Analysis of feeding habits was performed for early life stages of Brachyplatystoma rousseauxii and Brachyplatystoma filamentosum in the Madeira River, Brazil. Stomach contents of B. rousseauxii and B. filamentosum were identified and analysed to provide the percentage of frequency of occurrence (%FO) and area (%A) and the alimentary index (IAi). The order Diptera represented the most important item consumed by both species. This is the first analyses of the trophic ecology of these ecologically and economically important species of the Amazonian region in early life stages.
对巴西马德拉河的鲁氏真巨脂鲤和丝尾真巨脂鲤幼鱼阶段的摄食习性进行了分析。对鲁氏真巨脂鲤和丝尾真巨脂鲤的胃内容物进行了鉴定和分析，以得出出现频率百分比（%FO）、面积（%A）和食物指数（IAi）。双翅目是这两个物种消耗的最重要食物种类。这是对亚马逊地区这些具有生态和经济重要性的物种幼鱼阶段营养生态学的首次分析。
