<![CDATA[Aeromonas hydrophila is a pathogenic bacterium that frequently attacks, causes death, and harms catfish farmers. The continuous use of antibiotics for disease control has been shown to have negative impacts on pathogenic bacterial resistance, antibiotic residues in fish, aquatic environmental pollution, food safety, and causes allergies in human consumers. The use of phytopharmaceuticals is known to be more environmentally friendly and sustainable because they contain active compounds that are more easily degraded, thus leaving no synthetic antibiotic residues in fish tissues and water. This research aimed to determine the effect of black turmeric (Curcuma aeruginosa Roxb) rhizome ethanol extract on treating A. hydrophila infection in catfish. Fish were raised for 14 days. For the first seven days, they were kept under normal conditions. On day 7, the fish were infected with A. hydrophila. On day 8, the diseased fish were immersed in black turmeric rhizome ethanol extract. The experiment used group randomized design with treatment of control or without black turmeric extract (BT0), 35 mg/L, 40 mg/L and 45 mg/L black turmeric extract (BT35, BT40, and BT45). The result showed that treatments were not significantly different (P>0,05) on recovery rate, survival rate, and WBC, but significantly different in hematocrit percentage (P<0,05). The highest of fish recovery rate and survival rate (100%) were obtained in BT40. This research concluded that immersion dosage of 40 mg/L black turmeric rhizome ethanol extract could treating catfish infected with A. hydrophila.]]>
