OPERATING AQUAPONIC SYSTEM IN BACLIEU UNIVERSITY

Abstract

This study was carried out to build a model of lifting and draining Aquaponics system and experimenting with different fish species (Microsynodontis armatus, Clarias. gariepinus, Oreochromis niloticus, và Channa striata) and plants (Ipomoea aquatica, L. siceraria, T. cucumerina, and C. sativus). The growth rates of fishes, plants and water environmental parameters (pH, temperature, NH₃, NO₂^-) in the Aquaponics system were recorded and evaluated during the experiment. The results showed that the four fishes observed in the experiments had high survival rates (>87%). The growth rate in weight was found highest in C. gariepinus (218.2±18.50 g) but lowest in M. armatus (29.95±1.73 g). The growth rate of O. niloticus, and Channa striata were 72.77±3.22 g and 84.55±5.42 g, respectively. The plants selected for testing in this Aquaponics system all grew well, without any pests or diseases. Generally, the environmental parameters surveyed in the Aquaponics model were in the suitable range for the growth of fish and plants.
