Aquaponics is the combination of aquaculture and hydroponics within a single system. You grow the plants (vegetables) hydroponically using the fish waste as the main source of nutrients. The plants in turn purify the water for the fish.
Notes on aquaponics are provided at www.aquaponics.co.za. Benefits of the system include:
- A small system can be fitted into backyards
- Low labour requirement
- No weeds or pests
- No soil cultivation necessary
- No wastage of water
- Fish waste utilised
- Higher yields and quality
- Constant production throughout the year
Ensure that you have a market for the organic produce (vegetables and fish) before you set up an aquaponic production system.
