Investigation of migration and provenance of eel using multielement and Sr – isotope pattern.
Abstract
Eels are an endangered species of which the migration behaviour is only little understood. In this research project, analysis of eel otoliths and eel soft tissues by means of (LA)-ICP-SFMS and (LA)-MC ICP-MS for elemental (Li, Ba, Mg, B, Fe, Zn, Sr, Ca, Mn, Zr, Pb, U, S) and 87Sr/86Sr isotope analysis. Eel of different provenance will be provided. A special focus is set on glass-eel, representing the juvenile status of the fish. Since the samples are extremely challenging, existing analytical protocols will be further developed and optimized for the respective research question. The to be developed database will be compared with water data in order to reconstruct migration and provenance of the investigated fish samples.
