Embodiment 1

[0027] The regeneration method of stony coral comprises the following steps:

[0028] 1. Collection of small pieces of coral: In the natural distribution area of ​​corals along the eastern coast of Shenzhen, from June to September 2015, we collected small pieces of small branches of healthy staghorn corals with a length of about 2 to 3 cm around the mother plant with restricted growth, and kept them temporarily in the aquarium in the box.

[0029]2. Sterilization and disinfection of small coral pieces: Put the small pieces of coral in the culture tank and wash them with sterilized seawater for 2 minutes, then soak them in the special disinfectant containing Seachem (sea chemical) Reef Dip from low to high concentration. The concentration of the disinfectant is in order 5ppm, 10ppm, 20ppm, 40ppm and 80ppm, soak for 30 seconds in each concentration, and then put the coral pieces in a circulating water tank and rinse with sterilized seawater for 2 minutes.

[0030] 3. Preparatio...

Embodiment 2

[0039] The experimental method is the same as in Example 1, the only difference is that step (4) is carried out as follows:

[0040] (1) Cut a 5.5 cm thick granite slab into units of 55 cm x 85 cm x 5.5 cm. Drill holes in the granite slab at intervals of 15 cm and a depth of 5 cm for planting small pieces of coral.

[0041] (2) Put the 55 cm × 85 cm × 5.5 cm granite culture plate in the circulating water tank, water will flow in from the water outlet to replenish, add water to cover the culture plate for about 50 cm, and install the culture plate on the wall plate at a distance of 20 cm from the water surface. Wave machine, making waves at a frequency of 15 times per minute. Add calcium carbonate and calcium chloride to make the calcium concentration 600ppm, and make the alkalinity 6meq / L, pH 8.0; connect CO 2 Storage tank and gas pump, regulating CO 2 The concentration is 33ppt, the dissolved oxygen is greater than 8mg / L; the ammonia value is guaranteed to be less than 0.1p...

Embodiment 3

[0044] The experimental method is the same as in Example 1, the only difference is that step (4) is carried out as follows:

[0045] (1) Cut a 5.5 cm thick granite slab into units of 55 cm x 85 cm x 5.5 cm. Drill holes in the granite slab at intervals of 15 cm and a depth of 5 cm for planting small pieces of coral.

[0046] (2) Put the 55 cm × 85 cm × 5.5 cm granite culture plate in the circulating water tank, water will flow in from the water outlet to replenish, add water to cover the culture plate for about 50 cm, and install the culture plate on the wall plate at a distance of 20 cm from the water surface. Wave machine, making waves at a frequency of 15 times per minute. Add calcium carbonate and calcium chloride to make the calcium concentration 800ppm, and make the alkalinity 6meq / L, pH 8.5; connect CO 2 Storage tank and gas pump, regulating CO 2 The concentration is 33ppt, the dissolved oxygen is greater than 8mg / L; the ammonia value is guaranteed to be less than 0.1p...

Abstract

The invention discloses an artificial regeneration method of stony coral, which is to collect healthy 2-3cm stony coral branches in natural sea areas where stony corals are mainly distributed as small pieces of coral, transfer them to indoors for cultivation, and clean, disinfect and sterilize indoors. , the coral is fixed in a ceramic coral fixer by underwater adhesive, and the coral fixer is inserted into the substrate in the indoor circulating water culture tank for activation. Under artificial control conditions, the coral flakes recover their vitality and grow rapidly. Improve the immunity. In the natural sea area, choose dead stony coral skeletons on the seabed, clean them with ultrasonic pulse oscillation, graft small pieces of coral into the dead stony coral skeletons for diffusion and reproduction, and promote the rapid regeneration of dead corals; Small pieces of coral are low in cost; in addition, indoor cultivation is used to provide a suitable growth environment, which can quickly cultivate coral growth, and quickly obtain small pieces of coral with the required specifications suitable for transplantation.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an artificial regeneration method for stony corals. Background technique [0002] Stony corals generally grow in the subtropical and tropical offshore waters of my country. At present, 86 genera and more than 1,000 species have been found in the Indo-Pacific region. Stony corals are group-aggregating organisms with colorful and lovely colors in the water. They are important constituent species of coral reefs in my country. Their biodiversity and high primary productivity play an important role in maintaining the stability of natural ecosystems, and at the same time provide human beings with rich resources. Excellent material products and high appreciation aesthetic value. However, stony corals have particularly high requirements for water quality, and changes in environmental factors such as temperature, salinity, heavy metals, and eutrophication levels will have an impact on...
