摘要

As global reef degradation continues, researchers and managers are increasingly adopting active restoration and ecological engineering approaches to mitigate coral loss and support recovery. One of the most widely used coral restoration methods is “coral gardening”, which involves collecting small coral fragments, cultivating them in mid-water floating nurseries, and later transplanting them onto degraded reefs. Over time, floating coral nurseries have evolved beyond their original purpose of coral propagation, now serving as innovative tools to mitigate climate change impacts on reefs. This shift has led to the development of "Forethoughtful Coral Nursery" (FCN), each designed with specific objectives beyond coral transplantation. Five distinct FCN types have been identified: (1) Assisted Genetics – transforming traditional mid-water coral nurseries into larval dispersion hubs to seed degraded reefs with propagules; (2) Assisted Connectivity – applying the stepping-stone concept in reef restoration by establishing chain of mid-water nurseries between disconnected reefs; (3) Assisted Biodiversity – using coral nurseries as genetic repositories, preserving coral species and associated biota; (4) Carbon Sequestration Facilitation – adapting mid-water nurseries to function as CO₂ sinks, with the potential for conversion into carbon credits; and (5) Assisted Economy – utilizing nurseries for commercial purposes (e.g., the aquarium trade, bioactive compound extraction, tourism), education, and research. While some of these FCN concepts are still in the proof-of-concept stage, they hold promise as practical tools for reef management. Positioned at the intersection of ecological, societal, and economic challenges, these innovative approaches warrant further scientific exploration and integration into conservation strategies.
