Elemental analysis of otoliths, fin rays and scales: a comparison of bony structures to provide population and life‐history information for the Arctic grayling ( Thymallus arcticus)
Abstract – We used laser ablation inductively coupled plasma mass spectrometry line scans to determine the elemental composition of otoliths, pectoral fin rays and scales of Arctic grayling. Elemental signatures of otoliths and pectoral fin rays effectively provide life‐history information on indivi...
