“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.”
How to Clean, Dress, and Filet Fish…and the tools and utensils needed:
This last part is just the credits.
“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.”
Francis Hill farms in Waboden, Manitoba, Canada. Here she shares a tip for using fish guts and bones to fertilize potato plants. She gets the fish bits from anglers.
Apparently fish are a great fertilizer. With all the contamination that has been showing up in ocean and especially in freshwater fish I would probably feel a little nervous about this method.
