Abstract

Abstract

Sexual reproduction of hermatypic corals for coral reef restoration has become a hot topic in recent years. In May 2018, the samples of Favia favus and Platygyra carnosus were collected from the water of Weizhou Island, Guangxi. All of them were cultured in laboratory and the fertilized eggs were collected. The early development process of embryos and larvae was observed and recorded. The results showed that F.favus and P.carnosus were both hermaphrodites, in vitro fertilization, and began to spawn on the fifth to eighth day after the full moon; the early development of embryos and larvae experienced the cleavage stage, blastula stage, gastrula stage and planula stage; the oocytes of two corals did not have zooxanthella as they were ejected. This study records the sexual reproduction behavior of reef-building corals in Weizhou Island, and provides a theory when using sexual reproduction for coral ecological restoration in the future.
