Abstract

The objective of this research was to know water quality condition of nila fish rearing media (Oreochromis niloticus) feeded with gajah grass and kumpai grass formulae with or without probiotic enrichment. The current research has been done in the Basic Laboratory of Aquaculture and Laboratory of Microbiology, Agricultural Faculty of Sriwijaya University, from September to October 2007. Black nila fish fingerlings sized 5,5-7,2 cm were used in this experiment. The experiment was arranged in a Completely Randomized Design (CRD) with 7 treatments and 3 replications. The treatments tested were gajah grass and kumpai grass formulae without or with probiotic enrichment. The black nila fish fingerlings have been cultured in 50 cm x 45 cm x 40 cm aquarium for 26 days. Water quality parameters observed were temperature, pH, dissolved oxygen (DO), Biochemical Oxygen Demand (BOD5), carbondioxide (CO2), alkalinity, ammonia (NH3), nitrite (NO2"), nitrate (NO3*) and orthophosphate (PO4). The result of current research indicated that addition of Bacillus sp. probiotic to fish food formulae give good influences on water quality of nila fish conservancy media, namely improve DO, minimize contamination by lowering BOD5, ammonia, nitrite, nitrate and orthophosphate. Addition of Bacillus sp. probiotic tent to give unfavourable influences on water quality of nila fish conservancy media, namely to increase CO2 content and water alkalinity.
