The purpose of this study is to investigate the growth of fancy carp and plants and variation of water quality using recirculating aquaculture system for application of aquaponic system. The concentrations of DIN and T-N at FCP(Fancy carp + Plant) condition were lower than that of FCO(Fancy carp only), because the nutrients was absorbed to the plants. However the other items of water quality were almost same regardless of plants because of water exchanging of 20 %. In this study we conclude that the exchanging of water is very important to maintain water quality for keeping ornamental fish. The length of fancy carp was grown to 7.9 % and 6.7 % at FCO and FCP condition and the weight was increased to 25.3 % and 21.7 % at each conditions. However there was not the significant differences between the existence and nonexistence the plants. The leaf height, root length, leaf number and weight of Scindapsus were grown to 3.3 cm, 11.9 cm, 2.2 pieces and 7.9 g. On the other hand, the lettuce was grown to two times as 13.7 cm, 16.1 cm, 10.2 pieces and 8.6 g Therefore, this study provide emotional stability by rearing fancy carp, breath clean air by keeping air purification plant such as Scindapsus and eat fresh vegetable such as lettuce by application of plants to recirculating aquaculture system.
