Abstract/ Executive Summary:

This study was carried out at the Disease Laboratory of the Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh, Bangladesh to verify the therapeutic performances of six commercial aqua drugs; three doses were selected as less than recommended, recommended and more than recommended to assess their performances. Before starting therapeutic experimental nine climbing perch (Anabas testudineus) and six stinging catfish (Heteropneustes fossilis) were confirmed as diseased ones by their clinical signs. The back swimmers (Notonecta glauca) were collected from faculty of fisheries pond and fish louses (Argulus sp.) were collected from tilapia fishes. Effective doses and their performances were determined on the basis of desired water quality change and clinical signs. It was found that all the drugs performed better at more than recommended doses as follows Aqua Ox performed better at the rate of 0.2 mg/l, GR Plus, 0.0005 ml/l, ID Plus (5%), 0.00026 ml/l; Active Blue, 0.0002 ml/l; Hashpoka Killer, 0.0001 ml/l; and Para Control, 0.001 ml/l. So these doses were suggested as recommended doses.

Objectives:

To verify the therapeutic performances of aqua drugs for developing the water quality and disinfectants,
To cross check the suggested doses and dosages of the drugs and
To identify the problems associated with their doses.

Methodology:

The experiment was carried out in the Disease Laboratory of the Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh, Bangladesh. The research work was undertaken in 12 glass aquaria (average capacity 30 liter), the aquaria were checked carefully for any leak. After that each aquarium was filled with 30 liter of tap water and 30 liter of pond water. Each aquarium was provided with aerator for continuous oxygen supply. Six aquaria were used for treatment of selected aqua drugs. An adequate level of dissolved oxygen in each aquarium was maintained through artificial aeration during the experimental period. Diseased climbing perch (Anabas testudineus), the stinging catfish (Heteroneustes fossilis) the back swimmer (Notonecta glauca) and fish louses (Argulus sp.) were selected for the experiment. Diseased fish were collected from the ponds of the Faculty of Fisheries of Bangladesh Agricultural University campus and nearby fish farms; after collection those were carefully transported to avoid physical injury. The back swimmers were collected from the experimental ponds and fish louses were collected from naturally infected diseased Tilapia (Oreochromis niloticus) fishes from different places of Mymensingh district. There were six aqua drugs used in this study viz; Aqua Ox for increasing the oxygen level, G. R. Plus for maintaining the ammonia level, ID Plus (5%) and Active Blue as disinfectants and Para Control or Hashpoka Killer as parasite killers. Water quality parameters were evaluated before and the resultant parameters, after doses aqua drugs treatment with a certain time interval were conducting the experiment. On the basis of resultant water quality change, the efficiency of the drugs was worked out and requisite doses were determined. The measurement of water quality and sample collection dissolved oxygen was measured done between 28 hours at 2 hour’s time intervals, and measured ammonia by 8 hours 1 hour intervals by using different testing kits and instrument. Ammonia (mg/l), dissolved oxygen (mg/l), pH and temperature were measured. Determination of disinfectants were conducted to investigate, in laboratory condition, the two products ID plus (5%) and Active Blue those were strong disinfected performances against bacteria and fungus causing infectious diseases. In climbing perch (Anabas testudineus) was collected from south side of Faculty of Fisheries pond, BAU campus and stinging catfish (Heteropneustes fossilis) were collected from local fish farm. Fish were acclimatized for 3 days in laboratory condition.

Achievement/Findings:

The best result was obtained with 100% recovery of infected fish when the disinfected, ID plus (5%) was used at a higher dose (0.00026ml/l) and recommended dose (0.00013ml/l) and lower dose than recommended dose (0.00007ml/l) showed two fish were not recovered in laboratory condition. And ID plus (5%) was used at a higher dose (0.00026ml/l) and recommended dose (0.00013ml/l) and lower dose than recommended dose (0.00007ml/l) showed two fish were not recovered in laboratory condition. Hashpoka Killer resulted in 71.33%, 92.67%, 96.33% mortality at 0.00005ml/l, 0.000083ml/l, and 0.0001ml/l. Para Control for 19 minutes was found to be 100% effective in killing Argulus sp. at recommended dosage (0.000843ml/l).
