The UVI Aquaculture Program has developed a commercial-scale aquaponic system that produces 5 MT of tilapia annually (harvest at 6-week intervals) and a variety of vegetables (harvest lettuce weekly or as required for other crop types).
Principles of aquaponics - by Dr. James Rakocy
- Use a feeding rate ratio for design calculations
- Keep feed input relatively constant
- Supplement with calcium, potassium and iron
- Ensure good aeration
- Remove solids
- Be careful with aggregates
- Oversize pipes
- Use biological control
- Ensure adequate biofiltration
- Control pH
