Abstract In spite of the exuberance of recent approaches to age determination of fish, many ecologists are convinced that the most valid method is age reading from permanent marks or growth rings laid on skeletal parts. Of the known structures used, only the vertebrae are suitable and readable for a large variety of species and sizes. Examination of different skeletal structures of Labeo horie, a Cyprinid collected from Jebel Aulia reservoir, revealed that the frontal bone carried well-defined growth rings. The validity of these rings was checked against other direct and indirect methods of age determination. Results proved to be statistically valid, and the frontal bone offers an additional device of age determination of L. horie.
