Isotopic Differences between the Left and Right Side Otoliths of Flatfish Indicating Growth rather than Environment

The isotopic differences between the left and right sagittal otoliths of Pacific halibut  Hippoglossus  stenolepis, a flatfish with both eyes on the right side. Using microsampling techniques we were able to collect subsamples from the nucleus and the 5th and 8th annulus from 63 pairs of halibut otoliths. Isotopic analyses of δ13C and δ13C showed that there was a significant difference between the left and right side otoliths from the nucleus in both Washington Coast and Puget Sound samples; but no significant difference from the 5th and 8th annuli of the same otoliths.
