Effectiveness of striped catfish (Pangasianodon hypophthalmus) cultivation in aquaponic system with three different plant against ammonia (NH3), nitrite (NO2), and nitrate (NO3)

Abstract

The purpose of this study was to determine which plants are effective and can affect the concentration of ammonia, nitrite, and nitrate in the cultivation of Striped Catfish in aquaponics systems. This research was conducted from 22 February to 23 March 2021 at the Faculty of Fisheries and Marine, Airlangga University, Surabaya using a Completely Randomized Design (CRD) research method with 4 treatments and 5 replications. The three plants used were kailan, lettuce, and pakcoy. One-way analysis (ANOVA) was used to compare the control group with the treatment at a significant level of P<0.05. Multiple Range Test (DUNCAN) was used to identify significant differences between the treatments. The results showed that the lowest concentrations of ammonia, nitrite, and nitrate were obtained by the treatment using lettuce plants with values ranging from 0.039-0.723 mg/L, 0.207-0.370 mg/L, and 6.181-9.923 mg/L, respectively.
