Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 19.2, range 18 - 20.235 cm
Max length : 32.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 7050); common length : 20.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 2686)
背的软条 (总数): 17-19; 臀鳍软条: 8. Distinguished from the other species of the genus in having 12-18 branched dorsal rays; 6-9 rows of spots along scale rows (not always distinct), and a large round blotch on the caudal peduncle (Ref. 27732). No black midlateral stripe; sometimes with a spot above a pectoral fin (Ref. 12693).
与本属的另一个种有 12-18个分枝的背鳍鳍条区分了; 6-9个列的斑点在尾梗上沿着鳞片列 (不常明显的), 与一个大的圆斑块。 (参考文献 27732) 没有黑色的侧面中央的斑纹; 有时有在一个胸鳍上面的一个斑点。 (参考文献 12693)
Adults occur in all type of habitats, but usually associated with large streams with slow current and muddy to sandy substrate (Ref. 27732). They migrate from river to flooded areas during the onset of the flood season and returns to river habitats at the end of that period (Ref. 37770). Juveniles are usually seen first in August, they move back to permanent water as flooded lands dry up. Back in the rivers they are attached to brush piles, tree roots and other solid objects (Ref. 12693). Adults feed on roots of plants (Hydrilla verticillata), unicellular algae and some crustaceans. Most abundant fish in Nam Ngum reservoir where it is captured with large dip nets set on rafts. Good flesh but bony and used for lap pa or grilled (Ref. 6459). Marketed fresh or used to make prahoc (Ref. 12693).
出现于所有类型的栖息地, 但是通常伴随着大的溪流且水流和缓底部泥泞多沙的地方.(参考文献 27732) 从河到洪泛区回游在的开始的时候洪水季节而且在那时期底回到河栖息地.(参考文献 37770) 在季节性浸水的区域中度过洪水季节。 稚鱼通常在八月被首先看到, 当被水淹没的土地变乾的时候，他们游回永久性水域。 他们被依附于灌木堆，树根与其他的坚硬目标回到河中。 (参考文献 12693) 在老挝河水库的最丰富的鱼在哪里它在筏上被用大的舀网捕获。 吃植物 ( Hydrilla verticillata) 的根，单细胞的藻类与一些甲壳动物。 也吃固着生物与浮游植物。 (参考文献 12693) 肉质佳但是多骨的而且用来 lap pa 或烧烤.(参考文献 6459) 在市场上销售生鲜地或者用来制造 prahoc 。 (参考文献 12693)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00762 - 0.01507), b=3.04 (2.99 - 3.09), in cm total length, based on LWR estimates for this species (Ref.
93245).
营养阶层 (Ref.
69278): 2.6 ±0.0 se; based on diet studies.
Generation time: 3.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
