Gambaran Darah Merah Ikan Nila (Oreochromis Niloticus) Yang Diberi Pakan Mengandung Jamu Fermentasi Dan Diinfeksi Dengan Aeromonas Hydrophila
ABSTRACT
Herbs Fermented consist of Kaempferia galanga L, Curcuma xanthorrhiza Roxb, and Curcuma domestica Val are environmentally friendly disease prevention alternatives that can be added to feed, because they have several advantages, such as increasing appetite, digestion, growth, resistance to disease, and reduce stress levels in fish. This research was carried out in August-December 2021 at the Marine Science Biotechnology Laboratory and Fish Parasites and Diseases Laboratory, Faculty of Fisheries and Marine, University of Riau. The purpose of this study was to obtain the best dose from the addition of herbs fermented in increasing the immune system of Oreochromis niloticus as an effort to prevent diseases caused by Aeromonas hydrophila bacteria in terms of profile erythrocytes. The method used was an experimental method using a Completely Randomized Design (CRD) one factor, five levels of treatment, three replications so that 15 experimental units were obtained. The challenge test was carried out on the 32nd day using A. hydrophila with a density of 108 CFU / ml. The best dose was in P3 with dose of 200 mL/kg of feed which show total erythrocyte of 2.09x106 cells/mm3, hemoglobin level of 7.70 g/dL, hematocrit value of 37.70%, and shown a normal erythrocyte morphology. Water quality were ranged from temperature: 27-29oC, pH 6.9-7.2, DO 3.1-4.4 mg/L, and Ammonia 0.016-0.024 mg/L. Based on data obtained, it can be concluded that herbs fermented is able to increase the immunity of O. niloticus to disease caused by A. hydrophila.
