Description

Technical Field

[0001] The utility model relates to the technical field of ocean protection and ecological restoration, in particular to a shellfish and algae reef. Background Art

[0002] Marine reefs are reef structures with important topographic significance formed by the aggregation of marine organisms with reef-building ability. These reef structures are usually formed by the aggregation of only one or two reef-building organisms or by the accumulation of marine organisms, organic and inorganic substances. The three-dimensional structure formed provides habitats for other marine organisms and greatly increases the heterogeneity of the habitat environment of marine organisms. The formation of marine reefs changes the seabed topography, increases the complexity of the terrain at different scales, affects the water flow conditions near the reefs, and plays an important role in protecting the coastline from erosion, providing habitats for other species and maintaining marine biodiversity, purifying water bodies and fixing carbon.

[0003] When marine reefs are damaged, their structure and function will be damaged to varying degrees. If they are not repaired in time, they may lead to a series of consequences or even extinction. There are two methods for ecological restoration of marine reefs: one is to place reef-building organisms in degraded reef areas to create good living conditions for them so that they gradually gather into reefs; the other is to place artificial reefs made of concrete and environmentally friendly materials to guide the larvae of gregarious reef-building organisms to settle and gather, that is, to supplement reef-building organisms to gradually form reefs.

[0004] At present, the technologies related to marine ecological restoration at home and abroad are mainly focused on the ecological restoration of a single ecosystem, community or species. For example, the invention patent with application number CN201510772345.3 discloses a method for constructing an artificial composite reef to assist in the restoration of damaged oyster reefs. The restoration of damaged oyster reef ecosystems is assisted by constructing a triangular-configuration oyster reef. In this method, the object of ecological restoration is single, and only the single species of oyster is restored. In repairing the problem of marine biological degradation, there is still a certain deficiency in restoring the diversity of marine organisms. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to provide a shellfish and algae reef in view of the above existing problems.

[0006] The technical solution adopted by the utility model is: a shellfish reef, characterized in that it comprises:

[0010] Through the above technical means, oyster reefs are used to provide a growth environment for shellfish, and algae reef matrix is ​​used to provide a growth environment for algae. The combination of oyster reefs and algae reef matrix to form shellfish and algae reefs can improve the biodiversity in the target restoration sea area. At the same time, the through holes on the oyster reef can play a certain role in energy dissipation, and can also provide a suitable habitat for marine life, which can effectively repair the problem of marine biological degradation.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0026] Embodiment 1:

[0027] Combination Figure 1 As shown, this embodiment is a shellfish algae reef, including an oyster reef 1, an algae reef groove 4 and an algae reef matrix 6. A through hole 3 penetrating the body is opened on the side wall of the oyster reef 1, and the top of the oyster reef 1 is hollowed out along the axial direction to be connected with the through hole 3. An algae reef groove 4 is provided on the top of the oyster reef 1. A certain height is reserved inside the algae reef groove 4 to facilitate the installation and embedding of the algae reef matrix 6 in the algae reef groove 4, and seaweed 7 is provided on the algae reef matrix 6.

[0028] In some embodiments, the oyster reef 1 is in the shape of a prism. Specifically, in this embodiment, the oyster reef 1 is in the shape of a hollow quadrangular pyramid, and the through hole 3 is in the shape of a triangle. The through hole 3 is conducive to reducing the scouring of the oyster reef 1 by seawater, and can also provide a place for fish and other marine life to avoid enemies and live. The algae reef tank 4 is in an open square structure, and the algae reef matrix 6 is in a porous cube structure. The size of the algae reef matrix 6 is slightly larger than the size of the algae reef tank 4 in the tank, so as to fit the inner wall of the algae reef tank 4 firmly. The algae reef matrix 6 can provide an attachment base for attached organisms such as large seaweed. The porous structure of the algae reef matrix 6 is conducive to the attachment of large algae robes. The algae reef matrix 6 is composed of a composite material of plant fiber and high molecular polymer fiber.

[0029] In some embodiments, a plurality of guide plates 2 are provided on the side wall surface on either side of the oyster reef 1. The guide plates 2 have a triangular prism structure and can consume energy and reduce the impact of waves on the coast.

[0030] In some embodiments, lifting rings 5 ​​are installed on opposite sides of the top of the oyster reef 1, and the lifting rings 5 ​​are used for constructing and placing the shellfish reef.

[0031] In some embodiments, oyster seedlings are arranged on the oyster reef 1, and the oyster seedlings should be selected from species in the marine restoration site, such as long oysters, Kumamoto oysters, and Omi oysters. Seaweed 7 uses seaweed seedlings, and the seaweed seedlings should be selected from large seaweed species in the marine restoration site, such as Gracilaria, Sargassum, Undaria, and Laminaria. When the oyster seedlings and seaweed seedlings mature, the shellfish reef is transported to the marine restoration site.

[0032] Embodiment 2:

[0033] This embodiment is a method for using a shellfish reef, which is applied to a shellfish reef as described in the first embodiment, and includes the following steps:

[0034] First, the algae reef matrix 6 is installed and embedded in the algae reef groove 4 on the top of the oyster reef 1, and then the roots of the large algae seedlings cultivated in the laboratory are inserted into the porous algae reef matrix 6, and placed in a laboratory incubator or an offshore aquaculture area. After the oyster reef 1 and the algae reef matrix 6 mature, the cultivated mature shellfish algae reef is transported to the ecological restoration area. The mature reef body has a certain scale and biological attachment, which can attract and promote the recovery of the surrounding ecosystem more quickly, and can also immediately provide a stable living environment for marine life, which is conducive to the rapid reproduction and growth of the population.

[0035] Before the annual breeding season, which is approximately May to June, during the low tide period, the cultivated mature shellfish and algae reefs are released into the sea restoration area in varying amounts according to needs. The appropriate water depth for release is 2m to 6m. When the algae reefs form a certain biological community scale, they can effectively reduce the impact of waves on the coast and reduce shoreline erosion.

[0036] Shell and algae reefs can also be combined in different amounts according to project needs to form different ecological restoration areas, effectively improving marine biodiversity and further protecting the coast.

[0037] As time goes by for restoration, shellfish reefs can play a role in managing the water quality of the sea area, absorb excess nutrients and heavy metal ions and other pollution in the water, increase the amount of related biological resources, form a small ecosystem by utilizing the relationship of the food web, promote the improvement of biodiversity, and then improve the ecological environment of the sea through the interaction between organisms and the environment.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
