Over the last four decades, the aquatic systems of the globe have undergone a rapid transition. Worldwide per capita fish consumption nearly doubled from about 8 kg in the early 1950s to 15.8 kg in 2006. Fish exports from the developing countries have surpassed export of traditional crops and meat. A study by the Food and Agriculture Organization (FAO) projects a global average per caput demand for all seafood to be about 18.4 kg by 2010 and 19.1 kg by 2015. The study also highlighted that developing countries already produce and consume more fish than developed countries and it predicts that the dominance of developing countries will grow further to 2020.
