Handlings and transport of fish are the most stressful procedures in aquaculture. The anesthetic efficacy of two types of natural anesthetics in both forms of powder and oil were evaluated on young common carp (Cyprinus carpio L.) with the mean weight of 60±10g for handling and health management experiments. These works were conducted in the laboratory of fish research in the Department of Animal production, Faculty of Agricultural Sciences at University of Sulaimani. The study included three experiments. In the first experiment, safety concentrations of anesthetics type and concentration were assessed by using two types of clove and mustard anesthetics in both forms of powder and oil; each with three replicates for measuring induction times to anesthesia. The induction time of C. carpio which decreased with increasing concentrations of clove powder, the induction time was less than three minutes for a dose of 400mg/L, which was 137.11 sec. was significantly different (P<0.05) from the other dosages (200 and 300 mg/L). As the concentrations of clove powder increased the ventilation rate in stage I, II and III of anesthesia and recovery increased significantly (P<0.05) compared to the control.
