(IDEX Online) - With fewer than two weeks to go to the opening of the 2018 CIBJO Congress in Bogot??, Colombia, on October 15, the eighth and final CIBJO commission Special Reports has been released.
Prepared by the CIBJO Coral Commission, headed by Vincenzo Liverino, the report looks at a variety of topics related to precious coral reef sustainability, including government regulation of harvesting, research into methods for repopulating depleted areas, the use of DNA and Blockchain in achieving traceability, and online education.
"The industry encourages the enforcement of the current regulations and, as more scientific data on existing [precious coral] populations becomes available, hopes that harvesting and conservation practices be adapted so that resources are better managed, which is in the best interest of not only the ecosystem, but also the trade," writes Liverino.
The special report highlights a number of research projects currently underway in Japan and Monte Carlo, where precious coral samples are being grown under controlled conditions in the laboratory, and in certain cases then transplanted on the seabed.
At a project on Birou island, off the coast of Japan, being conducted by the Precious Coral Protection and Development Association and the Kuroshio Biological Research Foundation, 223 small Corallium japonicum branches were first grown in tanks under controlled conditions and eventually attached to reef-growing blocks positioned underwater at depths of 100 meters. "With the transplanting phase now completed, growth rates are being monitored and other data collected. An encouraging growth rate was recorded both before and after transplantation, and there is a remarkable survival rate of 99 percent," Liverino writes.
At the upcoming CIBJO Congress in Bogot??, an online course prepared by the Coral Commission will be presented. Catering to retailers selling precious coral jewelry, it covers a range of topics, including the history and cultural relevance of precious coral in many parts of the world, a layperson's review of the biology and taxonomy of coral, information about geographic occurrences, accepted trade names for each species, treatments and imitations, CITES and fishing regulations, sustainability concerns, product-care recommendations and a list of scientific references.
"It is hoped that the online course syllabus could become a model and primary reference for gemological and jewelry schools creating their own educational materials," Liverino notes. "They, too, have a primary role to play in raising the general awareness about precious coral and the sustainability of harvested gem materials within the trade."
