Abstract:

The growths of Common carp (Cyprinus carpio) and Mint were evaluated in recirculating aquaponic system. Fish production, plant growth and nutrient removal were measured and their dependence on fish to plant component ratio were observed. Fish growth performance differed with different fish to plant component ratio. Fish growth was higher in 1:2 and 1:3 ratios, whereas, plant production was higher in 1:2 and 1:1 ratios. The ratios of fish to plant component were compared to balance the nutrient generation from fish with nutrient removal by plants. The optimum ratio obtained was 1:2 (fish: plant) which showed optimum fish production, plant growth as well as nutrient removal.
