Compared to the other anesthetic and sedative agents, clove oil is plant based, does not harm human and animal health, has only a few side effects, is a practical and economic agent. Clove oil is a rather strong and effective sedative and anesthetic agent even though it is used in low doses. In this study, the aim was to determine the most appropriate clove oil dose for a known sensitive aquarium fish. For this purpose; 0.5, 1, 1.5, 2, 2.5 and 3 ml/l doses of clove oil were applied on angelfish which is one of the known stressful species during transportation. Induction and recovery times were measured for each fish separately. Recovery time was longer in the clove oil than the induction time. The shortest induction time was 15 +/- 2 s at the dose of 3 ml/l. As for recovery, the shortest time was found to be 343 s (+/- 97,SD) at the dose of 2 ml/l. This dose of shortest induction and recovery times is recommended as the most appropriate amounts for an effective sedative and anesthetic agent in economic terms for aquaculture activities, such as handling, catching with net, transporting to another tank, etc.
