87Sr/86Sr isotope ratio analysis by laser ablation MC-ICP-MS in scales, spines, and fin rays as a nonlethal alternative to otoliths for reconstructing fish life history
Malte Willmes, Justin J. G. Glessner, Scott A. Carleton, Paul C. Gerrity, James A. Hobbs
2016, Canadian Journal of Fisheries and Aquatic Sciences (73) 1852-1860
Strontium isotope ratios (87Sr/86Sr) in otoliths are a well-established tool to determine origins and movement patterns of fish. However, otolith extraction requires sacrificing fish, and when working with protected or endangered species, the use of nonlethal samples such as scales, spines, and fin rays is preferred. Unlike otoliths that are...
