Abstract
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 the two measurements, and it could be further used in wild fishes and broaden the metabolic studies in marine vertebrates.
期刊介绍:
Limnology and Oceanography Letters (LO-Letters) serves as a platform for communicating the latest innovative and trend-setting research in the aquatic sciences. Manuscripts submitted to LO-Letters are expected to present high-impact, cutting-edge results, discoveries, or conceptual developments across all areas of limnology and oceanography, including their integration. Selection criteria for manuscripts include their broad relevance to the field, strong empirical and conceptual foundations, succinct and elegant conclusions, and potential to advance knowledge in aquatic sciences.
