Maturity: Lm ? range ? - ? cm
Max length : 130 cm SL 雄鱼/尚未辨别雌雄; (Ref. 7432); 最大体重: 44.0 kg (Ref. )
Fins dark grey or black; 6 branched dorsal-fin rays; gill rakers normally developed; young with a black stripe along lateral line and a second long black stripe below lateral line, large adults uniformly grey (Ref. 12693). Dark stripe on the middle of anal fin; dark stripe in each caudal lobe; small gill rakers regularly interspersed with larger ones (Ref. 43281).
鳍深灰色或黑色的; 6个分枝的背鳍鳍条; 鳃耙通常发展; 幼鱼有一条黑色的斑纹沿着侧线与第二个长的黑色斑纹在侧线下, 大的成鱼均匀灰色.(参考文献 12693) 在臀鳍的中央上的深色的斑纹; 在每个尾叶中的深色斑纹; 小的鳃耙经常地点缀着较大的一些了。 (参考文献 43281)
Facultative air-breathing (Ref. 126274); Inhabits large rivers (Ref. 12693). Recorded as having been or being farmed in rice fields (Ref. 119549). Omnivorous (Ref. 6459), feeding on fish and crustaceans as well as on vegetable debris (Ref. 12693). A migratory species, moving upstream of the Mekong from unknown rearing areas to spawn in unknown areas in May-July and returning to the mainstream when the river waters fall seeking rearing habitats in September -December (Ref. 37772). South of the Khone Falls, upstream migration occurs from October to February, with peak in November-December. This migration is triggered by receding water and appears to be a dispersal migration following the lateral migration from flooded areas back into the Mekong at the end of the flood season. Downstream migration takes place from May to August from Stung Treng to Kandal in Cambodia and further into the Mekong Delta in Viet Nam. The presence of eggs during March to August from Stung Treng to Kandal indicates that the downstream migration is both a spawning and a trophic migration eventually bringing the fish into floodplain areas in Cambodia and Viet Nam during the flood season (Ref. 37770). Common in the lower Mekong, where the young are collected for rearing in floating fish cages. In the middle Mekong it is represented by large individuals that lose the dark coloration of the juveniles and subadults and become grey without stripe (Ref. 12693). One of the most important aquaculture species in Thailand (Ref. 9497). A photo of a 44 kg individual was said to have been featured in a Thai magazine (J.F. Helias, pers. comm., Fishing Adventures Thailand, e-mail: fishasia@ksc.th.com). Such a maximum weight also seems reasonable based on length-weight relationship for this species. Aquarium keeping: in groups of 5 or more individuals; not recommended for home aquariums; minimum aquarium size >150 cm (Ref. 51539).
栖息于大河。 (参考文献 12693) 杂食性 (参考文献 6459), 吃鱼与甲壳动物以及植物残枝。 (参考文献 12693) 一个回游的种, 向上游来自后面沿岸区域到的未知的湄公河移动五月时产卵于未知的区域中-七月而且回到河水域落下寻找在九月 -十二月后面栖息地的主流.(参考文献 37772) Khone 瀑布南方,溯溪回游发生在十月到二月, 高峰期在十一月到十二月。 这迁移被水位退下引起而且在洪水季节结束的时候从洪泛区背面到湄公河在横向的迁移之后状似散布迁移。 向下游的迁移在柬埔寨从 Stung Treng 到 Kandal 發生從五月到八月與進一步的進入越南的湄公河三角州之內。 那有卵在三月期間對從 Stung Treng 到 Kandal 的八月指出向下游的遷移是在洪水季節的時候最後進入在柬埔寨與越南的洪泛區區域的產卵迴游兼覓食迴游.(參考文獻 37770) 常見於下面的湄公河, 在哪裡幼魚為在漂浮的魚籠中後面被收集。 在湄公河中游中，它被呈現出沒有斑紋失去稚魚的深色顏色與亞成魚，而且變成灰色的大的個體。 (參考文獻 12693) 在泰國最重要養殖魚種之一.(參考文獻 9497) 44 公斤個體的一張相片被說曾經在一本泰國雜誌扮演重要角色 (J.F. Helias ， pers. comm。, 釣魚冒險泰國，電子郵件: fishasia@ksc.th.com). 如此的最大重量也似乎合理對於這個魚種以長度-重量的關係為依據。 水族館保持: 形成 5個或更多個體的群體; 不為家庭的水族箱魚推薦; 水族館最小體型 >150 公分.(參考文獻 51539)
