簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 3 - 4; 臀鰭軟條: 79 - 96. Differs from its sole congener, B. dinema, in having a shorter pectoral fin, 21.9-25.8% SL, versus 25.9-28.9; a shorter head, 20.9-23.9% SL, versus 24.2-26.0; and a shorter snout, 35.4-39.6% HL, versus 39.0-43.1 (Ref. 38432). Strongly compressed head and body; upturned mouth with conspicuous large teeth; pectoral fin longer than head (Ref. 43281).
有別於它的唯一同類， B. dinema, 在有一個方面較短的胸鰭， 21.9-25.8% SL, 對 25.9-28.9; 一個較短的頭部， 20.9-23.9% SL, 對 24.2-26.0; 而且一個較短的吻， 35.4-39.6% HL, 對 39.0-43.1.(參考文獻 38432) 非常扁長形的頭部與身體; 朝上的嘴部具有顯著的大齒; 胸鰭長度超過頭部.(參考文獻 43281)
Occurs in medium to large-sized rivers (Ref. 12975). Found from middle depths to the surface in deeper parts of large rivers. Feeds on smaller fish near the water surface. An excellent game fish which can be caught using hook and line. Presently large numbers are being taken near Stung Treng in Cambodia by explosives (Ref. 12693). Migrates upstream through the Khone Falls in June-July with other silurids and enters the flooded forest in July-October, where it feeds heavily on cyprinids of the genus Henicorhynchus (pa soi, identified as Cirrhinus spp.) (Ref. 38432). Marketed fresh or dried and salted (Ref. 12693).
以其他的鯰魚溯河迴游在六月到七月的經過 Khone 瀑布而且進入在七月-十月被水淹沒的森林, 在那裡它吃經常捕食本屬 Henicorhynchus 的鯉魚 (pa soi,鑑定為 Cirrhinus spp了.)。
