Effect Addition of Different Probiotic in Aquaponic Systems towards Water Quality in Aquaculture Catfish (Clarias sp.)

Abstract

Catfish (Clarias sp.) is a type of consumption fish have promising prospects because it has a high enough degree of market uptake. The high market demand which motivated farmers to develop farming aquaponics technologies. Aquaponics, in principle, in addition to conserve land and water use also increases business efficiency through the utilization of nutrients from food remains and fish for plant metabolism. Fish farming with high stocking density causes a decrease in water quality due to the accumulation of organic matter buildup of organic materials causing toxins in the water because there is ammonia (NH3) and nitrite (N02) on the water. The threshold for catfish ammonia content is <0.8 mg /L. Alternative to overcome the problem of water quality in aquaculture is the addition of probiotic. Probiotic contain several types of microorganisms that can help the process of decomposition of ammonia as a bioremediation agent for water quality control. The purpose of this research is to determine the effect of different probiotics in the aquaponics system to water quality. The method that used in this research is experimental with completely randomized design (four treat and five repeated) are P0 (control), P1 (probiotic A), P2 (probiotic B) and P3 (probiotic C). Analysis of data processed using Analysis of Variance. If there are significant differences then continued Duncan's Multiple Range Test. The results showed that the giving of probiotics in the aquaponic system is significantly different (p<0.05).The final conclusion is that the addition of probiotic in the aquaponic system affect the water quality. Based on the results of statistical analysis showed that the levels of ammonia, nitrite and nitrate was lowest for the treatment of P2 is 0.0204 mg /L, 0.012 mg /L and 2.731 mg /L. Ammonia, nitrite and nitrate is highest at P0 treatment (control) is 0.273 mg /L, 0.019 mg /L, 4.218 mg /L. Keywords : Aquaponic, Catfish, Probiotic, Ammonia, Nitrite, Nitrate, Clarias sp.

Dynamics of water quality in grouper nurseries with flow through, recirculation and bioremediation systems

“…The oxidation of waste products and the combustion of food, which generate energy for the life and growth of groupers, are influenced by the DO parameter. Nitrifying bacteria that exist in systems that demand oxygen depend on DO in the maintenance media using a recirculation system [27]. The DO value in the study was at the optimal value because of the use of an aeration blower to supply oxygen.…”

Microbubble Technology to Improve Growth of Catfish (Clarias sp.)

“…The recommended nitrite level for catfish farming is <1 mg/L (Kusumawati et al, 2018). Excess nitrite compounds in waters will reduce the ability of fish blood to bind oxygen (O2), because nitrite will react more strongly with hemoglobin which causes a high mortality rate (Pratama et al, 2017). The nitrate value obtained in the study was 7 mg/L-9 mg/L, this nitrate content was in an optimal state and good for the growth of aquatic biota which is supported by the statement of Adharani et al (2016) that the concentration of nitrate for growing catfish cultivation is a maximum of 20 mg/L.…”

“…Hasil pengukuran rata-rata nitrat, nitrit dan amonia berkisar 12,5 mg/l (Gambar 5), 0 -0,5 mg/l (Gambar 6) dan 0,003 -0,09 mg/l (Gambar 7). Nilai kandungan optimal untuk nitrat, nitrit dan amonia untuk budidaya sebesar <0,5 mg/L, <0,5 mg/L, dan < 1ppm (Pratama et al, 2017;Su et al, 2020;Zhang et al, 2020).…”
