Abstrak: This study aimed to determine the effectiveness of the use of feed containing Allium sativum and Phyllanthus niruri to control bacterial diseases in catfish grow out. Catfish used in this experiment was as length as 7.27 ± 0.34 cm and as body weight as 0.51 ± 3.53 g. Catfish was maintained in plastic ponds with size of 2 m × 1 m × 0.5 m as many as 12 pieces. The treatments applied were Control (-) (without experimental feeding and without water changing), Control (+) (without experimental feeding and with water changing), Prevention (feeding with Allium sativum dose 1.4% and Phyllanthus niruri 0.7% before water changing for 21 days), medical treatment (feeding with Allium sativum dose 2.8% and Phyllanthus niruri 1.4% after water changing for 14 days). The results demonstrated that the survival in medical treatment reached 95.38% ± 7.43%, that was significantly different from control (+) treatment (P ≤ 0.1). Allium sativum and Phyllanthus niruri treatment with the dose of 2.8% and 1.4% were effective for bacterial disease control in catfish Clarias sp. grow out that showed the highest survival of 95.38%.

Abstrak: Motile Aeromonad Septicaemia (MAS) caused by Aeromonas hydrophila induced serious epidemics of ulcerative disease in walking catfish (Clarias sp.). Purpose of this research was to determine the effective dosage of Allium sativum and Pyllanthus niruri powders mixed in commercial feed with more applicable method in the field. The treatments tested were four different dosages of A. sativum and P. niruri powders, namely A (0,1%), B (1,1%), C (2,1%), D (3,1%) and control, namely K⁻ (without A. sativum and P. niruri powders, and injected with PBS 0,1 ml) and K⁺ (without A. sativum and P. niruri powders, and infected with A. hydrophila 0,1 ml). The treatments was given for two weeks before challenging test, at 15th day test in vivo carried out by injecting A. hydrophila (108 CFU/ml) into the fish by intramuscular and observed for 10 days. Parameters measured were survival rate, absolute growth, specific growth rate, clinical symptoms, wound healing, organs morphology, and water quality. Data were processed statistically using completely randomized design ANOVA single factor. The results showed that the survival of treatment K⁻ was 100±0,00%, C 60±20%, A 40±40%, B 40±40%, K⁺ 33,33±11,55%, and D 20±0,0% (p<0,05). The survival was not significantly different between treatment K⁻ and C. Thus C (2,1%) was effective and could be for preventing MAS in catfish (Clarias sp.).
