The role of clove (Sygnium aromaticum) oil as anaesthetics compound for abalone (Haliotis squamata)

Abalone is one of aquaculture commodity that has a high value including in Indonesia due to its price, taste and nutrition content. Unfortunately there is problem in abalone’s transportation process which caused stress and even death. Clove oil can be used as anesthetic agent for abalone to obtain a high survival rate because of its eugenol content. This research tried to evaluate the the effect of clove oil as anesthesia agent to determined induction time, survival rate and oxygen cosumption in H squamata. This study used an experimental method and used a completely randomized design with treatment concentration of clove oil solution were 0.5 ml/L (A), 0.7 ml/L (B), 0.9 ml/L (C), and 1.1 ml/L (D) which each treatment was repeated three times, and calculated the value of the abalone (H. Squamata) survival rate after maintenance for 14 days. The results of the study showed that the survival rate of abalone seeds obtained in the treatment with the concentration of 1.1 ml/L (D). In the treatment also showed the fastest induction time with 96.67 seconds. The lowest oxygen comsumption rate in this study was treatment D with concentration of 1,1 ml/L. It could be concluded that using clove oil with concentration of 1.1 ml/L as anasthesic compound for abalone showed effectiveness in induction time, survival rate, and oxygen consumption rate.
