KRALENDIJK – Reef Renewal Foundation Bonaire has reported a major milestone in its coral restoration efforts after more than 600,000 coral embryos were successfully created during a recent spawning event along Bonaire’s west coast.
According to the foundation, staff members and volunteers monitored five locations on Tuesday night as grooved brain coral, known scientifically as Diploria labyrinthiformis, released eggs and sperm during a brief spawning window. Gametes were collected from 20 separate coral colonies.
Back at the organization’s on-land Coral Lab, researchers conducted pilot breeding work for the first time. The effort resulted in a reported fertilization rate of 94 percent.
Grooved brain coral is considered one of Bonaire’s important reef-building coral species, but populations have suffered significant damage in recent years due to coral bleaching and stony coral tissue loss disease (SCTLD).
The organization explained that coral breeding can help reconnect fragmented coral populations by bringing sperm and eggs together that may no longer naturally meet in the ocean.
Genetic diversity
By increasing successful reproduction opportunities, Reef Renewal Foundation Bonaire hopes to strengthen genetic diversity and improve reef resilience as ocean conditions continue to change.
The foundation described the development as an encouraging start to the spawning season and indicated that further updates will follow as the young corals continue to develop.
