Comparisons between tissues, preservation, and desiccation methods on stable isotopes Delta13C and Delta15N of spot-tail sharks (Carcharhinus sorrah) from the South China Sea
This study presents the δ13C and δ15N values of spot-tail sharks (Carcharhinus sorrah), focuses on the inter-tissue comparisons between fin and muscle tissues; the effects of ethanol preservation as compared with freezing and evaluations of oven- and freezedrying desiccation methods. The average δ13C and δ15N values significantly differed between fin and muscle tissues and were correlated for selected treatments. Ethanol preservation did not affect δ13C but significantly enriched δ15N in the muscles, whereas both desiccation methods produced similar results. Freezing samples for preservation is recommended for stable isotope analysis, whereas desiccation methods can be chosen at the researchers’ discretion.
