Abstract

Anesthetic method is an important component to support the activities of transporting live fish from one place to another for a long period of time. Cost efficiency and effectiveness of anesthetic ingredients that not cause residues in fish are factors to beconsidered as an anesthetic. Aim of this research is to study the effect of subletal concentration of amethyst leaf extract on the hematological conditions of tilapia fry after transporting on wet transportation systems. The research procedure was through the amethyst leaf extract toxicity test series (LC50-96 hours) to determine its sublethal concentration by 20% (0,297 ml/l), 30% (0,445 ml/l) and 40% (0,594 ml/l) of the LC50 value. The measured parameters are clinical symptoms, period of fainting and conscious recovery, hematological analysis, survival rate, and water quality. The results showed the concentration of amethyst leaf extract had an effect (P<0,05) on the period of fainting and the hematological component after transportation simulation. Results of water quality measurement showed the parameters of pH at 6 and ammonia 0,04 mg/l are not at the optimum value when fish transportation occur. The recommended concentration of amethyst leaf extract for use as an anesthetic agent is 0,445 ml/l

Abstract

Nile Tilapia (Oreochromis sp.) is one of the freshwater fishery commodities that has high economic value and wide adaptability to various environmental conditions. This fish is known to be able to survive in varying temperatures and water qualities, and it has a fast growth rate. Therefore, it is widely cultivated on both an industrial and household scale. This study evaluated the growth and survival of tilapia (Oreochromis sp) in a gallon-based aquaculture system for 30 days at the Experimental Pond, Aquaculture Study Program, Faculty of Agriculture, Sriwijaya University. Two groups with uniform feed and density were observed for growth in length, weight, survival rate (SR), and water quality. Results were showed a survival rate of gallons A 33.3%, absolute length 2.4 cm and absolute weight 3.27 g. Meanwhile, the survival rate of gallons B 91.6%, with absolute length of 2.73 cm, and absolute weight 2.54 g. Water quality throughout cultivation was in an optimum range for temperature (27-31°C) and pH (6-9). This kind of system is considered effective for small-scale tilapia farming in limited areas with proper management.
