Comparisons between the stable isotope composition of carbon in collagen excized from juvenile (freshwater) and adult (marine) portions of scales from Atlantic salmon Salmo salar demonstrated that c. 75% of carbon analysed in the ‘juvenile’ portion of the scale derives from later formed collagen. Scale collagen analyses were effectively restricted to the last season of growth.
