AbstractSince 2004, the Monterey Bay Aquarium, California, has displayed six juvenile white sharks, Carcharodon carcharias (Linnaeus, 1758), in the 3,800 m3 Outer Bay exhibit. Upon capture, the sharks (132 - 164 cm total length (TL) and 19.6 - 47.0 kg body mass (BM)) were held in a 13,800 m3 ocean pen to initiate feeding prior to transport. Oxygen consumption rates of free-swimming C. carcharias during transports were analyzed, yielding one of the highest reported mass-specific muscle oxygen consumptions (MO2) for any shark species (246 ± 13 mg O2/kg/h). While on display (70 - 198 days), four of the C. carcharias fed consistently at a daily ration of 747 ± 46 g, or 1.62 ± 0.15% BM/day. One shark did not feed and was released after 11 days; another shark fed intermittently and was released after 55 days, but died immediately post-release. Mean mass growth rate for C. carcharias at the Monterey Bay Aquarium was 71.6 ± 8.2 kg/yr, with a corresponding mean dietary gross conversion efficiency of 27.1 ± 3.8%. The mean length growth rate (64.9 ± 8.5 cm/yr), was approximately twice the rate estimated from a published von Bertalanffy growth function. All C. carcharias were fitted with pop-up archival satellite tags upon release, which provided evidence of post-release survivorship.
