Title

Transplantation tests of precious coral fragments using small-sized artificial substratum

Abstract

Since the Roman era, precious corals have been used to make ornamentsworldwide, and their demand has recently increased. As a basic studyfor artificial cultivation, we transplanted Corallium japonicumfragments. In 2016 and 2017, 132 fragments approximately 3–5 cm inlength were attached to small-sized artificial substratums using marineepoxy on land. These artificial substratums, acting as transplantsubstrates, were then transported and sunk to a depth approximately 100m off the coast of Otsuki Town and Tosashimizu City, Kochi Prefecture,where precious corals once flourished. From six months to three yearspost-submersion, we successfully recovered the transplanted substratesand found a total of 107 fragments (81%). We confirmed that 106 ofthese fragments were alive 177 to 936 days after transplantation.Although we could not measure growth rates due to the initial damagecaused by the transplantation, we observed growth of coenenchymetissues, new polyps and new branches in the 104 surviving fragments.This result suggests there is great potential to artificially multiplyprecious corals, which could aid in the development of a sustainableprecious coral industry.
