Abstract

The morphological features of the saccular otoliths of Tilapia guineensis are given. Procedure for treating the otoliths for observation of growth rings is described. Growth rings observed on the otoliths are interpreted as being either daily growth markings, or weekly marks. The distribution of the growth marks is used in estimating the age of the fish.
