| Abstract |
Oxytetracycline (OTC) was intraperitoneally injected into pike, Esox lucius L., to determine the validity of ages derived from cleithra and pelvic fin rays, to determine the rate of OTC incorporation into calcified structures, to decermine suitable marking dosages and to assess OTC‐induced mortality. The results showed that annuli were laid down on pike cleithra and pelvic fin rays. OTC was incorporated into most calcified structures as early as 6 h after injection and all structures were marked within 24 h. A dosage range of 25–50 mg OTC/kg fish was appropriate for marking pike. OTC‐induced mortality was statistically insignificant. |
