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