Abstract: In the present work, the efficacy of anaesthetising agent viz. Clove oil on Channa punctatus has been investigated. Experimental protocol was based on analysis of induction and recovery time with different concentrations of above anaesthetic to determine their optimum concentration. Histological studies were carried out to assess the stress induced changes caused by the application of different concentrations of clove oil. Well acclimatized fishes, divided into three groups, were exposed to three different concentrations (50, 100, 200µl/L) of anaesthetic and the changes in the above parameters were recorded. Based on the results, it is concluded that clove oil at concentration of 100µl/L is the most suitable anaesthetizing concentration due to its quick induction of anaesthetization and longer recovery time with the least stress as evident from the histological architecture of gills and buccal epithelium of C. punctatus.
