Heart rate, ECG and respiratory parameters were measured with carp of about 600g during various stages of anesthesia induced with 400-800 ppm solution of 2-Phenoxyethanol. In 400 ppm solution, deep sedation, tachycardia, shortening of QT1, increase in ventialtion frequency and slight decrease in oxygen consumption were observed. In 600 ppm solution, disappearance oftachycardia, extension of time elements of ECG, decrease in all respiratory parameters were observed. In anesthesia induced with 400-600 ppm solution, fish recovered from anesthesia by irrigation with fresh water containing no anesthetic. In 800 ppm solution, progressive bradycardia, remarkable extension of time elements of ECG and decrease in voltage elements of ECG, drops to almost zero in respiratory parameters owing to cessation of ventilation movement were observed and fish did not recover from anesthesia by irrigation with fresh water. Decease of fish caused by 2-Phenoxyethanol of 800 ppm was considered to be owing to anoxia induced by paralysis of the respiratory center.
