For example, the invention patent (patent number 201510772345.3) constructs a triangular oyster reef to assist in the restoration of damaged oyster reef ecosystems. This method often uses the ecological restoration of a single oyster species and only increases the hard surface for oysters to attach. At present, there are still certain defects in the technology for marine protection and ecological restoration. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an algae reef system that can both dissipate energy and promote biodiversity. The algae reef system has a stable structure and can effectively resist the scouring of waves; the three-dimensional habitat structure provides numerous microhabitats while reducing tidal power, significantly enhancing marine biodiversity; shellfish and algae grow on the surface and inside the reef, which can provide shade and shelter for marine crustaceans and other invertebrates, effectively increasing the complexity of the habitat.

[0004] The utility model is realized through the following technical solutions.

[0005] The utility model provides an algae reef system with the functions of both dissipating energy and promoting biodiversity, comprising a bottom plate, a fixing plate and a seaweed growth carrier, wherein the fixing plates are located at both sides of the bottom plate, the seaweed growth carrier is a tube body with a hollow surface, the interior of which is filled with biological shells and sealed at both ends, the seaweed growth carrier is horizontally placed above the bottom plate, and the two ends are fixed on the fixing plates, through holes are provided on the fixing plates, and ropes are passed through the through holes to bind the seaweed seedlings.

[0006] Furthermore, the fixing plate is a semicircular structure with a plurality of mounting holes on its surface, and both ends of the shell algae growth carrier extend from the mounting holes of the fixing plate to fix the shell algae growth carrier.

[0007] Furthermore, the distance between adjacent mounting holes is not less than 20 cm.

[0008] Furthermore, the through holes are arranged in an arc shape along the fixing plate, and the distance between adjacent through holes is not less than 20 cm.

[0009] Furthermore, the diameter of the shellfish algae growth carrier is between 20 and 30 cm.

[0010] Furthermore, the base plate and the fixing plate are made of eco-concrete.

[0011] Furthermore, the biological shells are selected from one or more of oyster, abalone, and scallop shells, and the seaweed seedlings are selected from one or more of the genera Gracilaria, Sargassum, Undaria, and Laminaria.

[0012] The beneficial effects of the utility model are:

[0013] 1. The system structure proposed by the utility model is stable and can effectively resist the scouring of waves; the three-dimensional habitat structure reduces the tidal force while providing numerous microhabitats, significantly enhancing the marine biodiversity; shellfish and algae grow on the surface and inside the reef, providing shade and shelter for marine crustaceans and other invertebrates, effectively increasing the complexity of the habitat.

[0014] 2. When the shellfish and algae reef is submerged under water, the waves are affected by the rapid change of water depth and the friction of the bottom during the process of propagating from the deep sea to the nearshore, causing shallowing, fragmentation and attenuation along the reef. Compared with the traditional single-stage reef, the energy dissipation effect of the structure of the present invention is more significant than that of a single body.

[0020] Example 1

[0021] This embodiment introduces an algae reef system that has the functions of both dissipating energy and promoting biodiversity, including a bottom plate 1, a fixed plate 2 and a shellfish algae growth carrier 3. The fixed plate 2 is located on both sides of the bottom plate 1. The shellfish algae growth carrier 3 is a tube body with a hollow surface, filled with biological shells inside, and sealed at both ends. The shellfish algae growth carrier 3 is placed horizontally above the bottom plate 1, and its two ends are fixed on the fixed plate 2. The fixed plate 2 is provided with a through hole 4, and a rope is passed through the through hole 4 to bind the seaweed seedlings.

[0022] Among them, the hollow surface of the shell algae growth carrier means that the surface and both end faces of the shell algae growth carrier are covered with small holes, similar to a net.

[0023] As an optional embodiment, the fixing plate 2 is a semicircular structure with a plurality of mounting holes on its surface. The diameter of the fixing plate 2 is slightly larger than the diameter of the algae growth carrier 3. Both ends of the algae growth carrier 3 extend from the mounting holes of the fixing plate and can be fixed with clamps, buckles and screws. The clamps, buckles and screws are made of stainless steel resistant to seawater corrosion.

[0024] As an optional embodiment, the distance between adjacent mounting holes is not less than 20 cm.

[0025] As an optional embodiment, the through holes 4 are arranged in an arc shape along the upper edge of the fixing plate 2, the diameter of the through holes 4 is slightly larger than the diameter of the hemp rope, and the spacing between adjacent through holes 4 is not less than 20 cm.

[0026] As an optional embodiment, the shell algae growth carrier 3 is cylindrical, with a diameter between 20 and 30 cm.

[0027] As an optional embodiment, the bottom plate 1 is a rectangular parallelepiped, which plays the role of buffering the sinking of the algae reef system and supporting it.

[0028] As an optional embodiment, the rope is made of, for example, brown rope.

[0029] As an optional embodiment, the base plate 1 and the fixing plate 2 are made of ecological concrete.

[0030] As an optional embodiment, the biological shell is one or more of oyster, abalone, and scallop shells. Abandoned biological shells can be used, which are cleaned with a high-pressure water gun, sterilized by direct sunlight, and then placed in a shellfish algae growth carrier, or oyster seedlings cultivated in a laboratory are placed in a shellfish algae growth carrier, and then both sides of the shellfish algae growth carrier are sealed, and then placed in a laboratory incubator or an offshore aquaculture area to form an oyster reef. The shellfish algae growth carrier is a hollow cylinder with a certain strength, which provides an attachment base for the biological shell, and the biological shell and the shellfish algae growth carrier form a shellfish algae growth carrier monomer.

[0031] Using ecological concrete, bio-shells and other materials as anchor reefs for marine organisms, creating a habitat suitable for different marine species can provide a place for marine organisms to survive, rejuvenate and conserve coastal community-building species and key species, protect coastal biodiversity, repair the problem of marine biological degradation, and protect and improve marine biodiversity.

[0032] As an optional embodiment, oyster seedlings should be selected from local species, such as Hong Kong oysters, Fujian oysters, long oysters, Kumamoto oysters, Omi oysters, etc.; seaweed seedlings should be selected from local large seaweed species, such as Gracilaria, Sargassum, Undaria, Laminaria, etc.

[0033] Before the annual breeding season, which is approximately May to June each year, during the low tide period, the cultivated mature reefs will be released into the sea restoration area in varying amounts according to the needs of the project. The suitable water depth for release is 2 to 6 meters.

[0034] Algal reefs can be combined in varying amounts into different ecological restoration areas according to project needs, effectively protecting embankments and improving marine biodiversity.

[0035] When the algae reef forms a certain scale of biological community, it can effectively reduce the impact of waves on the coast and reduce shoreline erosion. In addition, shellfish and seaweed are natural water purification systems that can play a role in marine water quality management. Algae reefs absorb excess nutrients and heavy metal ions in the water, increase the amount of related biological resources, form small ecosystems through the relationship of food webs, promote biodiversity, and then improve the marine ecological environment through the interaction between organisms and the environment. Moreover, when the shellfish and algae reefs are submerged underwater, the waves are affected by the rapid changes in water depth and friction on the bottom during the process of propagating from the deep sea to the nearshore, shallowing, fragmentation and attenuation along the reef occur, and the energy dissipation effect is significant.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
