Hunger and malnutrition remain among the most devastating problems facing the world’s poor and needy. With the world population expected to grow by 2.6 billion between 2005 and 2050 (roughly equal to the total global population in 1950 of 2.5 billion), there are growing concerns about the long term sustainability of many existing food production systems to meet future demands for food. Aquaculture is widely viewed as an important weapon in the global fight against malnutrition and poverty, particularly within developing countries where over 93% of global production is currently realised; the aquaculture sector providing in most instances an affordable and much needed source of high quality animal protein, lipids, and other essential nutrients.
