Long-chain omega-3 fatty acids—eicosapentaenoic and docosahexaenoic acids—are essential components of human diets and some aqua and animal feeds, but they are sourced from finite marine fisheries, and are in short supply and deficient in large parts of the world. We use quantitative systems analysis to model the current global eicosapentaenoic acid/docosahexaenoic acid cycle and identify options for increasing supply. Opportunities lie in increased by-product utilization and food waste prevention. However, economic, resource, cultural and technical challenges need to be overcome.

量化全球 omega-3 脂肪酸循环的系统方法

长链 omega-3 脂肪酸——二十碳五烯酸和二十二碳六烯酸——是人类饮食以及一些水产和动物饲料的重要组成部分，但它们来自有限的海洋渔业，在世界大部分地区都供不应求。我们使用定量系统分析来模拟当前的全球二十碳五烯酸/二十二碳六烯酸循环，并确定增加供应的选项。机会在于增加副产品利用率和防止食物浪费。然而，需要克服经济、资源、文化和技术挑战。
