Definition should include aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails, or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically-grown plants, where nitrifying bacteria convert ammonia into nitrates, and detailing the types of aquaponics systems, such as
- Nutrient film technique (NFT)
- Deep Water Culture (DWC)
- Media Bed
- Decoupled
Definition should include
- site selection
- water sources/availability (management)
- climate
- topography
- location/facility (e.g., greenhouses, warehouses)

- essential equipment (e.g., lighting, water quality test kits, irrigation systems)
- maintenance
- preventive controls/biosecurity
- advantages of aquaponics
- disadvantages of aquaponics
- species selection
- tilapia
- ornamental (e.g., koi)
- stocking densities
- factors of production.
