Aquaponic Biofloc Technology by Swamp Bacteria Probiotic for Clarias Catfish Rearing

Conventional catfish culture in Ogan Ilir (OI) have not optimal production, it can be increased by biofloc and aquaponics with local swamp bacteria as a starter. The purpose of this study was to apply technology combination aquaponic-biofloc increase the productivity (Clarias sp.) rearing. used two ponds, circular pond combined aquaponic (biofloqua) for months. results specific growth rate fish system were higher than that alone. survival during rearing months Biofloqua 100% while Biofloc 92-96%. water quality data measured temperature, 30.3–31.9oC, Dissolved oxygen 4.5–7.2 mg.l-1, pH 6-7, ammonia concentration 0.27-0.71 mg.l-1 29.5-31.3oC, 4.7-7.4 0.20-0.53 biofloqua system, respectively. floc volume formation alone reached 1.1 ml.l-1 per day, which above 0.42 due use nutrients plant growth. showed more performance both efficient feed (Food Conversion Ratio / FCR <1.00). Although 5% level t test no difference aquaculture biota between systems, an alternative farmer income harvesting vegetables together.
