Coral propagation is the process of growing new coral colonies from existing ones. This can be done through methods like fragmentation, where pieces of coral are broken off and placed in suitable environments to grow. Another method is sexual reproduction, where coral spawn is collected and nurtured in controlled settings until they develop into new corals. This practice is essential for restoring damaged coral reefs, which are vital ecosystems that support marine life. By enhancing coral populations, coral propagation helps improve biodiversity and resilience against threats like climate change and pollution, ensuring healthier oceans for the future.
