Abstract Summary
Global deterioration of coral reefs globally due to a variety of variables has put this critical ocean ecosystem at risk. To combat this decline large-scale global action and restoration methods are being implemented. In this study, we attempt to rehabilitate coral reefs surrounding the Dutch Caribbean island, Saba, by successfully cultivating Acropora cervicornis and Acropora palmata fragments in a mid-water floating nursery. By collecting storm-generated coral fragments scavenged from the sea floor or rescued from island development projects, we attempt to mirror the asexual fragmentation process that the Acropora species naturally performs. The coral fragments hang from floating tree and ladder-like structures which can be raised and lowered to adjust for temperature fluctuation while also providing protection from sediment coverage. The position of the structures allows multiple divers ample workspace for cleaning, maintaining, and data collection in the nursery. Over a three-year period, the nursery saw encouraging signs of growth and low mortality rates. We estimate if transplantation continues successfully, implementation of floating coral nurseries in Caribbean waters could have a lasting impact on reef rehabilitation and ocean health.
