Abstract/ Executive Summary:

Naturally diseased climbing perch Anabas testudineus was confirmed to be caused by Aeromonas hydrophila bacteria by aeromonas isolation medium (AIM), 0/129 vibriostatic agent and esculin hydrolysis. Such naturally diseased koi fish weretreated with four antibiotics: captor (chlortetracycline hydrochloride BP 45%), renamox 15% -Vet (amoxicillin trihydrate BP), oxy-Dox-F (oxytetracycline 20% and + doxycycline 10%), renaquine 20% -Vet (flumequine) at lower, recommended and higher doses were performed to examine the efficacy of the drugs. Captor was given at doses of 0.8, 1.0 and 1.2 g/3 litres of water separately. Doses of renamox 15% -Vet were given at 0.8, 1.0 and 1.2 g/litre of water. Doses of oxy-Dox-F were 0.8, 1.0 and 1.5 g/Kg body weight and doses of renaquine were 10, 12, and 15 mg/Kg body weight. Among the four antibiotics, effect of captor and renaquine at recommended dose showed the best result where 100% fish were recovered. However, renamox and oxy-Dox-F showed best result at higher dose.

Program Area: Animal Health and Management

Commodity: Koi/Climbing

Objectives:

1. The present work was undertaken to check the efficacy of four different well known antibiotics.

Methodology:

Experimental fish. A total of 24 naturally diseased climbing perch Anabas testudineus were collected from various parts of Tarakanda Upazila, Mymensingh district and observed for clinical disease symptoms. Secondly, the internal organs of representative fish were homogenized and 100 µl were plated and incubated to observe the growth of the pathogenic bacteria, for confirmation of the infection. Bacterial identification. Shortcut identification technique was adopted to identify the pathogenic bacteria. The colonies were sub-cultured on to Aeromonas isolation medium (AIM) plates. The grown colonies were tested with 0/129 vibriostatic agent and growth on esculin for the identification. Antibiotics tested. Four different types of antibiotic preparations were used in this study. The pharmaceutical company Novertis produced captor (chlortetracycline hydrochloride BP 45%) with a recommended dose of 1.0 g/3 litres of water for 5-7 days. Renamox 15% -Vet (amoxicillintrihydrate BP) with a recommended dose of 1.0 g/litre of water for 3-5 days, and renaquine 20% -Vet (flumequine) with 12 mg/kg fish for 3-5 days. ACI had oxy-Dox-F (oxytetracycline 20% + doxycycline 10%) with a recommended dose of 1 g/ 4 Kg body weight for 7-10 days. Experimental setup. The trial was conducted in twelve separate aquaria. For each drug, three aquaria were set for three different doses with two fish in each. The used doses of four different antibiotics are shown in Table 1.Each aquarium was filled with 20 litres of ground water and then antibiotics were added to the aquarium. Total medicinal trial period was 10 days. However, the recommended dosages were followed.

Achievement/Findings:

Aeromonas hydrophilawas confirmed as the etiology of Naturally diseased climbing perch Anabas testudineus. Such naturally diseased koi fish were treated with four antibiotics: captor (chlortetracycline hydrochloride BP 45%), renamox 15% -Vet (amoxicillin trihydrate BP), oxy-Dox-F (oxytetracycline 20% and + doxycycline 10%), renaquine 20% -Vet (flumequine) at lower, recommended and higher doses and among them captor and renaquine at recommended dose showed the best result. However, renamox and oxy-Dox-F showed best result at higher dose.
