Abstract

Aquaculture is anticipated to play an increasingly important role in global food security because it may represent one of the best opportunities to increase the availability of healthy animal protein in the context of resource and environmental constraints. However, the growth and sustainability of the aquaculture industry faces important bottlenecks with respect to feed resources, which may be derived from diverse sources. Here, using a small but representative subset of potential aquafeed inputs (which we selected to highlight a range of relevant attributes), we review a core suite of considerations that need to be accommodated in concert in order to overcome key bottlenecks to the continued development and expansion of the aquaculture industry. Specifically, we evaluate the nutritional attributes, substitutability, scalability, and resource and environmental intensity of each input. On this basis, we illustrate a range of potential synergies and trade-offs within and across attributes that are characteristic of ingredient types. We posit that the recognition and management of such synergies and trade-offs is imperative to satisfying the multi-objective decision-making associated with sustainable increases in future aquaculture production.
