Juveniles and subadults frequently found at river mouths and estuaries. They occur downstream from the first falls where the water is charged with mud and the bottom is muddy. In the Amazon, they can sometimes be caught in the upper part up to the foot of the Andean range where they appear 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). Flesh of excellent quality is highly appreciated.
