Abstract

In this research, the anesthetic effects of peppermint essential oil with concentrations of 100, 150, 200, 250 and 300 mg/l and its comparison with concentrations of 20, 30, 40, 60, 80 and 100 mg/l of essential oil Clove was evaluated in rainbow trout. 132 fish with an average weight of 23.31±1.27 grams were used for anesthesia experiments. The induction time of anesthesia using peppermint essential oil varied from 1.69 to 4.81 minutes among different concentrations. In the case of clove essential oil, this time varied from 0.82 to 2.51 minutes in different concentrations. Recovery from complete anesthesia in both anesthetics significantly decreased with increasing concentration of the anesthetic. The recovery time from complete anesthesia in the case of peppermint essential oil was from 2.50 to 5.55 minutes and in fish anesthetized with essential oil. Clove varied from 2.96 to 3.87. Based on the ideal criteria of induction of anesthesia (less than 3 minutes) and recovery from anesthesia (less than 5 minutes), the most suitable concentration of peppermint essential oil to anesthetize salmon in the tested weight is 200 mg/l and the most suitable concentration of essential oil Cloves are also recommended at 30 mg/l
