Objectives
1. Convert an existed hydroponics system to an aquaponics system for demonstration and training purpose.  The latter are a subset of the former and only the former is described.  Build the system with the number of holes for net pots determined by previous research (deliverable, number of holes for system).  Stock fish (deliverable, approximate biomass of fish (4 kg) per 100 plants).  Be sure aeration adequate (deliverable pump rate adequate for 4-6 ppm oxygen if DO meter available).  Choose a pump that exchanges about 1 grow bed volume of water per 24 hr (deliverable, measurement of flow rate extrapolated to 24 hr if time is available for extension agent to measure flow rate).  Building will be under the supervision of the extension agent and overall success will be the number of systems built and maintained.
2. Establish the biological requirement difference between two systems.  For farmers who wish to stop for a time at hydroponics, milestones will be figuring out fertilizer dilutions (ion profiles) and comparing by ICAES with theoretically optimal profiles as determined by previous research (deliverable, ion profile at start of growth).  For aquaponics systems see that systems operating optimally (deliverables dissolved oxygen levels in grow beds (at least 4 ppm) and nitrate levels in grow beds (200 ppm nitrate).  At the end of the hydroponics crop, check ion profile to be sure nutrients used up (deliverable ion profile).
3. Demonstrate the optimal feeding amount for the fish. Fish will be fed half maximal amounts (about 1% of bodyweight) for a month.  This will allow for establishment of nitrifying bacteria.  Chemical measurements need to be made to be sure that nitrate and dissolved oxygen levels are consistent with good crop growth (plant roots require oxygen for growth) and fish health.  At this point, we will transition to full ration fish feeding and make measurements to assure that nitrate and dissolved oxygen levels are consistent with full plant growth (deliverables, nitrate and dissolved oxygen levels).  Overall success of this objective will be production of produce in a timely manner.
4. Schedule planting, harvesting, replanting, and marketing for maximizing the yield.  Have discussions with each of the clients as to timing of planting and harvesting and replanting.  The goal is a constant supply of vegetables to eat or sell.  Commercial buyers are not tolerant with interrupted supplies of vegetables.  Deliverables, production of produce with a crop time of 7 weeks, harvest and use or sale once every 7 weeks.  Maintenance of markets
