Abstract
This study sought to resolve whether sturgeon (Acipenseridae) sagittae (otoliths) contain a non‐vaterite fraction and to quantify how large a non‐vaterite fraction is using neutron diffraction analysis. This study found that all otoliths examined had a calcite fraction that ranged from 18 ± 6 to 36 ± 3% by mass. This calcite fraction is most probably due to biological variation during otolith formation rather than an artefact of polymorph transformation during preparation.
