Fishery products are the world's most important source of animal protein especially for the poor. Meeting the basic human needs for protein foods in the future will be a difficult challenge especially as demand for fish has doubled since the 1950s. Realistically we can not expect to catch more food from the sea so we must now turn to farming the waters not just hunting them. The new challenge for planners is to accelerate aquaculture development and to plan for new production. As millions of people are moving from rural inland areas to coastal cities we need to make urban areas not only centres of marketing and distribution but also of production particularly using recycled urban wastewater. This book on urban aquaculture includes papers from authors in the USA Europe and Asia that review these emerging issues from the perspective of both developed and developing countries.
