The tambaqui (Colossoma macropomum) is a fish of primary importance in South American aquaculture, principally in the Amazon region and has a particularly unique diet in the wild. Oryza spp, or Wild rice as it is commonly known, is native to the floodplains of muddy rivers in the Amazon region. The aim of this study was to analyze the physical performance and the effects of dietary levels of Oryza spp. via the hematological parameters, total food intake, conversion efficiency, growth ratio and swimming performance of this fish. Diets containing 45% Oryza spp. induced the best performance in tambaqui. Diets containing 15% and 30% did not affect these indices, thus indicating that this amount of Oryza can be used as an alternative energy source for this important species within Brazilian aquaculture.

饲喂不同水平的水稻（Oryza spp）的丹巴基，巨像（Colossoma macropomum）的生长和血液学响应。

坦巴基（Colossoma macropomum）是南美水产养殖中最重要的一种鱼类，主要在亚马逊地区，在野外有特别独特的饮食。Oryza spp，或俗称野生稻，原产于亚马逊地区泥泞河流泛滥的平原。这项研究的目的是分析稻米的物理性能和饮食水平的影响。通过血液学参数，该鱼的总食物摄入量，转化效率，生长率和游泳性能。日粮中含有45％的Oryza spp。在tambaqui中表现出最佳表现。日粮中含有15％和30％的日粮对这些指标没有影响，因此表明该数量的Oryza可作为巴西水产养殖中这一重要物种的替代能源。
