大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 130 cm SL 雄魚/尚未辨別雌雄; (Ref. 7432); 最大體重: 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).
鰭深灰色或黑色的; 6個分枝的背鰭鰭條; 鰓耙通常發展; 幼魚有一條黑色的斑紋沿著側線與第二個長的黑色斑紋在側線下, 大的成魚均勻灰色.(參考文獻 12693) 在臀鰭的中央上的深色的斑紋; 在每個尾葉中的深色斑紋; 小的鰓耙經常地點綴著較大的一些了。 (參考文獻 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).
棲息於大河。 (參考文獻 12693) 雜食性 (參考文獻 6459), 吃魚與甲殼動物以及植物殘枝。 (參考文獻 12693) 一個迴游的種, 向上游來自後面沿岸區域到的未知的湄公河移動五月時產卵於未知的區域中-七月而且回到河水域落下尋找在九月 -十二月後面棲息地的主流.(參考文獻 37772) Khone 瀑布南方,溯溪迴游發生在十月到二月, 高峰期在十一月到十二月。 這遷移被水位退下引起而且在洪水季節結束的時候從洪泛區背面到湄公河在橫向的遷移之後狀似散佈遷移。 向下游的遷移在柬埔寨從 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。 在它被呈現出沒有斑紋失去稚魚的黑顏色與亞成魚，而且變成灰色的大的個體的湄公河中游中.(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)
