode=4670 )〕 Its favoured habitats are the so-called barbel zones in fast-flowing rivers with gravel or stone bottoms, although it regularly occurs in slower rivers and has been successfully stocked in stillwaters.
Barbel are very abundant in some rivers, often seen in large shoals on rivers such as the Wye.〔(【引用サイトリンク】url=http://wyeuskfoundation.org/navigation/otherfish.php )〕 Izaak Walton reported that there were once so many barbel in the Danube that they could be caught by hand, 'eight or ten load at a time' .
