Scientists outline pathways to more resilient production

Aquaculture’s rapid expansion could be limited by its continued reliance on a fragile feed supply, according to a new study published in Nature Food. The analysis, conducted by researchers from Xiamen University, University of Massachusetts, Boston, University of Arizona, and University of Tasmania, found that despite major progress in using fishmeal and fish oil more efficiently, the aquaculture industry would need to secure an additional 1.8 million tonnes of alternative feed ingredients each year to keep pace with rising global demand for high-value farmed seafood such as salmon and shrimp.
