PICRC Concludes Coral Spawning Training to Strengthen Reef Restoration Capacity

The Palau International Coral Reef Center (PICRC) has successfully completed an intensive two-month coral spawning training program held from March to April 2025. The initiative aimed to build local and regional expertise in coral reef restoration, addressing the urgent need for climate-resilient solutions.

Led by Dr. Adriana Humanes, a leading expert in coral reproduction, the training brought together participants from diverse backgrounds with a shared commitment to marine conservation. “I was incredibly impressed by their dedication and curiosity,” said Dr. Humanes. “They engaged deeply in both the theory and hands-on components, showing real potential to lead future restoration efforts.”

Over the two months, participants gained practical skills in coral spawning techniques, including handling delicate coral colonies, gamete collection, water quality control, and maintaining the viability of coral eggs and sperm. A key component of the training was the use of coral from PICRC’s established seven-year-old nursery, giving participants firsthand experience with long-term restoration infrastructure.

In addition to practical training, the program covered advanced topics such as genetic diversity and its role in coral resilience. Participants explored how selecting genetically distinct parent colonies and performing controlled crosses could help corals better adapt to stressors like rising sea temperatures.

“This program is a significant step forward in building the local capacity needed to safeguard our reefs,” said Ms. Roxanne Siual Blesam, PICRC CEO. “By investing in the next generation of coral restoration practitioners, we are ensuring that Palau and the region are better equipped to face the impacts of climate change with sustainable, science-based solutions.”

The training instilled a deep sense of purpose and motivation in participants. “It’s so important for us, as Palauans, to be at the forefront of protecting our own natural heritage, “said Ms. Mengiau Sasao, a Junior Researcher with PICRC’s Outreach Department. “This training has equipped us with the knowledge and skills to lead coral restoration efforts and ensure the long-term health of our reefs.”

Dr. Humanes sees this cohort as an essential part of PICRC’s restoration efforts going forward. “Several participants demonstrated strong leadership potential,” she noted. “We’re excited to support their continued growth in monitoring, lab-based spawning, larval rearing, and reef restoration projects.”

This training reflects PICRC’s commitment to building local capacity and advancing coral conservation through science, education, and collaboration. PICRC extends its deep appreciation to The Nature Conservancy and Newcastle University for their vital partnership in making this training a success.
