生態學
; 淡水 底中水層性; 河川洄游 (Ref. 51243). 熱帶
Asia: endemic to the Mekong basin where it has become rare due to overexploitation.
亞洲: 湄公河流域的特有種在那裡它已經變得稀有由於過漁。 國際間的買賣禁止 ( 引用 I, 自從 1.7.1975 以後; 公分 附錄 I).
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 300 cm TL 雄魚/尚未辨別雌雄; (Ref. 30857); 235.0 cm SL (female); 最大體重: 350.0 kg (Ref. 43281); 最大年齡: 10 年 (Ref. 116372)
背棘 (總數) : 2; 背的軟條 (總數) : 7 - 8; 臀鰭軟條: 35; 脊椎骨: 48. Body without stripes; posterior nostril located near anterior nostril; 7 branched dorsal-fin rays; gill rakers rudimentary or absent; fins grey, never black (Ref. 12693). The center of the eye above the horizontal line through the mouth angle in juveniles; eye totally below the level of mouth angle in subadults and adults. The maxillary and mandibulary pairs of barbels well developed in juveniles; mandibulary barbels become rudimentary in subadults and adults (Ref. 9448). Gigantic size; oral teeth and gill rakers present in small juveniles, absent at about 30-50 cm SL; dorsal, pelvic and pectoral fins without filamentous extensions (Ref. 43281). Distinguished from other large catfish in the Mekong by its lack of teeth and the almost complete absence of barbels (Ref. 2686)
身體沒有斑紋; 後鼻孔位於前鼻孔附近了; 7個分枝的背鰭鰭條; 鰓耙不發達的或不存在; 鰭灰色的, 從不黑色的.(參考文獻 12693) 在稚魚中經過嘴巴角的在水平線上面的眼的中心; 眼完全地在嘴角的水平之下在亞成魚與成魚中。 在稚魚中的上頜骨與下顎對觸鬚發展良好的; 下顎觸鬚在亞成魚與成魚中變成不發達。 (參考文獻 9448) 巨人般的大小; 口部的齒與鰓耙出現在小的稚魚, 於大約 30-50 公分 SL 不存在; 背部的, 沒有絲狀的延長的腹鰭與胸鰭.(參考文獻 43281) 用它的缺乏齒與在湄公河中的其他大鯰魚區分了，而且幾乎完全者缺乏觸鬚 (參考文獻 2686)
Facultative air-breathing (Ref. 126274); A migratory species (Ref. 37772) which occurs in medium to large-sized rivers (Ref. 12975). Feeds on detritus and algae on the bottom (Ref. 58784); feeds only on vegetation in the river but takes other food in captivity; little is known on its general pattern of life and migratory journeys for spawning (Ref. 2686). Shows one of the fastest growth rates of any fish in the world, reaching 150 to 200 kg in 6 years (Ref. 12693). Cited in the Guinness Book of Records as largest freshwater fish (Ref. 6472). Marketed fresh (Ref. 12693). Maximum length of 300 cm needs confirmation. Threatened due to over harvesting and habitat loss (Ref. 58490).
一個迴游的種 (參考文獻 37772) 出現於中到大型的河中。 (參考文獻 12975) 吃碎屑與在底部上藻類;(參考文獻 58784) 在河中只吃植物但是吃其他食物在繁殖場; 少為人知在它的一般生活型態與產卵迴游的路程。 (參考文獻 2686) 顯示任何魚的最快速成長率之一世界上, 在 6 年中達到 150 到 200 公斤.(參考文獻 12693) 在金氏世界記錄中引用如大的淡水魚。 (參考文獻 6472) 在市場上銷售生鮮地.。 (參考文獻 12693) 300 公分的最大長度需要證實。 受威脅的捕穫之上由於與棲息地損失.(參考文獻 58490)

50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00386 - 0.01562), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.

營養階層 (Ref.
69278): 2.3 ±0.17 se; based on food items.
Generation time: 12.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
