Stable isotope analysis of tissue samples to investigate trophic linkages of Antarctic toothfish (Dissostichus mawsoni) in the Ross and Amundsen Sea regions
Abstract: Stable isotopes of carbon and nitrogen (δ 15 N and δ 13 C) in Antarctic toothfish ... in muscle on δ 13 C in a way that did not compromise the accuracy of δ 15 N measurements. We found ... considerable variability in δ 15 N and δ 13 C of toothfish that were not explained by fish length, sex ... , location, depth or year of capture. We found statistically significant but small relationships between δ 15 ...
