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).
出現於湄公河的高地範圍。 在高的水域的時候在乾季的時候棲息於湄公河的主流的多岩石的支流而且移入支流。 (參考文獻 12693) 發現於急流與慢的深範圍了。 (參考文獻 37769) 食草的, 吃藻類，浮游植物與固著生物。 不知道持續在圈圍水域中.(參考文獻 12693) 在 Stung Treng ，在 Khone 瀑布之下，此魚種溯河迴游在那雨季的初始五月時-六月與向下游乾季時從十一月到二月。 在 Sambor 與 Kratie 以及正好向南方 Khone 瀑布，它移動下游在雨季的開始與向上游乾季時。 如此的運動理由似乎是那有重要的支流系統， Sekong-Sesan-Srepok 的河。 漁夫報告這一個魚在雨季的時候在水位退下的時候從這一個系統到湄公河移動而且溯河迴游支流, 可能地產卵。 向上游 Khone 瀑布, 這一個魚進入雨季的起點之內開始向上游移動乾季時 (二月-五月) 而且繼續。 這一次運動可能, 事實上, 是兩個分開的迴游: 乾季在產卵狀況中的較小的魚與較大的魚早雨季遷移的非生殖洄游。 進行在泰國北部的來自 Khone 瀑布一路到清孔縣的向上游的迴游那是藉由引起水位與在水方面的改變增加-顏色從清澈的到紅褐色的。 溯河迴游成群伴隨著其他的鯉魚例如 Labeo 比較 pierrei ， Cirrhinus microlepis ， 黑野鯪〔Labeo chrysophekadion〕 與 Cyclocheilichthys enoplos 以及泥鰍,橙鰭沙鰍〔Botia modesta〕 .(參考文獻 37770) 在市場上銷售生鮮地了。 (參考文獻 12693)
