Aquaculture has been spanning one of the fastest-growing animal food-producing sectors across the globe. Humans and fish have been inextricably linked for millennia, not only because fish is an important source of animal protein, providing many millions of livelihood means and food security, but also from an evolutionary viewpoint. In 2008, aquaculture accounted for 46 percent of the global food-fish supply, and per capita supply from aquaculture increased from 0.7 kg in 1970 to 7.8 kg in 2008, an average annual growth rate of 6.6 percent (FAO 2010). In developing countries, the sector contributes significantly to livelihoods and food security, especially in the Asia-Pacific region.
