| Abstract |
|
Seasonal variation in the reproductive cycle of female Chinese three-keeled pond turtles, Chinemys reevesii, was studied. Vitellogenesis began in early October and reached maximum level in early May (maximum follicle diameter was 19.2 mm). The first clutch was laid in June. Oviposition continued until August when follicular regression began. An ovarian quiescent period was evident in September. Two-three clutches are laid per year. Mean clutch size is 5. Annual reproductive potential ranges from 10 to 15 eggs. Age at maturity for females is six years.
