| Abstract: | As Lewis et al . reported in J. Fish Biol. 26 , 355–358 (1985) that the anaesthetic tricaine methanosulphate (MS 222) damaged the olfactory epithelium of channel catfish, two assays were used to determine whether MS 222 or 2-phenoxyethanol (an alternative anaesthetic) influenced subsequent olfaction-mediated behaviour. Tests revealed that the homing of adult chinook salmon, Oncorhynchus tshawytscha , and the l-serine avoidance response of juvenile coho salmon, O. kisutch , were not altered by anaesthesia. |
