Abstract: | Two anaesthetics, clove oil and MS-222, were examined for their effects on the olfactory nerve response of masu salmon (Oncorhynchus masou) and rainbow trout (O. mykiss). Exposing fish to clove oil for 3 minutes at concentrations of 50 mg/L and 100 mg/L, or for 10 minutes at 50 mg/L, did not significantly reduce their olfactory response. Directly applying clove oil anaesthesia to the olfactory epithelium significantly reduced olfactory response, though olfactory response recovered to 70% and 52% of pre-treatment levels in masu salmon and rainbow trout, respectively, after 20 minutes. After a three minute exposure to unbuffered MS-222 (100 mg/ml), olfactory responsiveness continued to decline over time but no such long-term effects were observed after exposure to clove oil or buffered MS-222. Clove oil appears to be an effective and safe anaesthetic for salmonids with no long-term impact on their olfactory response, which plays a crucial role in their life history. |
