Aquaculture and aquaponics on a family-sized scale in Maui, Hawaii. They are growing mainly tilapia whose waste they filter out and use to grow food plants.

“Rob Torcellini bought a $700 greenhouse kit to grow more vegetables in his backyard. Then he added fish to get rid of a mosquito problem and before long he was a committed aquaponic gardener. Now his 10 by 12 foot greenhouse is filled with not only vegetables, but fish. And the best part is: the poo from that fish is what fertilizes his garden.”
“Milwaukee’s Growing Power, a community-based urban food center, is using plants as natural water filters for raising yellow perch. Fred Binkowski, an aquaculture specialist with the University of Wisconsin Sea Grant Institute, provides technical advice on the experimental effort.”
“Aquaculture (i.e. aquatic plants and animals) is North America’s third largest import, only following automobiles and fuel. However, we have managed to overfish our environment beyond repair. Overfishing poses an enormous threat to our oceanic ecosystems. Enter urban aquaculture, or more simply put: fish farming in the city.
Because urban aquaculture raises their fish rather than collecting them in mass quantities from their natural habitat, it provides an opportunity for fish levels and ecosystems to return to a healthier state.
Professor Martin Schreibman, distinguished Professor Emeritus of Biology at Brooklyn College, has developed a state-of-the-art, sustainable urban aquaculture facility. His aquaculture utilizes a water re-use system. Fish waste is filtered out and is used as a plant fertilizer, so ultimately, he is self-sustainably harvesting 2 types of crop — fish and plants.”
