Rock soles Lepidopsetta bilineata in Hecate Strait, British Columbia, were tagged and injected with oxytetracycline (OTC). Otoliths from eight of nine tagged fish recaptured 2–3 years later showed fluorescing OTC marks. Both the years since application of the OTC mark and the occurrence of growth checks could be read correctly from burned cross sections of the otoliths. Estimated ages of recaptured fish were 6–11 years.
