Half‐length (0.5‐mm‐long) coded wire tags were implanted in the snouts of juvenile chum salmon Oncorhynchus keta (1,500 fish/kg). Histological examination revealed substantial damage to one of the main‐stem olfactory nerves in 18 of 44 fish. Such damage should be of particular concern because of the well‐documented role olfaction plays in salmonid behavior.
