The production of farmed Atlantic salmon (Salmo salar) is currently linked to finite marine resources, particularly fish oil (FO) and fish meal (FM). Understanding this relationship in a quantitative manner is imperative if this critical balance is to be maintained within sustainable limits as the industry grows. Here we project the potential production and associated growth of the Atlantic salmon aquaculture industry on the basis of a variety of FO and FM utilization scenarios in aquafeed. Reducing FO and FM dietary inclusion to 3% each could permit production growth of 2% per year until the turn of the century (2097 and beyond 2100, respectively), independent of a host of alternatives now being utilized—with three portions of salmon per week providing almost all the recommended weekly long-chain omega-3 fatty acids for human intake. The Atlantic salmon industry’s positive annual growth can continue in an era of finite marine resource availability—without the need for additional finite marine resource inputs.

养殖大西洋鲑鱼（Salmo salar) 目前与有限的海洋资源有关，特别是鱼油 (FO) 和鱼粉 (FM)。如果要随着行业的发展将这种关键平衡维持在可持续的限度内，以定量方式理解这种关系势在必行。在这里，我们根据水产饲料中各种 FO 和 FM 使用情景预测大西洋鲑鱼养殖业的潜在产量和相关增长。将 FO 和 FM 饮食中的含量分别减少到 3% 可以使产量每年增长 2% 直到世纪之交（分别是 2097 年和 2100 年以后），这与现在使用的许多替代品无关——每份鲑鱼三份每周提供几乎所有推荐的人体每周摄入的长链 omega-3 脂肪酸。
