Barbonymus gonionotus (BLEEKER, 1849)
Barbus gonionotus Bleeker, 1849; Barbus javanicus Bleeker, 1855; Barbus koilometopon Bleeker, 1857; Puntius jolamarki Smith, 1934; ? Puntius viehoeveri Fowler, 1943
Barbonymus: from the generic name Barbus, to which members of this genus were previously assigned, and Ancient Greek ἀνώνυμος (anṓnumos), meaning ‘anonymous’, since this group of fishes had previously lacked a proper generic name.
Order: Cypriniformes Family: Cyprinidae
This species is currently accepted to have an enormous distribution that covers much of Southeast Asia including Cambodia, Laos, Thailand, Vietnam, Singapore, and Indonesia (Java and Sumatra). It is present in several major river systems including the Mekong, Mae Klong, and Chao Phraya, and appears to have been introduced to the Terengganu and Perak river systems in Peninsular Malaysia.
Type locality is ‘Indonesia: Java: Kalimas River [Brantas] in Surabaya’.
Mostly inhabits larger, slow-moving river channels that are prone to flooding during the wet season as well as their surrounding floodplains, but increasingly found in man-made canals and lakes. The fish move into inundated riparian areas and forests during wet periods to feed and spawn, returning to the rivers as the water begins to recede.
Maximum Standard Length
250– 300 mm.
