Hypsibarbus pierrei (SAUVAGE, 1880)

Yellow Eyed Silver Barb

SynonymsTop ↑

Puntius pierrei Sauvage, 1880

Etymology

Hypsibarbus: from the Ancient Greek ὕψι (húpsi), and the generic name Barbus, presumably in allusion to the deep body shape in members of this genus.

pierrei: in honour of “Pierre”, with no other information given, who collected the type. This is possibly botanist Jean Baptiste Louis Pierre (1833-1905), first director of Saigon Botanic Garden, who made many collections in tropical Asia.

Classification

Order: Cypriniformes Family: Cyprinidae

Distribution

Known from the middle and lower Mekong basins in Laos, Thailand, Cambodia, and Vietnam, plus the Dong Nai drainage in central Vietnam.

Type locality is ‘Rapids of Dang-nai, Bien Hoa Province, Thailand’, which corresponds to what is now the city of Biên Hòa in Đồng Nai province, southern Vietnam.

Habitat

This species is migratory on a seasonal basis; during the dry season it can be found in larger river channels, whereas during wetter months it moves to unknown spawning grounds. Apparently displays a preference for rocky habitats with flowing water, and is not known to adapt to reservoirs or other artificial impoundments.

Maximum Standard Length

At least 300 mm.

NotesTop ↑

H. pierrei is distinguished from congeners by the following combination of characters: 4 scale rows between lateral line and dorsal-fin origin; 6 upper transverse scales; 12-13 rakers on first gill arch; 15-19 serrations on spinous dorsal-fin ray; 14 circumpeduncular scale rows; 26-28 lateral line scales.

Hypsibarbus species are valued food fishes throughout their range although most species are thought to be in decline due to human activity, particularly damming of rivers and agriculture.

The genus is diagnosed as follows: two pairs of barbels; strongly serrated dorsal-fin spine; 8 branched pelvic-fin rays; skin of lower lip discontinuous with lower jaw, separated by a shallow groove; anal-fin base approximately 60% HL; scales with black margins resulting in reticulated appearance; fins often with extended falcate tips; anal and pelvic fins often brightly-coloured.

Missing information here? Our Knowledge Base is an ever-evolving work in progress, which naturally means that some species profiles contain more information than others. We're working on a daily basis to fill in all the gaps, so please have patience. This site relies heavily on the help of hundreds of people without whose valuable contributions it simply wouldn't exist. Information and photos regarding any freshwater or brackish fish species, its natural history or captive care is always much appreciated, so if you've anything you'd like to share please leave a comment below or email us.
