aquaponics - the merge between aeroponics and aquaculture. Simply put. Fish tank water is filtered through grow beds and recirculated back into the
pond. Advantages over traditional methods is 15% of the water used by traditional growing, faster and denser growth of veggies, fish growth = to
amount of food given.
One 80 gal fish tank holds at least 80 up to 160 fish ie.. talapia harvestable in 7 months avg 1 lb. this tank feeds two 4x8 grow beds. Replensh water
at 1% per week = a gallon. No weeds to pull. Much fewer pests to control. 15 mins/ day to test temp/water variables. NO pesticides allowed since they
would kill the fish! In fact only use natural ph adjustments if necessary.
An Aquaponic farm of 2 acres with 12 greenhouses in the east us produces enough food to feed 2000 people a year. Try that with agriculture!
Tom once calculated the farm produces 45 to 70 pounds of produce for every pound of tilapia, an impressive yield. However, Paula explained this figure
takes into account the cumulative yields of multiple vegetable crops raised during the 7- to 12-month time period required to raise fish to
