【 摘 要 】

Intensive catfish [Clarias gariepinus(Burchell, 1822)] cultivation produces organic waste that decreases water quality. The aquaponics system utilizes fish waste for plant growth to produce useful and economical products. This study aims to analyze and evaluate the best density of Mexican sword plant/water Jasmine [Echinodorus palaefolius (J. F. Macbr.)] in reducing waste from intensive catfish aquaculture. The research method used a completely randomized design (CRD) with four treatments with three replications. A plastic tub with a size of 38 cm × 12 cm × 30 cm filled with sand was used for plant media, while for catfish rearing containers, a 70 L tub with a water volume of 40 L was used. The fish used in this experiment were catfish fry with a size of 7 cm ± 0.8 cm, a weight of 5.14 g ± 0.45 g, with a stocking density of one fry per liter. Catfish fry were fed with floating pellet feed of 30 % protein content, and the feeding was done at satiation. The –2 –2 –2 treatments were T1 = without plants, T2 = 150 g m plants, T3 = 250 g m plants, and T4 = 350 g m plants. Furthermore, all data were analyzed through ANOVA (One-way analysis of variance) and the Duncan’s multiple range test to measure significant variations among the treatments using SPSS (version 17, USA). The results revealed that T4 was the best treatment in terms of nutrient removal efficiency of TAN, NO , NO and PO at the rate of 23.80 %, 48.19 %, 52.99 % and 2 3, 4 26.11 %, respectively. Moreover, growth performances of fish fry fed diet in T4 also were significantly (P < 0.05) higher than other fishes of different treatments. Regarding these findings, E. palaefolius could work well to maintain water quality during C. gariepinus cultivation and even accelerated C. gariepinus growth at the end of the period.
