Tricia gives you a quick overview of aquaponics and aquaponic systems such as deep water culture, flood drain tables, and dutch buckets:
20,000 lbs of Fish + 70,000 Vegetables per 1/4 Acre ... Portable Farms Aquaponics - YouTube http://buff.ly/1gRen13
One of the most robust and scalable Aquaponics system in the world is the "Portable Farms". Maxed out, you could produce 240,000 vegetables and 92,000 pounds of fish per acre, using up to 95% less water and no dirt.
Aquaponics is the combination of aquaculture (fish farming) and hydroponics (growing plants in water only), in a closed-loop system.
Using this system, each 25 SF of grow space can feed one adult 25% of their protein and all of their table vegetables, year round.
Note: The system may not be that efficient after all. Check the comment under the YouTube video.
