The growth performance and muscle quality of tilapia (Oreochromis niloticus) were compared between a fish-rice co-culture system (SD3) and a monoculture system (CG3). Tilapia with initial mean weight of 10 g and mean length of 5 cm raised in improved water quality produced by the co-culture system (SD3) showed better growth parameters, as well as better proximate composition with higher protein and lower lipid content. The free amino acid composition of tilapia muscle in SD3 were better than that of CG3. The major nucleotide (adenosine monophosphate (AMP) and inosine monophosphate (IMP)) contents of SD3 were significantly higher, while the major organic acid contents (acetic acid and malic acid) were lower. In SD3 the muscle fiber area was higher but the muscle fiber density was lower than in CG3. Finally, the SD3 fish had enhanced umami, sweetness, and overall flavor, and less of an earthy-musty taste compared to CG3. Overall, the co-culture of tilapia and rice improved the growth performance and muscle quality of tilapia via improved water quality and rich microbes in rice field. This was conducive for providing fish with high quality.

罗非鱼（Oreochromis niloticus）的生长性能和肌肉素质。）在鱼米共培养系统（SD3）和单养系统（CG3）之间进行了比较。共培养系统（SD3）产生的改善的水质使罗非鱼的初始平均重量为10 g，平均长度为5 cm，该生长的罗非鱼显示出更好的生长参数，以及具有更高蛋白质和更低脂质含量的更接近的组成。SD3中罗非鱼肌肉的游离氨基酸组成优于CG3。SD3的主要核苷酸（单磷酸腺苷（AMP）和肌苷单磷酸（IMP））含量明显较高，而有机酸（乙酸和苹果酸）的含量较低。SD3中的肌肉纤维面积较高，但肌肉纤维密度低于CG3。最后，与CG3相比，SD3鱼的鲜味，甜味和整体风味均得到增强，并且具有泥土味的味道。总体而言，罗非鱼和水稻的共培养通过改善稻田中的水质和丰富的微生物改善了罗非鱼的生长性能和肌肉品质。这有利于为鱼类提供高质量。
