Occurs in upland reaches of the Mekong. Inhabits rocky stretches of the main stem of Mekong during the dry season and moves into tributary streams during high waters (Ref. 12693). Found in riffle and slow deep reaches (Ref. 37769). Herbivorous, feeding on algae, phytoplankton and periphyton. Not known to persist in impoundments (Ref. 12693). At Stung Treng below the Khone Falls, the species migrates upstream at the start of the rainy season in May-June and downstream in the dry season from November to February. At Sambor and Kratie as well as just south of Khone Falls, it moves downstream at the onset of the rainy season and upstream in the dry season. The reason for such movement seems to be the presence of the important tributary system, Sekong-Sesan-Srepok rivers. Fishermen reported that this fish migrates from this system into the Mekong during receding water and migrates upstream the tributaries during the rainy season, possibly to spawn. Upstream the Khone Falls, this fish begins migrating upstream in the dry season (February-May) and continues into the beginning of the rainy season. This movement may, in fact, be two separate migrations: a dry season non-reproductive migration of smaller fish and an early rainy season migration of larger fish in spawning condition. Undertakes upstream migrations from Khone Falls all the way to Chiang Khong in northern Thailand which are triggered by the increase of water levels and the change in water-color from clear to red-brown. Migrates upstream in schools together with other cyprinids such as Labeo cf. pierrei, Cirrhinus microlepis, Labeo chrysophekadion and Cyclocheilichthys enoplos as well as the loach, Botia modesta (Ref. 37770). Marketed fresh (Ref. 12693).
出现于湄公河的高地范围。 在高的水域的时候在乾季的时候栖息于湄公河的主流的多岩石的支流而且移入支流。 (参考文献 12693) 发现于急流与慢的深范围了。 (参考文献 37769) 食草的, 吃藻类，浮游植物与固着生物。 不知道持续在圈围水域中.(参考文献 12693) 在 Stung Treng ，在 Khone 瀑布之下，此鱼种溯河回游在那雨季的初始五月时-六月与向下游乾季时从十一月到二月。 在 Sambor 与 Kratie 以及正好向南方 Khone 瀑布，它移动下游在雨季的开始与向上游乾季时。 如此的运动理由似乎是那有重要的支流系统， Sekong-Sesan-Srepok 的河。 渔夫报告这一个鱼在雨季的时候在水位退下的时候从这一个系统到湄公河移动而且溯河回游支流, 可能地产卵。 向上游 Khone 瀑布, 这一个鱼进入雨季的起点之内开始向上游移动乾季时 (二月-五月) 而且继续。 这一次运动可能, 事实上, 是两个分开的回游: 乾季在产卵状况中的较小的鱼与较大的鱼早雨季迁移的非生殖洄游。 进行在泰国北部的来自 Khone 瀑布一路到清孔县的向上游的回游那是藉由引起水位与在水方面的改变增加-颜色从清澈的到红褐色的。 溯河回游成群伴随着其他的鲤鱼例如 Labeo 比较 pierrei ， Cirrhinus microlepis ， 黑野鲮［Labeo chrysophekadion］ 与 Cyclocheilichthys enoplos 以及泥鳅,橙鳍沙鳅［Botia modesta］ .(参考文献 37770) 在市场上销售生鲜地了。 (参考文献 12693)
