Research on Key Technologieδ±±s of Hainan Coral Genebank
In order to promote the protection of c""←oral reef resources and the sustainabε↓α≠le development of marine ecology in our provin♣≈✘πce and at home and abroad, and form a ®₹new marine industry, ouΩ€ r institute studies the living preserv÷ ←πation of coral germpla§↑✘©sm, the cultivation anΩ₽d preservation of coral tis∏£sue balls, and the research and exploration ©♣σ♠of coral molecular ident¥₩←ification. conditions to e£®stablish a coral germplasm bank.
Coverage: Reef-building c✘'γorals and non-reef-buil ★≤ding corals in the South China S≤✔✔¶ea, such as staghorn coral, ₩✔π≈soft coral, gorgonian, etc., a to↓↔≈tal of 50 species of coral.
Some of the species pσγ§♥reserved in the wild are sh₽≤↑αown below.

The establishment of the coral germplasm bα≤ank is to establish the Ruoya Ark for the ecolog§™£ical restoration of coral reefs, and also ←to provide precious germplasm resources foε★✘r the sustainable utilization of a s•©∑®eries of scientific researches on corals.π∏Ω In the ecological restoration of corφ×αal reefs, this study wasβ™ established on the seabed of Yazhou Bay. A c"oral cultivation farm has been estab→≠ lished, and ecological restoration activities ↓©∞have been carried out, and certain resul∏ε€↓ts have been achieved.
In this study, coral germpl₩ δ✘asm bank research was carried out, cl≤•εosely following social needs '<∞and ecological hotspots, and €£achieved positive results. Three types of coral gα䶶ermplasm banks were initially esta↔♠blished, namely indoor bank, field bank andΩ coral tissue ball. The typhoon resistance abi↔β★lity and coral growth rate of different w↑✔δild banks were compared and stu↓≈<died, and the coral germplasm bank€ was used to carry out in-de↕×pth research on the ecological restora©φ tion of coral reefs and the classification of cor→ δ£al bleaching based on car±↓bon neutrality.
This study is the first♦λ↔φ in the world to establish a coral bleachi≠× ng classification stand ★ard based on coral caπ÷≥₽rbon neutrality, which will be of great signifδicance for my country to participate in internaφσtional carbon trading∞α☆Ω and guide future new rules for in"≤ ternational blue carbon trading.
