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 non-lethal samples such as scales, spines, and fin rays, is preferred. Unlike otoliths that are predominantly aragonite, these tissues are comprised…
