A new analysis from our Center shows that the fish-farming industry is increasing its use of plant-based ingredients in its feed and moving away from traditional feed made from fish, which alters the environmental footprint of farmed fish and could impact some of the health benefits of eating certain types of seafood.

The Slow Food movement is embracing U.S. seafood with the 2016 Slow Fish conference in New Orleans, Louisiana.
