Has 33-42 gill rakers on the first gill arch (Ref. 12693); 56-64 lateral line scales; the lateral line usually discontinuous; the dorsal profile almost arched as the ventral profile (Ref. 27732). |
| Occurs in shallow depths of large rivers (Ref. 12693). Found in slow flowing large rivers (Ref. 43281). Forms schools; often harvested in large numbers throughout its range. Feeds on zooplankton and occasionally on insects. Goes into flooded forests when water level is high and returns to the mainstream after the water level declines considerably (Ref. 12693). Spawning occurs at the onset of the flood season (May to July) and the eggs and larvae are swept downstream and out onto the flooded areas (Ref. 37770). Sometimes marketed fresh, but often used to make prahoc (Ref. 12693). |

Collected from Tha Ngon and Hatsalao in the Mekong basin (Ref. 4792). One of the most important fishes in the specialized "tone" trap fishery at Ban Hang Khone form January to March (Ref. 37770). This fishery mainly targets small highly migratory cyprinids (Ref. 37770). Reported to migrate upstream during the dry season in December/March in Southern Laos (Ref. 37769).
