In 2002, the Monterey Bay Aquarium (MBA) started a project to display young-of-the-year (YOY) White Sharks (Carcharodon carcharias) in the 3.8-million-L Outer Bay exhibit and to conduct field research on the movement patterns of this highly active predator in the Southern California Bight. A pelagic fish transport tank used to bring YOY White Sharks to the MBA between 2004 and 2009 allowed the first direct measurements of oxygen consumption rates (MO2) of free-swimming White Sharks during transport, ranging in duration between 5 and 7.5 h. We obtained MO2 data during five transports of four individual White Sharks [137-157 cm of total length (TL) and 22.6-36.2 kg of body mass] at water temperatures ranging from 15.2 to 17.9°C. The mass-specific MO2 calculated from 16 measurements for the four sharks was 246 ± 13 mg O2 kg-1 h-1 (mean ± SE), which is among the highest reported for any shark species. Total MO2 values of White Sharks from our study were pooled with the routine metabolic rate of the Shortfin Mako Shark to estimate the mass-scaling relationship for lamnid sharks, which is described by the allometric equation MR = 458.5 × M0.79.
