Abstract

Catfish is a leading commodity in the fisheries cultivation sector, one of the main problems in catfish cultivation activities is infection with Motile Aeromonas Septicemia (MAS) disease caused by the bacteria Aeromonas hydrophilla. This study aims to determine the therapeutic activity of young teak leaf (Tectona grandis) solution against Aeromonas hydrophila bacteria and to find the most effective dose of young teak leaf (Tectona grandis) solution in inhibiting the performance of Aeromonas hydrophila bacteria. using a completely randomized experimental design with 4 treatments and 3 replicates conducted over 19 days. The fish were injected intramuscularly with a concentration of 10⁶ cfu/ml (0.1 ml) and subjected to treatments A (Control), B (10 g/L), C (15 g/L), and D (20 g/L). The fish were immersed for 20 minutes. The results obtained from the study were analyzed using analysis of variance (ANOVA). The results of the study showed that herbal therapy by soaking catfish in a solution of young teak leaves was effective in treating catfish infected with A. hydrophila at the optimal dose, namely in treatment B (10 g/L), which was characterized by a decrease in the number of bacteria calculated using the ALT method of 0.06 x 10⁷ in the kidneys and 0.02 x 10⁷ in the liver, as well as a survival rate and a cure rate of 100%. The results of this study are expected to be easily implemented and beneficial for fish farmers.

Abstract

Catfish is one of the superior fisheries sectors in the market, but the obstacle often faced by catfish farmers is disease attacks. One of the diseases that often attack catfish is the Aeromonas hydrophila bacteria. An alternative that can be used in the treatment of bacteria in catfish is to utilize antibacterial compounds found in noni fruit (Morinda citrifolia). The purpose of this study was to determine the effective dose of noni fruit solution soaking in the treatment of catfish infected with Aeromonas hydrophila bacteria. This study used a completely randomized experimental design method with 4 treatments and 3 replications carried out for 17 days and was infected intramuscularly with a concentration of 106 CFU/ml of 0.1 ml, with test treatments A (Control), B (30 g/L), C (45 g/L) and D (60 g/L) and soaking using the short bath method for 20 minutes. The results obtained from the study will be subjected to analysis of variance (ANOVA). The results of the study showed that the effective dose was found in treatments B (30 g/L), C (45 g/L) and D (60 g/L) with the observed variables of fish recovery and survival rates being 100%, while the optimal dose for reducing the number of bacteria was found in treatment B (30 g/L) in the kidney section of 0.72 x 107 with a reduction of bacteria of 76.8% while in the liver section it was 0.57 x 107 with a reduction of bacteria of 80.1%.
