Sammendrag

This study re-evaluates the current ageing methodology for the Atlantic halibut, Hippoglossus hippoglossus. The traditional method is through surface readings of otoliths, but, based on new experiments with different preparation treatments and techniques, a more accurate and cost-efficient procedure for the age determination of Atlantic halibut is proposed.
