Using Eye
Lens Diameter as Age Indicator of Young Lithognathus
mormyrus and Diplodus vulgaris

Abstract
Eye lens diameter was analyzed in two sparid fish
species, Lithognathus mormyrus and Diplodus vulgaris,
in order to determine the possibility of using
these data for age determination. The results
showed that the technique could be adopted for
determining the age of the two species when the
specimens are very young. The method is especially
useful for age determination when otolith or scale
rings are not visible or when false rings may
give erroneous readings.
