Wild fisheries are essential to global food security but are facing immense pressure from overfishing to climate change. Aquaculture is now a major form of seafood production globally, but has thus far largely supplemented fisheries. In theory, aquaculture could be used to reduce pressures on wild-caught stocks by replacing some catch, reducing its reliance on wild aquatic feed, and optimizing wild seed sources. However, little effort has been given to reconcile fisheries sustainability with aquaculture expansion and food security. The Froehlich Lab is exploring the theoretical and practical potential of actively incorporating aquaculture into fisheries management for more sustainable seafood production.
