Increasing rates and scales of disturbances are reducing reef-building coral cover and community function on many reef systems globally, decimating adult breeding populations and reducing larval supply and settlement processes that are essential for reef recovery. Coral restoration using sexual production of millions of genetically diverse coral larvae can aid restoration of coral populations and communities on damaged reefs. However, scaling up of larval production and increasing the efficiency of larval supply to enhance settlement and recruitment outcomes are issues needing further research. This presentation focuses on recent novel reef-based research to increase the scale and success of mass larval production using wild spawn slicks in floating larval culture pools on reefs, and innovative approaches to enhancing larval settlement rates, and coral growth and survivorship for restoration of damaged reef sites. Future plans for increasing mass larval production and recruitment outcomes for larger scale restoration trials will also be presented.
