The New Alchemy Institute did a lot of research into aquaculture - small scale production of fish for eating. They found that a fish tank five feet in diameter and five feet tall can produce forty pounds of fish a year. (Meaning that you could have fish for dinner twice a week.) They perfected the method for growing tilapia, catfish or shrimp and even developed computer algorithms which could accurately predict the yield of fish based on variables [1].
Farm Fountain is 'a sculptural ecosystem you can eat'. The design, by Ken Rinaldo and Amy Youngs, is available under a Creative Commons license and their website gives instructions on how to build your own. The fish tank at the bottom produces edible fish and effluent-enriched water, which is circulated among the bottles above, where plants are grown hydroponically.
. Aquaponics is a sustainable and extremely resource-efficient method of food production, requiring no input but sunlight.
Algae could also be grown on the surface of the water, providing a source of food for the fish so that they would not require feeding. Many species of algae are also edible by humans.
