Problems solved by technology

[0003] At present, most of the foreign reports on stony coral protection technology are the United States, Australia, East Africa and other countries, some governments or environmental protection organizations have invested artificial reefs in sea areas where corals are threatened, and artificially repaired damaged coral reefs, and achieved good results. , but these methods are often time-consuming, labor-intensive, and costly
However, there is no effective method for cultivating stony corals in natural sea areas in China.
Therefore, the situation of protecting corals is very serious

Embodiment 1

[0034] This embodiment first introduces the structure of the cultivation device, as figure 1 As shown, the cultivation and planting device includes an overhead support reef 1, a coral net garden 2 and a coral fixer 3, wherein the top of the overhead support reef 1 is fixedly connected to the coral net garden 2, and the coral net garden 2 adopts a flat transparent grid structure, the coral fixer 3 is embedded in the grid hole 21 of the grid structure, and the coral fixer 3 is connected with the coral net garden 2.

[0035] Wherein, the quantity of coral anchor 3 is multiple, and a plurality of coral anchor 3 is evenly distributed on coral net garden 2, between coral anchor 3 and adjacent coral anchor 3, keep the distance of 15-20cm.

[0036] In this embodiment, the top of the overhead support reef 1 is provided with a first fixed arm 4 and a second fixed arm 5, and there is a distance between the first fixed arm 4 and the second fixed arm 5, and the distance range is 30cm-50cm....

Embodiment 2

[0039] Present embodiment is on the basis of embodiment 1, introduces stony coral cultivation and planting method, and its specific scheme is as follows:

[0040] The first step is to select an area with a low coral coverage rate to place a coral planting device. There are coral reefs near the location where the coral is selected, and the coral netting point is close to the bait-enriched sea area.

[0041] The second step is to investigate the history of the selected sea area and the current composition of the coral community to select suitable coral species for cultivation; in addition, the cultivation device is put into the selected sea area 10-15 days in advance.

[0042] The third step is to select a healthy, mature primary coral mother plant with limited growth space as the transplant object after the coral breeding season. After the coral breeding season is generally September-November, when the stony coral has passed the spawning period, the water temperature is suitabl...

Embodiment 3

[0052] In August 2014, in the Xuwen Peninsula Marine Nature Reserve, the sea area suitable for putting in coral planting devices was selected through exploration. The sea area where coral reefs are put in should lack the accumulation of coral reefs, and there should be accumulations of coral reefs above or below the tide, and the arrangement of coral planting devices The way is 75° to the direction of the tide. Take the overhead support reef as the support base, the diameter of the overhead support reef is 3m, and the height is 1.2m. There are two stainless steel fixed arms connected to the overhead support reef, both of which are 10cm long, and the horizontal distance between the two arms is 60cm. The coral is fixed by tightening a square nut Net gardens on coral reefs. The coral net garden is made of fiberglass grating, which is a rectangular hollow grid structure with a length of 2m, a width of 1.5m and a thickness of 5cm. In fine weather, transport the overhead support re...

Abstract

The invention relates to a method for cultivating stony corals in natural sea areas. The method uses a cultivation and planting device for planting, so that stony corals can overcome the unfavorable environment in natural sea areas and grow rapidly in an improved growth environment.

Description

technical field [0001] The invention relates to the field of marine environment restoration, and more specifically, to a method for cultivating and planting stony corals in natural sea areas. Background technique [0002] Stony corals generally grow in the subtropical and tropical coastal waters of my country, and the distribution depth is mostly no more than 40 meters. At present, there are 86 genera and more than 1,000 species found in the Indo-Pacific region. Stony corals are group-aggregating organisms with colorful and lovely colors in the water. They are important species of coral reefs in my country and play an important role in maintaining the stability of natural ecosystems. Stony corals have particularly high requirements for water quality. Changes in environmental factors such as temperature, salinity, heavy metals, and eutrophication levels will have an impact on the stony coral reef ecosystem. In recent years, with the deterioration of coastal water quality and...
