生物学特性     字汇 (例如 epibenthic)

Adults inhabit large streams and rivers (Ref. 12455). Fry occur at the mouth of small streams connected to larger rivers, where the bottom is muddy and with overhanging vegetation (Ref. 56749). Feeds on prawns (Ref. 56749). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). Fishermen along Kapuas in Indonesia observed that it used to form large migratory schools in Kapuas mainstream but such schools had become less noticeable, and this was attributed to intensive gill netting. Usually consumed fresh or processed as salted fish (Ref. 56749). Reaches more than 150 cm TL (Ref. 7050).

栖息于大的溪流与河。 (参考文献 12455) 进入被水淹没的森林。 (参考文献 9497) 在鱼上的一个夜行的掠食者.(参考文献 12693) 在湄公河中,这种游进内较小的溪流到产卵.(参考文献 37770) 卡普阿斯河的渔夫观察它用来了形式大的回游群游于卡普阿斯河主流但是如此的鱼群已经变得比较不易见,而且这被归因于密集的刺网。
