Change of δ¹³C with time after diet switch in muscle of (a) individual and (b) grouped captive California yellowtail Seriola dorsalis. (a) Points represent individual δ¹³C measurements and lines show associated model fits, colored by individual. Values t_1/2 is the half-life of ¹³C for each individual and r² values are shown for model fit to each individual. Data shown only for yellowtail that were in captive conditions for enough time to reach steady-state with new diet. (b) Model fit (solid line) and 95% confidence bounds (dashed lines) for all yellowtail sampled. Grouped data includes fish that were removed from captivity or suffered mortality during the experimental period.
