Abstract: In this study, the efficacy of three anaesthetic agents (Clove oil, 2-phenoxyethanol and benzocaine) was compared in captive-bred Himri barbel, Carasobarbus luteus (Heckel, 1843). The lowest effective concentrations based on the efficacy criteria of complete anesthesia induction within 180 sec and recovery within 300 sec were determined to be 75 mg L-1 (induction 143±15 sec and recovery time 149±35 sec) for clove oil, 500 μL L-1 (induction 145±27 sec and recovery time 57±16 sec) for 2-phenooxyethanol and 50 mg L-1 (induction 152±49 sec and recovery time 88±24 sec) for benzocaine. The onset of individual phases of anesthesia and recovery times depended significantly on the concentration of the anaesthetic used (p<0.05). An inverse exponential relationship was observed between concentrations of anaesthetic and induction time whereas exponential relationships were observed between concentrations and recovery times for all anaesthetic agents evaluated.
