The Potential Use of Acepromazine as a Transquilizer for Transportation of Catfish Juvenille
MetadataShow full item record
This study aimed to assess the potential use of acepromazine as a transquilizer in catfish juvenille (Pangasius pangasius) transportation with a different times of treatment (in the morning and afternoon). This research was conducted by using the method of soaking (dipping), mixing water with acepromazine. Experimental animals used were 600 catfishes, 3-week old catfish, with average body length about 5.08 cm, and body weight around 6 g. The experimental catfish were assigned into a completely randomized design with a 2x6 factorial arrangement. The first factor was soaking time consisted of two levels, morning and afternoon. The second factor was dose of acepromazine consisted of six levels, 0 ppm, 5 ppm, 15 ppm, 25 ppm, 35 ppm, and 45 ppm. Catfish were placed in a container containing 100 ml water and then mixed with acepromazine. When the fish showed the symptoms of anaesthesia, the fish were immediately placed into another container that contains water for the process of recovery. The symptoms of anaesthesia were observed, the decreases of body balance, reflex body, tonus muscle, and pain. Time needed by fish to recover was the duration of acepromazine. In addition, the mortality rate was also observed to document the safety of acepromazine as a transquilizer. The result showed that the effective dosage for used in catfish juvenille transportation were 25 ppm with time of treatment in the morning. This dosage was choosed because it had a faster onset (96,55 minute), a longer duration (81.76 minute), and a lower mortality rate (10%).
