International Conference and Exhibition for Soilless Culture-2005 in Singapore from September 5 to 8.

Savidov and James Rakocy of the Agriculture Experiment Station of the University of Virgin Islands collaborated on the project. Dr. Nick Savidov, of the Crop Diversification Center South, Alberta Agriculture Food and Rural Development at Brooks, Alberta, Canada. Savidov is renowned for his 20 year research history in inorganic hydro. Dr. James Rakocy, is the leading researcher in aquaponics, with over 25 years of studying fish waste reuse and teaching at UVI.

Savidov spent two years research at Brooks comparing greenhouse growing of plants under both aquaponic and inorganic hydroponic regimes.

Tested five plants were heaving feeding greenhouse vegetables and 19 were herbs.

Based on those results Savidov says “I expect it to trigger a cascade of global interest in aquaponic technology. “

  • No wastewater – eliminates environmental damage risk (a costly expense only to become more a concern as regulations put into place further protecting the environment.)
  • Utilize sludge as worm food
  • More water efficiency than hydro
  • No costly hydroponic inorganic nutrients
  • Fish eat organic plant matter, larvae, worms
  • Possible unknown growth factor?
  • Dr. Savidov suspects one “may be playing a role in the performance of aquaponic systems. Aquaponics starts slower – but aquaponics leaps ahead after six months, yielding heavier cropping and earlier maturity. This is attributed to bacteria become more stable and effective at converting waste.
