Abstract:The copulation and reproduction of 7 sexually matured Cuora galbinifrons (5 females and 2 males) were studied in the Yongfu county, Guilin city, Guangxi Zhuang Autonomous Region from 2017 to 2019. By observing and recording the living, mating and breeding habits of C. galbinifrons under artificial breeding conditions, and combining with literatures, the breeding and hatching methods of C. galbinifrons were optimized in this study. The results indicated that the parent C. galbinifrons were in good growth status with annual average weight growth rate of 6.37%. The copulation peak was happened from May to June and the egg laying period was from June to July. Finally, 5 fertilized eggs were obtained and 3 individuals of F1 generation were hatched. The accumulated temperature between the first and the second egg laying periods was 197 230-207 955 ℃·h, and 3 eggs were hatched. The incubation time was 118-136 days and the accumulated hatching temperature was 76 464-88 128 ℃·h. The hatching rate was 60.00%. This study provides theoretical and practical basis for further improving the artificial breeding and reproduction of C. galbinifrons.
