Here, we estimate AUCss values for oxytetracycline (OTC) in serum of rainbow trout Oncorhynchus mykiss by using a destructive sampling study design. Seventy-two rainbow trout were fed OTC-medicated feed at 74.7 \u00b1 1.5 mg\/kg (mean \u00b1 SD) body weight (BW) by oral gavage for 10 consecutive days. Serum was collected from nine fish at 1, 3, 6, 8, 10, 12, 15, and 22 d after dosing began. Serum OTC concentrations were measured by high-performance liquid chromatography with a 0.01-\u03bcg\/mL limit of detection. The average OTC AUCss was 29.2 \u03bcg \u00d7 h\/mL and was estimated using nonlinear mixed-effects modeling and bootstrap resampling techniques. The elimination half-life was estimated as 85.0 h, and the fraction of steady state achieved was estimated as 0.85. The calculated AUCss (24.8 \u03bcg \u00d7 h\/mL) following 10 d of oral dosing with 75 mg OTC\/kg BW was less than the estimated AUCss. Results suggest that the pharmacokinetics of OTC exposure, including the AUCss, is better evaluated by using multiday dosimetry than by using a standard single-dose protocol.<\/jats:p>\n
