Juveniles and subadults frequently found at river mouths and estuaries. Occurs downstream from the first falls where the water is charged with mud and the bottom is muddy. In the Amazon, it can sometimes be caught in the upper part up to the foot of the Andean range where it appears to be more rare than Brachyplatystoma filamentosum and Brachyplatystoma flavicus but never in the zones prone to flood. Reproductive migrations probably occur like in other Brachyplatystoma (Ref. 35381). Usually caught with longlines and drift nets (Ref. 35381). Its flesh of excellent quality is highly appreciated.
稚魚與亞成魚時常發現於河口與河口了。 生存來自水是充滿泥巴的最下面與底部是泥濘的地方的下游。 在亞馬遜河，它有時能被在上半部捕獲向上到安第斯山脈範圍的腳在那裡它狀似比 絲條短平口鯰〔Brachyplatystoma filamentosum〕 更稀有與 Brachyplatystoma flavicus 但是從不在區域中有洪水的傾向。 生殖迴游可能出現相似的在其他的 Brachyplatystoma 中.(參考文獻 35381) 通常用延繩釣與流網捕獲了。 (參考文獻 35381) 它的優良品質的肉高度地被欣賞。
