Is Rooftop Fish Farming The Future For Locally Grown Fish?

Rooftop farm

Rooftop farming has proven that the top of buildings are great places to grow food, utilize space, and cut down food miles. However, this new idea might sound crazy to even the most innovative green thinkers: rooftop fish farming.

Antonio Scarponi and Conceptual Devices have created a prototype rooftop fish farm design, made as a “bamboo greenhouse designed to organically grow fish and vegetables on top of generic flat roofs.”

An aquaponic farming technique was used to fuel the idea, where the fish feed off the plants and the plants clean the water for the fish. So far, the system is designed to produce 400 kilograms of veggies and 100 kilograms of fish, which can feed four families of four members year–round.

In the summer, the dome-like structure harvests tomatoes, eggplant, squash, cucumber, and melons, and in colder seasons grows carrots, broccoli, cabbage, and peas. Several fish species such as salmon, tilapia, and trout are grown.

The structure runs on minimal resources to keep it as environmentally friendly as possible, and can even be equipped with solar panels and cooling turbines. Water from the tank pumps into the upper grow bed, which trickles down into the lower grow beds. Clean water is then pumped back into the tank, creating a loop that recycles as many resources as possible.

Roofs will not need any structural changes in order to support the tank, which is built out of completely biodegradable and sustainable organic bamboo. Beds can be easily installed in varying formats to cater to a building’s environmental needs. Apparently, it’s even easy to have shipped right to your door, with everything packing right inside the tank for easy transportation.

Scarponi is hoping to sell the tanks for about the same price as a small car, making it affordable and easy to make up the cost. If it gets past the concept stage and is available to building owners around the world, it will could make eating locally and sustainably much easier for many people.

If you own a business, or even a home, would you ever consider installing a rooftop fish farm?

    I just finished watching Simon Reeve’s odyssey around the Indian Ocean and am now deciding to be off fish unless it is sustainably caught, so this seems to be a wonderful idea.  The Hawaiians had a sustainable practice through constructing fishponds (some still exist and are in working order), and they regularly forbade fishing in areas where it seemed fish stocks were being depleted, but with no one really in charge of who catches what in the ocean, we all need to be much more mindful of making sure we protect and preserve our oceans and its inhabitants.
