Embodiment 1
[0019] Such as figure 1 As shown, the cultivating device of the present embodiment includes a plastic bucket 1 with a height of 50-60 cm and an inner diameter of 15-20 cm and a plastic tube 2 with a length of 20-30 cm. One end of the plastic tube is sealed with a filter screen with an aperture of 120-200 μm. Live, the filter screen is tightly sealed with the plastic pipe 2, and there must be no gaps and folds, so as to prevent the coral fertilized eggs from flowing out of the plastic pipe 2 with sea water or being trapped in the folds. All cultivation devices should be sterilized with 0.5% potassium permanganate solution before use, rinsed with fresh water, and fresh clean seawater should be added to the plastic bucket (avoid collecting seawater in polluted sea areas. The collected seawater should It is best to use a sieve with a pore size of 20 μm to filter, and if it can be filtered with a filter membrane of 0.2 μm, the effect will be better.) to a height of 30-35 cm, and ke...

The invention discloses a culture method and a culture device used before attachment of coral oosperms. A plurality of culture round tubes are arranged in a seawater container; one end of each culture round tube is sealed by a filter screen, and the other end of each culture round tube is provided with an opening; each culture round tube is placed in the seawater container in a manner that the filter screen end of each culture round tube is downward and the opening end of each culture round tube is upward; fresh and clean seawater is added into the seawater container, and the water temperature of the seawater is maintained at 27-28DEG C, so that the filter screen end of each culture round tube is in the seawater, and the opening end of each culture round tube is exposed to the water surface, so that the culture water surface area in each culture round tube is 176-314cm<2>; the coral oosperms are poured into the culture round tubes along with the seawater, wherein the number of the coral oosperms in each culture round tube is 1,000-1,500; the seawater in the culture round tubes and the seawater container is frequently replaced so as to maintain the cleanness of the culture environment; and if dead and albescent individuals of the coral oosperms exist, the dead and albescent individuals are sucked out, and culture based on such a method is carried out until the coral oosperms develops to planula. By utilizing the method and device disclosed by the invention to culture the coral oosperms, the survival rate of the coral oosperms can be greatly improved.
Description
Technical field: [0001] The invention belongs to the field of coral cultivation and artificial restoration of coral reefs, and in particular relates to a cultivation method and cultivation device for coral fertilized eggs before attachment. Background technique: [0002] Corals have been threatened more and more in the past 50 years. Under the double pressure of human influence and global warming, the number is rapidly decreasing, and many coral reefs have been degraded worldwide. The reduction of coral makes coral reefs and island reefs formed by coral reefs eroded and damaged by waves and storms beyond repair, and coral reefs and island reefs will gradually shrink and disappear under erosion. In addition, the number of organisms living in coral reefs will be greatly reduced and biodiversity will be reduced, which also affects the catch of fisheries and the income of fishermen. In order to slow the decline rate of coral populations, increase coral populations, maintain bio...
