These biophysical foundations have been incorporated into models of natural resource supply and of the relationship between energy use and economic performance. Cleveland and Kaufmann developed econometric models that explicitly represent and integrate the geologic, economic, and political forces that determine the supply of oil in the United States. Those models are superior in explaining the historical record than those from any single discipline. Larsson et al. also use energy and material flows to demonstrate the dependence of a renewable resource such as commercial shrimp farming on the services generated by marine and agricultural ecosystems.

Prawns and shrimps are the most widely cultivated crustaceans and are reared mainly in the warmer parts of the world using pond culture techniques. Prawn culture in Asia currently accounts for three-quarters of world production. The giant tiger prawn (Penaeus monodon) which weighs up to 500 g is reared in intensive systems both for the markets and as a valuable export commodity. Most large supermarket chains in the UK have this species on sale. Lobsters and crabs are also reared in captivity but on a much smaller scale. There are problems with aggression amongst adults and with successful rearing from eggs.
Although poverty may cause people to misuse resources, wealth also puts strains on resources by leading to increased consumption. Globalization of trade and markets has expanded production in some developing countries to meet international demand, often at the expense of biodiversity. Conversion of wetlands for shrimp aquaculture, deforestation for cattle, coffee, or soybean production are just a few examples of how globalization has contributed to biodiversity loss. Global markets also mean that consumers are often unaware of where the items they buy are from, or how they were harvested, though specialized labeling of food, paper, and wood products, sometimes called green-labeling or eco-labeling, can allow consumers to choose products that are managed sustainably. Markets do not necessarily reflect the full value of something or its full cost to the environment. Existing policies and government incentives often encourage overuse of resources. The phrase perverse subsidies was coined...
Gracilaria cultivation is mainly practiced in three dif ferent ways open water cultivation, pond culture, and tank culture. Open water cultivation is practiced in estuaries, bays, and upwelling areas. Gracilaria has been cultivated in ponds on a large scale only in China and Taiwan. Ponds are generally located in areas not exposed to strong wind, situated near the sources of both freshwater and seawater. Several species of economically important marine organisms (e.g., shrimp, crabs, fish, and prawns) are co cultured in the same pond at the same time - a type of polyculture integrated multitrophic system. The use of tanks may provide the greatest productivity per unit area and is more efficient than any other type of farming. In this type of system, several steps can be precisely controlled and managed to reduce the labor input, although this type of system has high operational (especially energy) costs. Tank systems may hold promise for the processing of nutrient enriched waters from...
