Asia: endemic to the Mekong.
亞洲: 湄公河的特有種。
大小 / 重量 / 年齡
成熟度: Lm ? range ? - ? cm
Max length : 150 cm SL 雄魚/尚未辨別雌雄; (Ref. 30857); 最大體重: 70.0 kg (Ref. 10431)
背的軟條 (總數) : 13; 臀鰭軟條: 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.
Body shape (shape guide): fusiform / normal.
有別於兩者其他種的 Probarbus 有些微比較小的 (與眾多的) 的鱗片, 在背鰭起點與側線鱗片列 6 之間的鱗片列; 六只在側線之上的身體上取代五條斑紋; 唇明顯增大; 縮小的長觸鬚,有時不存在; 而且約略更很多的脊椎骨。 下唇的後緣完全地與到側邊的側邊分離。
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).
出現於大的高地河川。 吃底棲的生物與昆蟲幼生。 (參考文獻 58784) 對於這種由於所知極少過去與 P. jullieni 混淆. 顯然地移動伴隨著 P. jullieni 而且已經被大量滅絕在寮國南部被在 Lee Pee 瀑布的正上方針對那種的藉由密集的刺網漁業.(參考文獻 10431) 然而, 發現需要進一步的調查是否它分享相同的產卵場與產卵時間.(參考文獻 10431)
