Enhancement of coral recruitment by in situ mass culture of coral larvae

Abstract: New technologies for culturing and settling scleractinian coral larvae in the field are required to elucidate the role of recruitment in population dynamics and to provide options for reef rehabilitation. Natural multi-species aggregations of coral embryos, which frequently form slicks on the sea surface after large-scale annual spawnings, were identified as a potential resource for mass coral culture. Slicks containing billions of embryos were found at sea and several million embryos were sub-sampled and succ… Show more

“…The results presented here demonstrate that complex microbial biofilms more than 2 weeks old are able to induce metamorphosis both in the presence and absence of CCA and highlight the potential for biofilms to influence coral recruitment patterns following mass spawning events. These findings may be applied to enhance the artificial rehabilitation of reefs degraded by natural climatic phenomena, crown-of-thorns starfish, or coral bleaching (14). Timely mechanical preparation of the seabed and subsequent development of appropriate microbial biofilms, prior to predictable mass spawning events, may enhance coral recruitment.…”

“…Mesh enclosures may be used for seeding in the sea. A technique that combined floating larval rearing ponds with direct seeding has been tried in Western Australia and Okinawa (Heyward et al 2002;. The results have shown that early recruitment can be significantly enhanced; however, the majority of these settled corals died due to natural processes.…”

“…Mass spawnings frequently produce slicks on the sea surface that contain billions of embryos. Millions of embryos from slicks have been confined and successfully maintained in floating ponds until competent to settle (Heyward et al 2002). Another source, perhaps more suitable for small areas, is coral farms that now produce a large variety of species that are intended for transplantation (Borneman and Lowrie 2001).…”
