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).

  3. Supplement with calcium, potassium and iron
  4. Ensure good aeration
  5. Remove solids
  6. Be careful with aggregates
  7. Oversize pipes
  8. Use biological control
  9. Ensure adequate biofiltration
