Why are coral spawning events significant in restoration planning?

Coral spawning events are highly significant in restoration planning primarily because they provide opportunities for larval collection. During these spawning events, corals release their gametes—eggs and sperm—into the water. This process leads to the fertilization of larvae, which then settle and grow into new coral polyps. By collecting these larvae during the spawning events, restoration practitioners can boost genetic diversity and enhance the resilience of coral populations.

The timing of these spawning events can be predictable, often occurring annually, which allows restoration teams to plan effectively for the collection and subsequent cultivation efforts. Using the harvested larvae in restoration projects can help facilitate the natural recruitment of corals in areas that have been degraded or destroyed, making it a critical component of successful coral restoration initiatives.

Other options do not align with the primary goals of restoration planning. For instance, while the idea of planting non-native species might seem relevant in some ecological contexts, it generally goes against biodiversity restoration principles. Additionally, coral spawning does not typically disrupt local fish populations; rather, it can provide a food source during the spawning period.
