水产饲料是利用水产养殖实现粮食生产可持续性的主要贡献者。因此，改善水产饲料的环境、经济和社会绩效为显著提高水产养殖实践的可持续性提供了机会，水产养殖实践构成了增长最快的食品部门。鱼粉和鱼油传统上是必需营养素的主要来源（例如，蛋白质和脂肪酸）。然而，供应价格的上涨和有限的自然资源（例如，饲料鱼）的减少鼓励了一些利益攸关方寻求其他营养丰富的选择。这项工作提供了一个多方面的评估，目前和有前途的未来水产饲料，利用多标准决策分析。所考虑的参数包括成本、环境影响和营养成分。根据不同利益相关者的观点得出的结果表明，用植物性豆粕替代鱼粉和用植物性菜籽油替代鱼油是所研究的提高水产食品生产中水产饲料整体性能的最有利替代品。
Aquafeed is a major contributor to the sustainability of food production using aquaculture. Therefore, improving the environmental, economic, and societal performance of aquafeeds provides an opportunity to significantly enhance the sustainability of aquaculture practices, which make up the fastest-growing food sector. Fish meal and fish oil are traditionally the main sources of essential nutrients (e.g., protein and fatty acids) in aqua diets. However, increases in supply prices and limited natural resources (e.g., forage fish) have encouraged some stakeholders to seek alternative nutrient-rich options. This work provides a multidimensional assessment of current and promising future aquafeeds, utilizing multi-criteria decision analysis. The considered parameters include cost, environmental impacts, and nutrient inclusion. The results based on varying stakeholders' perspectives indicate that the replacements of fish meal with plant-based soybean meal and fish oil with plant-based canola oil are the most favorable alternatives among those investigated to enhance the overall aquafeed performance in aquaculture food production.
