Aquaponics Seeking Sustainable Agriculture Solutions

Aquaponics
Aquaculture
Aqua (latin) - water
Culture - agriculture
Hydroponics
Hydro (greek) – water
Ponos (greek) - labor

Aquaculture
Aquaculture accounted for 47 percent of fish consumed in 2006
Waste, antibiotics, competition/invation, and habitat loss or destruction
Wastewater often high in nitrates

Hydroponics
Constant need to monitor/alter pH, non-sustainable nature of many growing media, and high cost of equipment and maintenance
Disposal of tremendous amounts of chemical wastewater
Harsh chemicals:
Ingestion can result in gastrointestinal distress, with abdominal pain, lethargy, nausea,vomiting, diarrhea, blood chemistry effects, cardiac effects, and central nervous system effects.

Aquaponics
One process can be used to aid in solving the problems of the other
Nitrates that result from fish waste are utilized by the plants, and as long as the plants continue to remove the nitrates from the water to keep the fish healthy, the fish will continue to supply the plants with this food source

Nitrogen Cycle

Growing Power
Perch & Tilapia
Tank is 4-5' deep, and is dug right into the floor of the greenhouse
Grow both in gravel media and pots with coir and compost

My Experiment
