其他摘要：ABSTRACT Outbreaks of infectious diseases due to Aeromonas hydrophila in catfish can cause high death rates (80–100%). Fish disease control can be done using phytopharmaceutical to prevent or treat diseases of fish. One of the phytopharmaceutical that known to prevent the fish diseases is ambon banana stem Musa cavendishii var. dwarf Paxton. This study was conducted to test the effectiveness of catfish immersion using banana stem juice as an immunostimulant against bacterial infections A. hydrophila . The observed parameters were a total performance of production, hematological test, and water quality. Immersion of catfish seeds with stem juice was performed at a concentration of 5 mL/L, 13 mL/L, and 21 mL/L for 30 minutes. Each treatment consisted of three replications. A total of 15 fishes were immersed in 1.5 L water. At day-9 after immersion, fish was infected by A. hydrophila bacteria at a dose of 10 4 cfu/mL. The results showed that fish treated with banana stem juice at a concentration of 13 mL/L had the survival rate of 53.33±6.67% which is higher than positive control (33.33±6.67%). Based on hematology observations on the 3rd day post-challenge test (H12) with A. hydrophila , total erythrocytes, hemoglobin, total leukocytes, phagocytic activity, differential leukocyte, and lysozyme activity was highest in treatment13 mL/L. Lower feed conversion ratio (1.08±0.04) were also obtained in treatment 13 mL/L. Thus Immersion of seeds in stem juice can boost the immune system against infections A. hydrophila .
