Abstract :

       Powder cloves is preparing of flowers and dry stalks cloves tree and  used for an anesthesia fish in the short term.it is water-soluble and easily accessible with low cost. The anesthetic effects of clove powder were studied in juvenile rainbow trout (Oncorhynchus mykiss). The effects of exposures to various dosages of clove powder were measured. Times to induction and recovery from anesthesia were measured. It was used in concentrations of 50, 100, 150 and 200 mg/L clove powder  and The hematological parameters was assessed before, immediately after 5 min of anesthesia and 24 h, after the anesthesia. Result indicated that time to reach various stages of anesthesia and recovery time of consciousness is directly correlates with the concentration of anesthetic solution.. Blood samples 5 min exposure 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 hours .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 50, 100, 150 and 200 mg/L does not cause irreversible damage of the blood parameters in rainbow trout.
