Aquaponic system combined recirculation aquaculture and agriculture，which roduct crops and aquatic products at the same time. Intelligent aquaponic aquaculture automatic monitor the system important factors (including temperature，pH，Disolved oxygen，EC etc.)，and reduce manpower demand. By cloud platform，the management could know the system status whenever necessary. The system factors recorded also can offer to the expert to make the system better.This year we configures a set of the auto monitor equipment to environment factor in aquaponics system (Contain water temperature，pH and DO，EC and temperature，humidity and precipitation and Light accumulation etc.)。In the system，carry on the monitor to the environment factor of the aquatic products and the crop growth and it's right to carry on the ratio with general examination result .Slightly have the difference as a result，but difference all less than 4% . During experimental perio,we also conducted an experiment to investigate the effect of different culture densities on hydroponic plant growth. The results showed that the concentrations of nitrogen, phosphorus and kalium were higher in high density system than low density system, but the harvest amount did not increase correspondingly.
