Success of coral reef restoration through sexual spawning at Egyption red sea

Title : Success of coral reef restoration through sexual spawning at Egyption red sea

Abstract:

Sexual reproduction of corals is one of the key processes for the stability and reproduction of coral reefs. According to the literature and our survey , mass spawning of Acroporidae  in red sea actually matures in late April, and all are empty in early May. We documented the slicks of maturing eggs during 2017, 2022, 2023 and 2024  through mass picncky coloure which indicate the spawning of coral in sea were set , Spawning slicks indicate that many of these colonies released gametes in April-May each year. We have witnessed the accumulation of pink slicks of coral eggs in different years 2017, 2022, 2023 and 2024. We can collect and receiving fertilized eggs which are examined under a microscope for use in coral restoration. The slicks collected from that accumulate on the surface and placed in an artificial tank closer to the sea, after 6 months of set slicks  recruitment of ten individual Acropora corals were grown in the tank.
