In addition to common chemical preservatives ethanol and formalin, we also assessed the potential impacts of freezing on δ13C and δ15N values and compared the preserved samples against freshly dried and analysed samples. All preservation methods, including freezing, had significant impacts on δ13C and δ15N values and the effects in general were greater on the carbon isotope values (1.3-2.2‰ difference) than on the nitrogen isotope values (0.9-1.0‰ difference). However, the impacts produced by the preservation were rather consistent within each method during the whole 1 year experiment allowing these to be accounted for, if clams are intended for use in retrospective stable isotope studies.
