Common carp, Cyprinus carpio L. is a commercial aquaculture species and also a pest fish that can destroy local aquatic communities. An effective anaesthetic method has been developed to meet both aquacultural and ecological studies of the fish. Clove oil is a cheap and safe anaesthetic for fish and humans. However, there are few reports on its efficiency on adult carps. In this study, using carp samples (average wet weight = 1.25 kg), effective concentrations of clove oil was determined by to be 50 mg L-1. The induction time taken to reach each of anaesthetic stages appeared to be inversely proportional to clove oil concentration.
