Abstract

Abstract: The purpose of this research was to know the combination effect of Bacillus spp., Nitrosomonas sp., that added to the commercial feed to feed conversion and growth on Sangkuriang Catfish. The method used in this experiment was design with 3 treatments and 3 replications. Samples (24.49±1.21 g) were a stocking density of 1, 500 fish/pond and maintenanced for 30 days. The treatment applied was P0 treatment (feed without probiotic), P1 (5.0 x 10 7 CFU/gram feed of probiotic was sprayed), and treatment P2 (5.0 x 10 9 CFU/gram feed of probiotic is sprayed). The best treatment was probiotic in treatment P1 quantitatively made a real effect in growth and made a better feed efficiency than other treatments, with FCR (0.7±0.57), SGR (4.33±0.11), EPP (109.61±9.69), SR (96.91±0.45), DWG (2.07±0.18). Water quality of culture media was in the range of reasonable level of cultivation C. gariepinus . Adding probiotic P1 could be an effective alternative to increase growth performance and feed efficiency on C. gariepinus .
