Ex situ conservation method of coral stone

Abstract

The invention relates to an ex-situ conservation method for scleratinia and is characterized in that after the whole polyparium is excavated from origins, small corals with the diameter less than 25cm are fixed on a transplanting board by chemotec with the curing time of 30 to 60 minutes and then is placed into a fostering box full of seawater for fostering; the fostering box is fixed on a ship and is moved to the migration destination; large corals with the diameter more than 25cm is placed into a net box in the water for fostering and the transplanting board and the large corals are placed to the bottom of the sea for fixing after the ship arrives at the migration destination. The invention adopts a fostering method in the migration of the corals, leads the scleratinia not to reduce survival rate or be dead due to the environment without water for a long time and leads the survival rate of the scleratinia to be more than 95 percent, thus being an effective ex-situ conservation method for the scleratinia.

Description

technical field [0001] The invention relates to an ex situ protection method for coral reefs, in particular to an ex situ protection method for reef-building coral (Scleratinia). Background technique [0002] Corals include soft corals, gorgonian corals, red corals, stony corals, horned corals, hydrocorals, blue corals, and sheng corals. Reef-building corals are shallow-water stony corals. Coral reefs are the habitat of a quarter of marine life in the world. The complex three-dimensional structure environment erected on coral reefs contains rich aquatic organisms, thus forming a community with high biodiversity. Therefore, corals are known as "ocean oasis" or The title of "Marine Tropical Rainforest". Reef-building corals are the skeleton of modern coral reefs. However, due to our continuous development and utilization of marine resources in recent years, many marine projects have caused huge irreversible damage to reef-building corals. For this reason, corals, especially ...

Problems solved by technology

[0003] At present, there are very few researches on ex situ coral protection in the world, and they are basically in the initial stage of exploration. In China, only Chen Gang and others have carried out small-scale coral transplantation experiments in 1995. At that time, the number of transplanted corals was relatively small (total 44 samples), and the experiment was carried out in the same sea area. Although the final result showed that the transplantation was feasible, it did not involve the ex situ protection of corals, and there was no investigation on the selection of the relocation site, transportation and handling during the transplantation process. detailed discussion, so the feasibility of such a transplant is limited
