Data from: Estimation of lifelong metabolic rates in marine fish: A combination of oxygen consumption measurements and δ13C metabolic proxy derived from vertebral structural carbonates

Adjustments in the metabolism of marine fish are associated with the
complexity of resource availability, prey-predator relationships, and
biotic and abiotic interactions in the natural environment. To investigate
the relationship between metabolism and body mass, this study used a
conventional method to estimate the oxygen consumption rate (reflecting
the resting metabolic rate) in black porgy, Acanthopagrus schlegelii, over
a year of rearing. In addition, we developed a novel metabolic proxy using
the δ13C values of vertebral structural carbonates to monitor lifelong
metabolic changes. The oxygen consumption measurements followed a
decreasing mass-dependent trend and yielded a mass-specific allometric
exponent scaling (−0.24). By integrating the oxygen consumption with the
advanced δ13C metabolic proxy, we established a decay model in an
increasing form to describe the relationship of two measurements, and it
could be further used in wild fishes and broaden the metabolic studies in
marine vertebrates.
