The aim of this study was to establish the sex ratio, age of sexual maturity, spawning period and fecundity of common carps (Cyprinus carpio) in Almus Dam Lake from October 2002 to September 2003. The overall male to female ratio was 1:1.4. Females and males began to be mature at the age of 4 and 3. All of them were mature at the age of 5 and 4, respectively. Fork lengths at maturation were 22.88 and 27.48 cm for male and female, respectively. Maximum ages observed were 4 in males and 7 in females. Reproductive period started in June for males and July for females and continued until the beginning of August. Individual fecundity of the females was found between 2405-107089 for the population.
