The otolith calcium carbonate polymorph composition was determined using Raman spectroscopy. Raman spectra were recorded from 5 round and 5 irregular otoliths with a Horiba Jobin Yvon LabRam HR instrument using 514 nm excitation and a 50× magnification long-working distance objective. Laser intensity was attenuated using neutral density filters to ensure that laser-induced transformation of the polymorph was not occurring. Spectra were recorded from the centre of the otoliths. Aragonite, calcite and vaterite minerals (kindly provided by Dr Nicola Allison, School of Earth and Environmental Sciences, University of St Andrews) were also recorded as standards to correctly identify the CaCO3 polymorph present in the larval otoliths.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
