Salmonids are the third major farmed finfish species after carps and tilapines, and thus contribute to global food fish production. However, as the aquaculture industry continues to grow, several challenges have emerged. Left unchecked, current problems will hinder aquaculture development. Metabolomics is one of the powerful biotechnological tools that will contribute to solving some of the pressing problems. This review aims to summarise findings and identify gaps from studies that used metabolomics in farmed salmon research. We extracted methodological information for comparison, highlighted analytical platform usages and identified most studied salmonids and sample types. We reviewed key articles to highlight the latest research themes. From the identified research gaps, future perspectives regarding potential use of metabolomics to solve issues in ecotoxicology, thermotolerance, nutrition, post-harvest quality, health and disease, and husbandry practices are provided. The survey also highlighted improvements in execution of metabolomics protocols in aquaculture.

鲑鱼水产养殖研究中的代谢组学：应用和未来展望

鲑鱼是继鲤鱼和罗非鱼之后的第三大养殖有鳍鱼类，因此有助于全球食用鱼的生产。然而，随着水产养殖业的不断发展，也出现了一些挑战。如果不加以控制，当前的问题将阻碍水产养殖的发展。代谢组学是强大的生物技术工具之一，有助于解决一些紧迫的问题。这篇综述旨在总结研究结果并找出在养殖鲑鱼研究中使用代谢组学的研究的差距。我们提取了用于比较的方法学信息，突出了分析平台的使用，并确定了研究最多的鲑鱼和样本类型。我们审查了关键文章以突出最新的研究主题。从确定的研究空白中，提供了关于代谢组学潜在用途以解决生态毒理学、耐热性、营养、收获后质量、健康和疾病以及畜牧实践等问题的未来前景。该调查还强调了在水产养殖中执行代谢组学协议的改进。
