Aquaculture activity supplies high‐quality protein at affordable cost. A global call for foods of aquatic origin has heightened not only due to the zooming population growth, but also because of a choice of healthier foods for human beings. As the industry expands, it is facing the high cost of feeding because the key ingredients, that is fishmeal and fish oil, of aquadiet are very expensive. Identification of alternate foodstuffs that will remarkably minimize the expense of productivity of animal protein becomes a priority with due regard to environmental footprint. Alternative feed components are vital in partially or completely substituting unsustainable but high‐value components or constituents that will otherwise have direct competition with human use. Utilization of aquatic plants as a substitute for fish meal has the potential to revolutionize aquaculture in meeting global protein demand. A lot of money is spent on aquatic weed management, so this research idea tries to integrate both economic aspects and the environmental concerns. Macrophyte‐based feed ingredients have promising nutrient profile: crude protein ranges between 11% and 32%; lipid, 2.90% and 16.81%; and ash, 8% and 31%, a good array of amino acids; and a good amount of micro‐ and macronutrients that make them prosperous substituents for fish feed.

在未来的水产养殖中利用大型植物作为鱼类饲料原料的前景

水产养殖活动以负担得起的价格提供高质量的蛋白质。全球对水生食品的呼声日益高涨，这不仅是由于人口增长迅速，而且还因为人们选择了更健康的食品。随着该行业的发展，它面临着高昂的饲养成本，因为Aquadiet的关键成分（即鱼粉和鱼油）非常昂贵。在适当考虑环境足迹的情况下，识别可显着降低动物蛋白生产力成本的替代食品成为当务之急。替代饲料成分对于部分或完全替代不可持续但高价值的成分或成分至关重要，否则它们将与人类使用直接竞争。利用水生植物替代鱼粉有可能彻底改变水产养殖以满足全球蛋白质需求。在水生杂草管理上花费了大量资金，因此该研究思路试图将经济方面和环境方面的问题结合起来。基于大型植物的饲料成分具有良好的营养成分：粗蛋白范围在11％至32％之间；脂质2.90％和16.81％; 灰分分别为8％和31％的氨基酸；以及大量的微量元素和大量营养素，使它们成为鱼类饲料的繁荣取代基。粗蛋白在11％至32％之间；脂质2.90％和16.81％; 灰分分别为8％和31％的氨基酸；以及大量的微量元素和大量营养素，使它们成为鱼类饲料的繁荣取代基。粗蛋白在11％至32％之间；脂质2.90％和16.81％; 灰分分别为8％和31％的氨基酸；以及大量的微量元素和大量营养素，使它们成为鱼类饲料的繁荣取代基。
