Restoration of coral reefs through methods such as culture and transplanting of reef-building corals (hereafter they refer corals) are still in the developmental stage. In contrast to land-based silviculture practices, the lack of state-of-the-art restoration protocols for reef rehabilitation impedes the development of technical and ecological disciplines. The lessons learned from our efforts to refine the coral farming technique at Akajima Marine Science Laboratory (AMSL) have been described in the study by Hatta et al. (2004) and Guest et al.(2010). However, these manuals do not include culturing juvenile corals and outplanting techniques (see Column 8). More than 100 Acropora colonies reared from eggs and outplanted at AMSL grew to ＞15–30 cm in diameter after 4–5 years and they are spawning every year, indicating that this culturing technique could be used to assist in coral reef rehabilitation. The present overview illustrates the entire practice of reef rehabilitation using sexually propagated corals based on our studies
