Fisheries and Aquaculture
Aquaculture is on the increase on an almost global level, in terms of scale, intensity, and technology. The declining catch of wild fish on a global scale has meant that other sources of fish protein need to make up for the shortfall. This is the role that aquaculture is seeking to fulfill, but of course the location, type and species being cultivated have a massive impact on what the overall effectiveness of aquaculture is and will be.
Illustrated Handbook of Urban Aquaculture covers need and trends in urban aquaculture and aquaculture production, particularly concerning the development of aquaponics, and to compare the current production with fisheries potential. Food fish supply prospects will depend to a large extent on the effectiveness of aquaculture management and the responsible development of aquaculture, both of which will be tested in facing the sustainability challenge. An essential requirement for ensuring sustainable aquaculture through good policies and management will be the provision of objective information on the state of aquaculture. Parallel growth and shrinkage challenges cities and their citizens globally regarding a sustainable transformation of infrastructures and life-styles. Facing local fresh water, food and everyday resource provision the question arises, how can human- and ecosystem-related livelihoods and life-qualities be regenerated in a multifunctional manner? Water as a universal medium of life, transport and creation plays a key role within this change process.
This Illustrated Handbook of Urban Aquaculture presents state of the art topics on the key dimensions of urban food challenges and types of intra- and peri-urban aquaculture.
Aquaculture contributed 43 per cent of aquatic animal food for human consumption in 2007 (e.g. fish, crustaceans and molluscs, but excluding mammals, reptiles and aquatic plants) and is expected to grow further to meet the future demand. It is very diverse and, contrary to many perceptions, dominated by shellfish and herbivorous and omnivorous pond fish either entirely or partly utilizing natural productivity. The rapid growth in the production of carnivorous species such as salmon, shrimp and catfish has been driven by globalizing trade and favorable economics of larger scale intensive farming. The concept of Urban Farming has gained the serious attention of Planners and Academic communities in cities. The combined issues of Population explosion, rapid urbanization and climate change are posing great threat to the Food Supply. Urban Farming is seen to have potential for cities to have at least some measure of Food Security.
