Embodiment 1

[0033] Such as figure 1 The shown oyster reef unit matrix 1 is a hexagonal prism hollow structure, its cross section is a regular hexagon, and its side is provided with hollow through holes 3 .

[0034] Such as figure 2 The shown oyster reef unit daughter body 2 is a mesh strip bag with built-in oyster shells.

[0035] Further, the material of the oyster reef unit matrix 1 is reinforced concrete.

[0036] Further, the hollow through holes 3 on the outer side of the hexagonal prism structure are used for the connection between the oyster reef unit mother body 1 and the fixation of the oyster reef unit sub-body 2 .

[0037] Furthermore, the single length of the oyster reef unit matrix 1 is 50 cm, and the diameter of the inscribed circle of the hexagonal prism cross section is 20 cm.

[0038] Further, the mesh bag used in the oyster reef unit daughter body 2 should be biodegradable material polylactic acid (PLA) or polybutylene succinate (PBS).

[0039] Further, the mesh bag...

Embodiment 2

[0043] The making of ecological oyster reef body is obtained as described in step (1) and step (2) of embodiment 1, a kind of construction of intertidal zone ecological oyster reef system and its delivery method, another approach: (a) in Oyster content is less than 5% sea area intertidal zone, the step (2) ecological oyster reef reef body described in embodiment 1 is placed in the incubator of laboratory or aquaculture area in different quantities and carries out seedling cultivation; (b) will When the fertilized eggs collected in the laboratory are cultivated until the tentacles can be attached, they are placed in the incubator described in step (a); (c) after the oyster reef in the incubator is mature and stable, before the oyster breeding period every year It will be placed in the intertidal zone of the target sea area in about March, and the depth of the sea area will be about 2 to 6 meters.

[0044] The method implemented in the present invention is based on the biologica...

Abstract

The invention discloses a preparation method of an intertidal zone ecological oyster reef system. The preparation method comprises construction, cultivation and putting of oyster reef bodies. According to the preparation method, the oyster reef configuration is selected to be of a honeycomb structure, the honeycomb structure has the highest adaptation, strong extrusion resistance and maximum available space, and materials are saved; and meanwhile, the honeycomb structure can trap other small benthic animals and microorganisms to create a biological habitat. By means of the method, the multiple purposes of remarkably increasing the survival rate and biomass of oysters, improving the biodiversity of offshore intertidal zones and purifying the water environment of offshore sea areas can be achieved. Meanwhile, based on the tidal characteristics of the intertidal zones, the reef bodies can achieve circulating updating of a water body, and free flowing and exchanging of water flow are achieved. The method can provide a solution for regions where the ecological environment of the intertidal zones is shrunk, degraded and destroyed.

Description

technical field [0001] The invention relates to the technical field of oyster reef ecological restoration, in particular to a method for preparing an intertidal ecological oyster reef system. Background technique [0002] Oyster reef is a reef formed by layer upon layer of oysters continuously attached to the oyster shell. Oyster reefs can provide a variety of ecosystem services: providing shelter for marine organisms, purifying offshore water quality, protecting coastlines from erosion, maintaining ecological balance in coastal zones, etc. According to data, due to overfishing, seawater pollution, coastal development and other reasons, 85% of the world's oyster reefs have disappeared. Small, and the oyster population is dwindling. At the same time, due to the sharp decline in the number of oyster reefs, there are fewer habitats for marine benthos and seabirds in the coastal intertidal zone, which has seriously damaged offshore biodiversity. In recent years, Chesapeake Ba...
