Annulus Formation in Tigris-nase (Chondrostoma regium (Heckel, 1843))
In this study, scales from Tigris-nase (Chondrostoma regium, (Heckel,1843)) inhabiting the Suat Uğurlu Dam were studied and the ages were determined. Time of annulus formation was derived from annual changes of opaque and hyaline zones on scale margins. It was concluded that new (scale annuli in the) Tigris-nase begin to form in October and are completed in February.
