Coral nurseries are specialized facilities designed to grow and restore coral reefs. They cultivate coral fragments in a controlled environment, allowing them to develop and thrive before being transplanted back into the ocean. This process helps to combat the decline of coral reefs caused by factors like climate change, pollution, and overfishing. In these nurseries, scientists and conservationists often use techniques such as fragmentation and sexual reproduction to increase coral populations. By nurturing corals in a safe setting, they can enhance biodiversity and support the overall health of marine ecosystems, ultimately benefiting species that rely on coral reefs for habitat.
