Eyes and ears: A comparative approach linking the chemical composition of cod otoliths and eye lenses.

ABSTRACT: Fish eye lenses are a protein-based chronological recorder of microchemical constituents that are a potentially useful tool for interpretations of environmental, ecological and life-history experienced by fish. Here, we present the first study with data on the chemical composition of eye lenses from Baltic cod examined using laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) and compare these spatially resolved data to otoliths from the same fish also analysed by LA-ICPMS, measuring the isotopes ²⁷ Al, ¹³⁷ Ba, ⁴³ Ca, ⁵² Cr, ⁶⁵ Cu, ⁵⁷ Fe, ³⁹ K, ⁷ Li, ²⁵ Mg, ⁵⁵ Mn, ³¹ P, ²⁰⁸ Pb, ⁸⁵ Rb, ⁴⁵ Sc, ²⁹ Si, ⁸⁸
