The objective of the study was to evaluate the anaesthetic effects of Propiscin (2% etomidate) and 2‐phenoxyethanol on common carp ( Cyprinus carpio L.) by observing neural and behavioural measures. When exposed to the anaesthetic agent, the carp lost equilibrium after approximately 90 s of exposure. They did not breathe and the controls did not respond to tail pinch or prick or 6 V at the skin of the upper jaw. A shift to lower frequencies on the electroencephalogram (EEG) and computing fast Fourier transformation was observed when exposed to water containing Propiscin or 2‐phenoxyethanol. Heart rate was reduced after placement in the water containing an anaesthetic agent. It may be concluded from our results that common carp were immobilized and sedated, when exposed to water containing 2 mL L −1 Propiscin and immobilized and anaesthetized in water containing 0.5 mL L −1 2‐phenoxyethanol. In addition, the use of EEG provides for a sound assessment of exposure of carp to these anaesthetics.
