This species was first described by Sauvage in 1878. It belongs to the cyprinid family.
Native to Asia, it is found in fresh water under a tropical climate. It is essentially benthopelagic and potamodrome it is present in the Mekong basin where it occupies the basins or large rivers but also the uninhabited parts deepest of the Mekong.
An omnivorous species that feeds during the rainy season in floodplains of leaves, plants, lichens, phytoplankton, insects, litter and especially filamentous algae in the dry season.
A quick and fast-moving species that jumps over obstacles, breeds in the main streams, in wide, slow-flowing and moderate currents.
This fish is a migrant species that comes from Cambodia.
The species is characterized by :
a dorsal fin consisting of 15 to 16 soft rays, no backbone, 40 vertebrae, small scales between 53 and 60 on the lateral line.
The maximum length recorded to date is 65 cm in a male for a weight of 5 kg. During breeding trials at the “Ban Muang” site we were able to have a male with a maximum weight of 5.5 kg and a female of 6.5 kg. Males are generally smaller than females, their pectoral fins are rougher than that of females.
Juveniles have a silvery color with a red caudal fin. Sub-adults have purplish, bluish-blue head and body, and caudal fin rays are matt. The staining pattern is marked differently during migration.
This fish is a migrant species that comes from Cambodia. It spawns in March in Vietnam, running in April in Cambodia and from May to July in Laos, after laying the adults and juveniles down the current to reach the floodplains and during the rainy season (August to November, example in Cambodia plain flood of Tonle Sap Lake) as the waters recede, they join the rivers, this corresponds with the phases of full moon.
It is harmless, species not on the IUCN Red List UICN (International Union for the Conservation of Nature)
