Corals mass-cultured from eggs and transplanted as juveniles to their native, remote coral reef.

The article presents a study which developed practical techniques for the rehabilitation of coral reef through the production of juveniles that are taken from sexual reproduction for a remote island with limited recruitment. The study was conducted by researchers where the adult corals of Acropora tenuis were taken from Okinotorishima, Japan to a hatchery on Okinawa and were maintained in land tanks. The substrates were transplanted in three experimental treatments to be able to examine the effectiveness of protection by cages and/or hiding the juvenile corals. It was found out that the cages protected the corals from predation and eating by other fishes.
