Abstract: The anesthetic effects of clove powder were studied in juvenile Roach, Rutilus rutilus. The effects of exposures to various dosages of clove powder were measured.Times to induction and recovery from anesthesia were measured. The times to achieve anesthesia exhibited a negative exponential response to dose. The hematological parameters was assessed before, immediately after 7 min of anesthesia and 24 h, after the anesthesia at the concentrations of 175, 225, 275 and 350 mg L¯1 clove powder. The 7-min exposure to clove powder caused the significant increase (p<0.05) in the hematocrit, hemoglobin and total erythrocyte count after anesthesia .These values returned back to normal within 24 h .Clove powder anesthesia had not effect on other hematological parameters. Results of the examinations suggest that the use of clove powder at the concentrations of 175, 225, 275 and 350 mg L¯1 does not cause irreversible damage of the blood parameters in Roach.
