The freshwater macrophytes are abundant in tropical and subtropical climates. These macrophytes may be used as feed ingredients for fish and other animals. The nutritional value of twelve freshwater-cultured macrophytes was evaluated in the present study. Significantly higher crude protein (36.94-36.65%) and lipid (8.13-7.62%) were found in and ; ash content was significantly higher in , and (20.69-21.00%) compared with others. The highest levels of sodium, magnesium, chromium, and iron levels were recorded in . was a rich source of copper, manganese, cobalt, and zinc; the contents of calcium, magnesium, strontium, and nickel were highest in . Selenium and potassium contents were higher in and , respectively. The n-6 and n-3 polyunsaturated fatty acids (PUFAs) contents were significantly higher in and , respectively compared with others. Linoleic and α-linolenic acids were dominant n-6 and n-3 PUFAs. The highest value (4.04) of n-3/n-6 was found in . The ratio ranged from 0.61 to 2.46 in other macrophytes. This study reveals that macrophytes are rich sources of minerals, n-6 and n-3 PUFAs.
淡水大型植物在热带和亚热带气候中十分丰富。这些大型植物可用作鱼类和其他动物的饲料原料。本研究评估了12种淡水养殖大型植物的营养价值。在[具体植物1]和[具体植物2]中发现粗蛋白（36.94 - 36.65%）和脂质（8.13 - 7.62%）显著更高；与其他植物相比，[具体植物3]、[具体植物4]和[具体植物5]的灰分含量显著更高（20.69 - 21.00%）。[具体植物6]中钠、镁、铬和铁的含量最高。[具体植物7]是铜、锰、钴和锌的丰富来源；钙、镁、锶和镍的含量在[具体植物8]中最高。硒和钾的含量分别在[具体植物9]和[具体植物10]中更高。与其他植物相比，[具体植物11]和[具体植物12]中n - 6和n - 3多不饱和脂肪酸（PUFAs）的含量分别显著更高。亚油酸和α - 亚麻酸是主要的n - 6和n - 3多不饱和脂肪酸。[具体植物13]中n - 3/n - 6的最高值为4.04。其他大型植物的该比例在0.61至2.46之间。本研究表明，大型植物是矿物质、n - 6和n - 3多不饱和脂肪酸的丰富来源。
