In this study, the reproduction biology of 172 Prussian carp (Carassius gibelio (Bloch, 1782)) was studied from June
1999 to June 2000 monthly in Topçam Dam Lake. The sex and age composition of Prussian carp were determined.
Individuals were composed of 1.16% males and 98.84% females. In this study, fully mature specimens were defined as those
which were ready to reproduce at the third age. The spawning of Prussian carp took place between March and August, and
suggesting that it is a multiple spawner. The mean fecundity of Prussian carp varies from 37,823 (August) – 85,159 (March)
for female monthly. The average egg diameter was between 0.533 (January) – 1.099 (June) mm in months.
