We addressed the challenge for agriculture of doubling food production while halving the footprint in our 2010 Feeding the Future booklet. Aquaculture has an equivalent challenge, though providing a far smaller proportion of the food needed by nine billion people in 2050 it still can be an important contributor.
Seafood is widely appreciated as tasty and excellent nutrition. However, the ocean fi sheries cannot increase yields without destroying the fi sh stocks on which they depend. Aquaculture must bridge the gap between sustainable fi sheries and global demand. Having grown rapidly over the past four decades, aquaculture already provides a substantial proportion of the fi sh, crustaceans and molluscs we eat. As contributors to this booklet discuss, for continued growth we require greater sustainability.
