Schematic showing experimental design to quantify dynamics of δ15N and δ13C in captive California yellowtail Seriola dorsalis. Sizes (cm) below x-axis show approximate changes in yellowtail fork length during the phases of the experiment. Lines showing changes in yellowtail muscle δ15N (solid line) and δ13C (dashed line) are theoretical changes based on typical isotopic turnover dynamics in teleosts.
