大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 150 cm SL 雄鱼/尚未辨别雌雄; (Ref. 30857); 最大体重: 70.0 kg (Ref. 10431)
背的软条 (总数): 13; 臀鳍软条: 8; 脊椎骨: 40 - 41. Differs from the two other species of Probarbus in having slightly smaller (and more numerous) scales, scale row between dorsal fin origin and lateral line scale row 6; six instead of only five stripes on body above lateral line; lips greatly enlarged; barbels reduced in length, sometimes absent; and slightly more numerous vertebrae. Posterior margin of lower lip entirely free from side to side.
有别于两者其他种的 Probarbus 有些微比较小的 (与众多的) 的鳞片, 在背鳍起点与侧线鳞片列 6 之间的鳞片列; 六只在侧线之上的身体上取代五条斑纹; 唇明显增大; 缩小的长触须,有时不存在; 而且约略更很多的脊椎骨。 下唇的后缘完全地与到侧边的侧边分离。
Occurs in large upland rivers. Feeds on benthic organisms and insect larvae (Ref. 58784). Undergoes upstream movement for spawning (Ref. 58784). Little is known about this species due to past confusion with P. jullieni. Apparently migrates together with P. jullieni and has been decimated by the intensive gillnet fishery directed at that species just above the Lee Pee Waterfalls in southern Laos (Ref. 10431). However, further investigation is needed to find out whether it shares the same spawning grounds and times (Ref. 10431).
出现于大的高地河川。 对于这种由于所知极少过去与 P. jullieni 混淆. 显然地移动伴随着 P. jullieni 而且已经被大量灭绝在老挝南部被在 Lee Pee 瀑布的正上方针对那种的藉由密集的刺网渔业.(参考文献 10431) 然而, 发现需要进一步的调查是否它分享相同的产卵场与产卵时间.(参考文献 10431)
