Abstract :
The use of anaesthetic agents may reduce stress-induced damage to the fish. In the current investigation, anaesthetic efficacy of 2-phenoxyethanol (500 μL.L^-1, 600 μL.^-1, 700 μL.L^-1 and 800 μL.L^-1) on Etroplus suratensis (Bloch 1790) was evaluated. 2-phenoxyethanol appears to be a highly effective anaesthetic in fishes. The time periods necessary for the induction of particular characteristic stages of induction and recovery were determined.The results showed that 600 μL.L^-1 was the effective concentration that induces anaesthesia in E. suratensis (induction in 171±13 sec and recovery time 149±21 sec; p 0.05). An exponential relationship was observed between concentrations and recovery time, whereas an inverse exponential relationship was observed between concentrations of anaesthetic and induction time
