abstract::The trace element composition of the fish otolith is an indicator of biomineralization. In contrast to other skeletal tissue, the otolith retains its entire original structure and does not absorb any elements after the fish dies. Because otoliths in carp degrade very slowly in the dead body, the information it provide...
