Acute Toxicity and Optimal Dose of Clove Oil as Anaesthetic for Blue Hill Trout Barilius bakeri (Day)
(Society of Fisheries Technologists (India)Cochin, 2013) Sindhu, M.C; Ramachandran, A
Stone (1999) and Kildea et al. (2004) have assessed the advantages and disadvantages of clove oil as a fish anaesthetic. Most of them have reported it to be safe and effective anaesthetic but it has a narrow margin of safety. Care must be taken when using high concentrations of clove oil for induction, because ventilatory failure may occur rapidly. A combined view of the findings leads to the recommendation that, for the size of blue hill trout used in the present study, clove oil, with fast induction and rapid recovery times offers a manageable, safe anaesthetic alternative, which can be useful in aquaculture and fish handling activities. In future clove oil would be in use as an anaesthetic in Indian blue hill trout for long distant transportation.
