There is debate in the literature as to whether scales of fishes require acidification to remove inorganic carbonates prior to stable isotope analysis. Acid-treated and untreated scales from 208 Atlantic salmon from nine locations on both sides of the Atlantic were analysed for δ<sup>13</sup>C and δ<sup>15</sup>N. Linear mixed-effect models determined the effect of acid treatment to be statistically significant. However, the mean difference was small (δ<sup>13</sup>C 0.1 ± 0.2‰, δ<sup>15</sup>N ...[more]
