Aquaculture ranks as a phenomenal success story in global food production. In 1975, when I joined the SEAFDEC/AQD, aquaculture contributed 8% to the overall yield of the world's fish harvest; now it provides more than one-third of the yield of the world's fisheries. Total aquaculture production in 2003 was 54.8 million metric tons, valued at $67.3 billion in U.S. dollars. More than 90% of this output comes from Asia, where aquaculture has its origins. As with land-based agriculture, all of this aquatic food production and economic activity has come with environmental problems and social conflicts.
