Abstract
Aquatic animals and plants have been used for integration of aquaculture with hydroponic system by applying various designs. The plant nutrients were properly managed for the integration of aquaculture with hydroponics by using closed as well as recirculating system. Both Paddy rice and catfish are common Cultivated by farmer in Indonesia. However, integrating Padi Rice and Catfish using aquaculture-hydroponic systems rarely focused based on research. These research was carried out in the fish pond of the Agriculture Faculty, Tadulako University. It was carried out in the form of an experimental design using the split-plot method consisting of 2 (two) factors. The first factor as the main plot is the catfish population density- K0 (control), K1 (150 population/m3), K2 (300 population/m3) and K3 (450 population/m3). The second factor as a sub-plot is the ratio of organic media composition between husk charcoal and compost- M1 (1:1), M2 (1:2) and M3 (1:3). The results showed that the rice growth and yield increased linearly with increasing catfish population combined with more amount of compost media (K3M3). The Integration of Rice hydroponics system with catfish cultured in Aquaculture could be applied in integrated farming system
