The mineralised component contains a minor inorganic carbonate component, but acid pre-treatment of scales results in biologically insignificant changes in the bulk isotopic composition56. δ13C values in the collagen component of fish scales are consistently enriched in δ13C relative to muscle values reflecting the high proportion of glycine in collagen57. Scale δ13C values are, however, linearly related to the isotopic composition of other body tissues across multiple genera, under differing diet conditions and growth rates565859, indicating a consistent relationship between scale collagen and diet δ13C values.","tracks":[]}
