چکیده

Sable®sh (Anoplopoma ®mbria) were recaptured up to 20 years after being injected with oxytetracycline (OTC). After 20 years the OTC mark is clear in most otoliths. Our examination of these otoliths con®rmed that sable®sh are long-lived and grow slowly after maturity. Annuli that formed beyond the OTC mark could be dif®cult to interpret in broken and burnt sections. However, polished thin sections improved the clarity of annuli. Despite improved preparations, annuli in some sections were dif®cult to distinguish, resulting in annuli counts after the OTC mark that did not correspond exactly to the years at liberty of the recaptured ®sh. # 2000 Elsevier Science B.V.
