Straightfin Barb

Taxonomic Notes:

The genus Barbus (Cyprinidae) is restricted to a small number of species mainly inhabiting the European ichthyographic region including Northeast Africa. Most of the African species that are currently included in the genus, taxonomically do not appear to be closely related to the genus Barbus sensu strictu. However, no attempts have yet been made at an adequate nomenclature of the African forms. We therefore follow Berrebi et al. (1996) and use in this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished).Also reported under the names Barbus taitensis Günther, 1894, B. amphigramma Boulenger, 1903, B. macropristis Boulenger, 1904, B. thikensis Boulenger, 1905 and B. helleri Hubbs, 1918. All are junior synonyms (Seegers et al., unpublished).

Habitat and Ecology [top]

Habitat and Ecology:	A hardy species, preferring quiet, well-vegetated waters in lakes, and marshes or marginal areas of larger rivers and slow-flowing streams. Feeds on a wide variety of small organisms including insects, small snails and crustaceans, algae, diatoms, and detritus. Preyed upon by the sharptooth catfish, tigerfish, largemouth breams (Serranochromis species) and birds. Spawns amongst vegetation during summer (Skelton 1993) (after Froese and Pauly 2003). Spawning takes place up the influent rivers during the rainy season (January–February). Migration appears to correspond to periods of heavy rainfall or flushing. Fecundity ranges from 250–800 eggs per female of 50–60 mm SL up to 2,500 eggs per female of 112 mm SL. Max. size: 12 cm in length.
Systems:	Freshwater
