Monthly (April 2009 to May 2010) bottom-trawl sampling for Brachyplatystoma species along the rapids stretch of the Madeira River in Brazil revealed that Brachyplatystoma rousseauxii larvae and juveniles were present in low abundances in all areas and during all hydrological periods. The presence of larvae and juveniles throughout the hydrological cycle suggests asynchronous spawning in the headwaters of the Madeira River.
2009年4月至2010年5月期间，每月在巴西马德拉河急流段对巴西真鲷属物种进行底拖网采样，结果显示，在所有区域和所有水文时期，鲁氏巴西真鲷的幼体和幼鱼数量都很少。在整个水文循环中都存在幼体和幼鱼，这表明马德拉河上游存在异步产卵现象。
