Pengaruh Suplementasi Bakteri Asam Laktat Isolat UM 1 dan Inulin terhadap Kultur Benih Ikan Nila (Oreochromis niloticus)

Abstract

This study was conducted to see the effect of feeding in the form of Lactic Acid Bacteria (LAB) probiotic UM 1 Isolate and prebiotic (inulin) on survival, specific growth rate and feeding efficiency of tilapia fish (Oreochromis niloticus). The treatment consisted of control, probiotic, prebiotic and sinbiotic addition have been added to aquarium that contained 10 tilapia fish. This research was conducted at the aquarium (40 x 25 x 28 cm) for 21 days. The fish were treated by different probiotic types of for 15 days before being tested challenged. After that, the fish were challenged with pathogenic bacteria Aeromonas hydrophila. Observed for 5 days. The results obtained indicated that supplementation to the diet had no effect on the survival rate, specific growth rate and feeding efficiency of tilapia during the culture period, yet to yield significant results in improving the survival rate of fish after infected by Aeromonas hydrophila, namely the treatment of A ( control +) by 42%, treatment C (probiotic) by 89%, treatment D (prebiotic) by 85% and treatment E (sinbiotic) by 96%. The addition of probiotic, prebiotic and sinbiotic on feed can increase the survival rate of fish up to 54% due to infection of Aeromonas hydrophila.
