Gonadal development is a crucial process for sexual reproduction in scleractinian corals, after the gonad matured, corals will spawn in suitable environments, understanding this process is essential for predicting their spawn time. However, there is no report on the gonadal development cycle and the spawning time of corals in Weizhou Island is currently unknown. From September 2021 to May 2022, our study focused on Acropora formosa and Favites abdita in Weizhou Island to observe their gonadal development process and spawning time. In the wild, the oocytes of A. formosa began to develop in September and matured after nine months, while the testes were observed in November and matured after two to three months. In F. abdita, the onset of oocytes was between in October and November, mature oocytes were observed after seven to eight months, with the development period of the testes was about one to two months. Both corals’ gametes matured in May. In tanks, both corals were observed to spawn between May 19 to 22, 2022 ( April 19 to 22, Chinese lunar calendar), which was consistent with their spawning observed in wild. Based on the results, we postulate that the spawning time of A. formosa and F. abdita in Weizhou Island is around April 15th, Chinese lunar calendar. This study provides valuable information on the reproductive biology of Weizhou Island corals.
