In this study, the reproduction biology of 332 chub (Leuciscus cephalus L. 1758) was studied from June, 1999, to June, 2000, on a monthly basis in Topçam Dam Lake. Egg numbers were estimated in 65 females caught just prior to spawning. The sex and age compositions of chub were determined. The specimens were composed of 27.11% males and 72.89% females. Male and female chub become sexually mature in the second year of their life spans. Spawning is in March and April. The fecundity of chub varies from 2100-66,400 per female. The average egg diameter was between 0.391 and 0.744 mm in various age groups.
