Abstract

Abstract. A simple technique of grinding eel otoliths (sagittae) for age/growth studies is described. On thin, polished otolith layers the annual growth rings, as well as supernumerary zones formed in fresh water, could be easily distinguished. The described equipment and grinding procedure gave good results on permanent preparations, allowing repeated age‐readings. The procedure appears to be applicable to other fish species as well.
