Jose Villalon, Director of WWF-US Aquaculture Program, says "Farmed fish is an excellent source of protein and, when produced well, helps protect the environment. I am totally convinced that aquaculture is the most sustainable way to feed the world."

Seafood is one of the most healty and popular sources of protein worldwide. Seafood is widely recognised as good nutrition by health authorities, dietary specialists and many others. As governments and food and health advisory bodies in Europe and the USA are actively encouraging their populations to include more fish in their diet, consumption of seafood globally is expected to continue to rise.
Almost half of the seafood eaten comes from farms, making aquaculture the fastest growing food production system in the world. All food production systems have an environmental impact, however, when done responsibly, aquaculture’s impact on wild fish populations, marine habitats, water quality and society can be minimal. Aquaculture holds great promise to produce seafood of high quality and large volumes.
