Comparison of the technology of aquaponic systems

Aquaponics is the combined culture of fish and plants in recirculating aquaculture systems, an ecologically sustainable horticultural production technique with long traditions.

The objective of this study is to compare flood-and-drain and a water crossflow system and examine the differences in the water quality, fish yield and plant growth parameters for Common carp and basil.

During the study, water quality parameters of two treatments were compared, temperatures, pH, EC and NO3¯ were significantly different. The leaf area of the basil plants grew to an average of 20.37 cm2. 

The plants' biomass production was significantly different in the two systems. The biomass production showed lower yield in the constant flow system than in the flood-and-drain system. 

Fish growth parameters were better in the constant flow system, although the specific growth rate demonstrated that fish grew faster in the flood-and-drain system.
