This research aimed to compare the stunning time and recovery time of reef ﬁsh Zebra Jakarta. Sianida and clove oil was used as anaesthetic agent in this experiment. Both substances used concentration of 5 ppm. 5 ﬁsh was used in each concentration. Fish was exposed to each concentration one by one and once ﬁsh undergo in total loss of equilibrium, time was recorded. Fish then tranferred to recovery tank contained fresh aerated sea water. Once ﬁsh recovered, time was recorded. Result shows that ﬁsh exposed to clove oil 5 ppm have faster stunning time than ﬁsh exposed to cyanide 5 ppm. However, ﬁsh exposed to cyanide 5 ppm have faster recovery time compared to ﬁsh exposed to clove oil 5 ppm.
